Opera Cake

By kmorganmoss • May 28th, 2008 • Category: Desserts, EventsPrint This Post Print This Post

It’s a Daring Baker Challenge and this time we are going to the Opera. Well you might be going to the Opera, I on the other hand might be going to the nut house as this event brought out the perfectionist in me. Not the good give it your all perfectionist that is a fine quality to have. Instead I learned that I have a somewhat tormented perfectionist personality. Not a pretty site, let me tell you. The Opera Cake has nothing to do with Southern cooking, but once a month I look the other way and take the Challenge.

But before we get started, please note that my site has been a work in progress this past week and will continue to be so over the coming week. As you can see, I am having trouble balancing the feminine/masculine aspects of my personality and expect to get this worked out rather quickly. Otherwise I am apt to have an identity crisis.

It could very well take me a month for me to recover from this challenge. I gave myself the much needed full two days for this one. This was my first time for making all of the components of a cake of this magnitude. I had a few major and minor mishaps with a lot of sweating to pull this off. I discovered a lot about cake making in addition to learning about myself. I thought instead of the long winded writing that I usually do in between images, I would list what I learned during this challenge.

My list is in no particular order and I am jotting them down as they pop up in what room is left in my brain.

But first I would like to thank our lovely hosts Lis & Ivonne as well as our co hosts Fran from Apples Peaches Pumpkin Pie & Shea from Whiskful for picking the Opera Cake, and yes I do mean this. I loved the cake, it was decadent and light and creamy all at the same time. Please do take the time to visit the Daring Baker’s Blogroll and see some incredible works of art.

So here goes………..The Opera Cake!
Jocande- Vanilla………..Syrup-Almond…………Butter cream-Vanilla ………….Ganache Mousse-Vanilla White Chocolate…………..Glaze-White Chocolate…………….Flowers-edible & sugar coated rose petals.

My list of things I learned about cake & myself during the Opera challenge.

  • I really like making cakes.
  • I really like eating cakes, especially a white cake.
  • I took the time to learn how to make a real butter-cream, ganache mousse, and a glaze and I am thrilled.
  • Buttercream makes a good glue to hold the flowers in place.
  • Even though I minored in math and am good at it; sometimes I can’t measure a baking sheet pan and get it right.
  • When I make a mistake like baking the whole cake batter in one pan instead of two; I am resourceful and slice the layers in half.
  • I need a new sharp serrated knife as # 5 was quite difficult to do with my dull knife.
  • Uneven cake slices triggers my perfectionism.
  • Belonging to the Daring Bakers is fun, and I am so glad I signed up.
  • It is easier to work with butter-cream & ganache when it is firmer.
  • It is easier to work with the glaze when it is thinner.
  • It is easier to make an Opera Cake when you aren’t sweating like a pig.

  • I am out of shape because bending up and down outside for about 2 hours to take photos, nearly wore me out.
  • You have about 3 minutes with the warm Charleston weather to take photos of a cake before you have to run back inside to put it in the frig again and grab another cake.
  • It is hard taking a photo while remaining still as you try to swat a fly from a cake.
  • Don’t let the dog outside with you while trying to take photos of food.
  • I like cake, so I kept going even though I wanted to call it a day or a week or something.
  • I can make a pretty good cake even if I do say so.
  • It is easy for me to spot all the flaws.
  • I am going to need therapy after this challenge to debrief from all the components.
  • I need a hands on egg-white beating tutorial, as I am not so sure about soft, medium, stiff……….
  • I have a heck of a lot more patience than I would have ever thought, and I am old enough to have known this. I’m glad I figured this out.
  • I need to clean out my refrigerator as I had trouble finding room for all the cakes.

  • I haven’t stayed up this late in ages (3pm).
  • I would love to take photo lessons and really learn how to use my camera.
  • A challenge is fun for me, and pushes me to grow and learn.
  • I have a real feminine side as exhibited by the Opera Cakes.
  • This is freaking me out as it is real girly and I am a minimalist which a touch of casual chic thrown in.
  • Well this week, my minimalist outfit has been casual sweats and a t-shirt, no chic.
  • I am afraid of color, and am most comfortable with white,green, beige and black.
  • I will Let God and Let Go.
  • And I am going to call it a night to have sweet Opera Cake Dreams.

