Hey guys, it’s so hazy on these few days! 😑😑😑
Better all be careful while going out, especially those with baby and old folks along. 😓😓
That’s why I stay at home with my baby now a days but, today I got time to bake!😌
Since mom is babysitting for me, I decided to try on an opera cake.
Opera Cake is a type of French cake. It is made with layers of almond sponge cake (known as Joconde in French) soaked in coffee syrup, layered with ganache and coffee buttercream, and covered in a chocolate glaze. According to Larousse Gastronomique “Opéra gateau is an elaborate almond sponge cake with a coffee and chocolate filling and icing.”The cake was popularized by the French pâtisserie house Dalloyau.
My husband just loves this after he tried the opera cake that sell at RT PASTRY. I never try before, actually … But I think it should be nice because my husband doesn’t really like dessert. 😩😩
So, I decided to learn it and bake for him. No need buy from RT again. Haha … You see… Women…especially, wife & a mother of a baby … 😁 Calculative! On small tiny things … Stupid me! 😁😁😁
This time, I chose to bake a green tea flavour opera cake after all the search on the Internet. And, I came across this lady, Aran Goyoaga’s website and I found this. It was so beautiful on how she assemble the cake. So…I decided to bake my husband a new flavour of his favourite opera cake. 😁

Matcha Almond Sponge Cake
Makes 3 pieces of 1/4-sheetpan sheets(9″x13″)
160 grams almond flour
110 grams sugar
40 grams flour
15 grams matcha green tea powder
4 eggs
4 egg whites
55 grams sugar
30 grams unsalted butter, melted and cooled
1. In the bowl of an electric mixer combine the first five ingredients. Whip in high speed for about 5 minutes until it becomes thick and the batter forms a ribbon. Transfer this batter to a large bowl and clean the mixer bowl.
2. In the electric mixer, whip the egg whites until it starts to form a meringue. Slowly sprinkle the 55 grams of sugar. Continue whipping until a stiff meringue forms.
3. Fold a third of the meringue into the almond batter. Add the rest of the meringue and fold carefully not to deflate it too much. Add the melted and cooled butter and fold until it is well incorporated.
4. Divide the batter equally into the 3 quarter sheetpans that we have previously lined with parchment paper and sprayed with pan spray.
5. Bake in a 375 degree oven for about 10-12 minutes until it starts to turn a little brown. We don’t want a brown cake. We want to keep the green color so remove the pans from the oven when the cake is baked and before it starts to change color. Let the cakes cool until we are ready to assemble the opera.
Lemon Buttercream
60 grams egg whites
120 grams sugar
180 grams butter, softened
25 grams lemon juice
1/4 tsp lemon oil or 1/2 tsp lemon extract
1. Mix the egg whites and the sugar and place them over a double boiler while you whisk them together. The sugar will start to dissolve and the egg whites will start to turn white and fluffy. Continue whisking until the egg whites feel hot to the touch.
2. Transfer the bowl to the electric mixer and whip in high speed until light and fluffy and the bottom of the bowl doesn’t feel hot anymore. About 3-5 minutes.
3. Start adding the softened butter by the tablespoon. Keep adding more butter as it is incorporated into the meringue. Once all the butter has been added, add the lemon juice and the lemon oil. It might look as if the buttercream has separated. Don’t worry, keep whipping it because it will come together. Reserve until ready to use.
Chocolate Ganache
170 grams bittersweet chocolate (58% cacao)
170 grams heavy cream
1. Chop the chocolate into a bowl. Boil the cream and pour it over the chocolate. gently whisk the cream and the chocolate until the ganache is formed. Do not over whisk or it might separate depending on the type of chocolate you have used. We want the ganache to be liquid when we assemble the cake so I recommend making this right before or make it ahead of time and remelt it right before we are going to make the cake.
Lemon Simple Syrup
100 grams water
100 grams sugar
2 tsp lemon extract
1. Boil the sugar and the water until the sugar has dissolved. Remove from heat and add the lemon extract. Set aside.
Chocolate Glaze
110 grams bittersweet chocolate
110 grams coating chocolate
35 grams vegetable oil
1. Melt all the ingredients together over a double boiler and keep warm until we are ready to assemble.
Assemble the Opera Cake
1. The most important thing when you are building a cake with many components, is to set your self ready for success. That means, get your mise en place ready. Clean your work area of pots and pans and line all your components in front of you so you don’t go crazy and you work clean. Working clean is 75% of the success in your final product. I promise!
2. So get your sponges ready, the melted chocolate glaze, the melted ganache, the room temperature buttercream, the simple syrup, an offset spatula and a rubber spatula.
3.Place the first sheet of matcha sponge on your working surface. It will still have parchment paper on the bottom of the cake. Spread a very very thin layer of chocolate glaze on the top of the sponge cake. Spread the chocolate very thinly over the entire surface of the cake with a metal spatula (offset spatulas work best). let this glaze harden.
4. When the glaze has hardened (you can even put it in the refrigerator for a few minutes), turn it over onto a sheetpan that is also lined with parchment paper. So at this point, the glazed side of the sponge is down and you are left with the old parchment paper facing you. Remove this paper and discard.
5. Soak the cake with the lemon simple syrup with the help of a pastry brush. Then spread a third of the buttercream over the cake with an offset spatula. It is important to have an even layer because when we cut the cake, we want it to look clean and straight.
6. After the buttercream, pour a third of the ganache over the buttercream and spread it evenly. Place a second sheet of matcha sponge over the ganache making sure that the parchment paper that was on the bottom is now facing up. Remove the paper and brush the top of the cake with the lemon simple syrup. Spread half of the remaining buttercream over the cake, then spread half of the remaining ganache over it. Place the last sheet of sponge on top. Brush with simple syrup, spread the last bit of buttercream on top and finish with the ganache. There will be a total of 3 layers of sponge, 3 of buttercream and 3 of ganache.
7. Refrigerate the cake until the ganache sets. Then, flip the cake onto the back of another sheetpan so it is raised and we can glaze it. Spread a thin layer of melted chocolate glaze over the top and let the excess run off the sides. Refrigerate it again so the glaze sets.
Cut it into rectangles and decorate with a dusting of sifted matcha powder and gold leaf. This is optional, of course.