If you are inclined to make this cake and I do suggest you give an Opera Cake a chance when you have the time.

A Taste of Light: Opéra Cake

This recipe is based on Opéra Cake recipes in Dorie Greenspan’s Paris Sweets and Tish Boyle and Timothy Moriarty’s Chocolate Passion.

For the joconde

(Note: The joconde can be made up to 1 day in advance and kept wrapped at room temperate)

What you’ll need:

•2 12½ x 15½-inch (31 x 39-cm) jelly-roll pans (Note: If you do not have jelly-roll pans this size, do not fear! You can use different-sized jelly-roll pans like 10 x 15-inches.)
•a few tablespoons of melted butter (in addition to what’s called for in the ingredients’ list) and a brush (to grease the pans)

  • parchment paper
  • a whisk and a paddle attachment for a stand mixer or for a handheld mixer
  • two mixing bowls (you can make do with one but it’s preferable to have two)

Ingredients:

6 large egg whites, at room temperature
2 tbsp. (30 grams) granulated sugar
2 cups (225 grams) ground blanched almonds (Note: If you do not want to use almond meal, you can use another nut meal like hazelnut. You can buy almond meal in bulk food stores or health food stores, or you can make it at home by grinding almonds in the food processor with a tablespoon or two of the flour that you would use in the cake. The reason you need the flour is to prevent the almonds from turning oily or pasty in the processor. You will need about 2 cups of blanched almonds to create enough almond meal for this cake.)
2 cups icing sugar, sifted
6 large eggs
½ cup (70 grams) all-purpose flour
3 tbsp. (1½ ounces; 45 grams) unsalted butter, melted and cooled

1.Divide the oven into thirds by positioning a rack in the upper third of the oven and the lower third of the oven.

2.Preheat the oven to 425?F. (220?C).

3.Line two 12½ x 15½- inch (31 x 39-cm) jelly-roll pans with parchment paper and brush with melted butter.

4.In the bowl of a stand mixer fitted with the whisk attachment (or using a handheld mixer), beat the egg whites until they form soft peaks. Add the granulated sugar and beat until the peaks are stiff and glossy. If you do not have another mixer bowl, gently scrape the meringue into another bowl and set aside.

5.If you only have one bowl, wash it after removing the egg whites or if you have a second bowl, use that one. Attach the paddle attachment to the stand mixer (or using a handheld mixer again) and beat the almonds, icing sugar and eggs on medium speed until light and voluminous, about 3 minutes.

6.Add the flour and beat on low speed until the flour is just combined (be very careful not to overmix here!!!).

7.Using a rubber spatula, gently fold the meringue into the almond mixture and then fold in the melted butter. Divide the batter between the pans and spread it evenly to cover the entire surface of each pan.

8.Bake the cake layers until they are lightly browned and just springy to the touch. This could take anywhere from 5 to 9 minutes depending on your oven. Place one jelly-roll pan in the middle of the oven and the second jelly-roll pan in the bottom third of the oven.

9.Put the pans on a heatproof counter and run a sharp knife along the edges of the cake to loosen it from the pan. Cover each with a sheet of parchment or wax paper, turn the pans over, and unmold.

10.Carefully peel away the parchment, then turn the parchment over and use it to cover the cakes. Let the cakes cool to room temperature.

For the syrup

(Note: The syrup can be made up to 1 week in advance and kept covered in the refrigerator.)

What you’ll need:

  • a small saucepan

Ingredients:

½ cup (125 grams) water
? cup (65 grams) granulated sugar
1 to 2 tbsp. of the flavouring of your choice (i.e., vanilla extract, almond extract, cognac, limoncello, coconut cream, honey etc.)

1.Stir all the syrup ingredients together in the saucepan and bring to a boil.

2.Remove from the heat and let cool to room temperature.

For the buttercream

(Note: The buttercream can be made up to 1 month in advance and packed in an airtight container. If made way in advance, you can freeze the buttercream. Alternatively you can refrigerate it for up to 4 days after making it. To use the buttercream simply bring it to room temperature and then beat it briefly to restore its consistency.)

What you’ll need:

  • a small saucepan
  • a candy or instant-read thermometer
  • a stand mixer or handheld mixer
  • a bowl and a whisk attachment
  • rubber spatula

Ingredients:

1 cup (100 grams) granulated sugar
¼ cup (60 grams) water
seeds of one vanilla bean (split a vanilla bean down the middle and scrape out the seeds) or 1 tbsp. pure vanilla extract (Note: If you are flavouring your buttercream and do not want to use the vanilla, you do not have to. Vanilla will often enhance other flavours but if you want an intense, one-flavoured buttercream, then by all means leave it out!)
1 large egg
1 large egg yolk
1¾ sticks (7 ounces; 200 grams) unsalted butter, at room temperature
flavouring of your choice (a tablespoon of an extract, a few tablespoons of melted white chocolate, citrus zest, etc.)

1.Combine the sugar, water and vanilla bean seeds or extract in a small saucepan and warm over medium heat just until the sugar dissolves.

2.Continue to cook, without stirring, until the syrup reaches 225?F (107?C) [*Note: Original recipe indicates a temperature of 255?F (124?C), however, when testing the recipe I found that this was too high so we heated to 225?F and it worked fine] on a candy or instant-read thermometer. Once it reaches that temperature, remove the syrup from the heat.

3.While the syrup is heating, begin whisking the egg and egg yolk at high speed in the bowl of your mixer using the whisk attachment. Whisk them until they are pale and foamy.

4.When the sugar syrup reaches the correct temperature and you remove it from the heat, reduce the mixer speed to low speed and begin slowly (very slowly) pouring the syrup down the side of the bowl being very careful not to splatter the syrup into the path of the whisk attachment. Some of the syrup will spin onto the sides of the bowl but don’t worry about this and don’t try to stir it into the mixture as it will harden!

5.Raise the speed to medium-high and continue beating until the eggs are thick and satiny and the mixture is cool to the touch (about 5 minutes or so).

6.While the egg mixture is beating, place the softened butter in a bowl and mash it with a spatula until you have a soft creamy mass.

7.With the mixer on medium speed, begin adding in two-tablespoon chunks. When all the butter has been incorporated, raise the mixer speed to high and beat until the buttercream is thick and shiny.

8.At this point add in your flavouring and beat for an additional minute or so.

9.Refrigerate the buttercream, stirring it often, until it’s set enough (firm enough) to spread when topped with a layer of cake (about 20 minutes).

For the white chocolate ganache/mousse (this step is optional - please see Elements of an Opéra Cake below)

(Note: The mousse can be made ahead and refrigerated until you’re ready to use it.)

What you’ll need:

  • a small saucepan
  • a mixer or handheld mixer

Ingredients:

7 ounces white chocolate
1 cup plus 3 tbsp. heavy cream (35% cream)
1 tbsp. liquer of your choice (Bailey’s, Amaretto, etc.)

1.Melt the white chocolate and the 3 tbsp. of heavy cream in a small saucepan.
2.Stir to ensure that it’s smooth and that the chocolate is melted. Add the tablespoon of liqueur to the chocolate and stir. Set aside to cool completely.
3.In the bowl of a stand mixer, whip the remaining 1 cup of heavy cream until soft peaks form.
4.Gently fold the whipped cream into the cooled chocolate to form a mousse.
5.If it’s too thin, refrigerate it for a bit until it’s spreadable.
6.If you’re not going to use it right away, refrigerate until you’re ready to use.

For the glaze
(Note: It’s best to make the glaze right when you’re ready to finish the cake.)

What you’ll need:

  • a small saucepan or double boiler

Ingredients:

14 ounces white chocolate, coarsely chopped
½ cup heavy cream (35% cream)

1.Melt the white chocolate with the heavy cream. Whisk the mixture gently until smooth.
2.Let cool for 10 minutes and then pour over the chilled cake. Using a long metal cake spatula, smooth out into an even layer.
3.Place the cake into the refrigerator for 30 minutes to set.

Assembling the Opéra Cake

(Note: The finished cake should be served slightly chilled. It can be kept in the refrigerator for up to 1 day).

Line a baking sheet with parchment or wax paper.

Working with one sheet of cake at a time, cut and trim each sheet so that you have two pieces (from each cake so you’ll have four pieces in total): one 10-inch (25-cm) square and one 10 x 5-inch (25 x 12½-cm) rectangle.

Step A (if using buttercream only and not making the ganache/mousse):

Place one square of cake on the baking sheet and moisten it gently with the flavoured syrup.

Spread about one-third of the buttercream over this layer.

Top with the two rectangular pieces of cake, placing them side by side to form a square. Moisten these pieces with the flavoured syrup.

Spread another third of the buttercream on the cake and then top with the third square of joconde. Use the remaining syrup to wet the joconde. Spread the remaining buttercream on top of the final layer of joconde and then refrigerate until very firm (at least half an hour).

Make the glaze and after it has cooled, pour/spread it over the top of the chilled cake. Refrigerate the cake again to set the glaze.

Serve the cake slightly chilled. This recipe will yield approximately 20 servings.

Step B (if making the ganache/mousse):

Place one square of cake on the baking sheet and moisten it gently with the flavoured syrup.

Spread about three-quarters of the buttercream over this layer.

Top with the two rectangular pieces of cake, placing them side by side to form a square. Moisten these pieces with the flavoured syrup.

Spread the remaining buttercream on the cake and then top with the third square of joconde. Use the remaining syrup to wet the joconde and then refrigerate until very firm (at least half an hour).

Prepare the ganache/mousse (if you haven’t already) and then spread it on the top of the last layer of the joconde. Refrigerate for at least two to three hours to give the ganache/mousse the opportunity to firm up.

Make the glaze and after it has cooled, pour/spread it over the top of the chilled cake. Refrigerate the cake again to set the glaze.

Serve the cake slightly chilled. This recipe will yield approximately 20 servings.

  1. Kim, you did a fabulous job! I love tormenting the guys in the kitchen with girly decorations and turn around and curse at them like a sailor for doing it wrong :) They are now convinced I have a split personality…

  11. Baking sure is a time for reflection huh :) Those flowers are so gorgeous on the cakes by the way.

  12. Just beautiful! I love the little cakes.

  13. I think your list of things you learned is hillarious. Especially the one about not letting the dog out while you’re trying to photograph cake! And your little cakes with the flowers are so pretty!

  14. You know how to make a nice picture of a cake! Beautiful combination with the flowers :-) Congratulations!

  15. It’s beautiful! That is one heck of a challenging recipe! Unreal!

  16. Those pictures are incredible! You’ve done a beautiful job with the challenge. I also had attacks of perfectionism when my cake wasn’t quite even… I had sagging corners because my cake was a little too thin.

  17. What a great job. Even with the soon to be summer heat of the south (which I for one do not miss). You cakes are just wonderful! I love all the pictures and different cakes.

  18. Kim I’m so happy to see this cake! Lovely with all the flowers.
    And your writing is a crack up. The guys just can’t figure how what can be learned from time in the kitchen. Thanks much for this one.

  19. Great learning list and truly beautiful little cakes!

  20. Beautiful, beautiful! I did not get to do the challenge this month, sadly. But you aced it!! OK, I say that based on the pictures alone - now I’m going to go back and read the post!

  21. Kim, that was truly a joy to read- had me smiling all the way through.

  32. The fresh flowers add such a nice element to the cake…beautiful!

  33. Those look, well, magnifique!

    Oh, and a crash tutorial in egg whites:
    1. Soft is when they look fluffy and foamy, and the peaks fall over when you lift up the beaters.
    2. Medium is when they still look foamy and the peaks stand up when you lift up the beaters, but the egg whites still slide around when you move the bowl.
    3. Stiff is when they look almost solid, and you can turn the bowl upside down and the egg whites don’t move.

  34. Good g-d! That is gorgeous!

  35. Kim very nice job! And also, I love your glass cake stand with the polkadots. Gorgeous!

  36. WOW! These are the most beautiful cakes I have ever seen. The flowers are gorgeous, the colors are amazing! I absolutely adore you! Your list is a riot! Many many kudos to you on this one. The ONLY thing wrong with them is that they look too good to eat!

    4. Since you need R&R after this challenge does this mean you are never going to make these again?
