This months Daring Bakers challenge was an opera cake. The opera cake sounded pretty challenging having no less that five different components. The components included a cake, a syrup, a buttercream, a ganache and a glaze. The thing that I liked most about the challenge was that we were allowed to choose the flavours in the cake as long as the colours remained light. I decided to go with one of my current favorite dessert flavour combinations, green tea and white chocolate.
Note: I halved all the recipes for all components as I did not want such a large cake.
Green Tea Cake
The first component of the opera cake was of course the cake. The cake sounded pretty interesting because it used ground almonds. I wanted the cake to have a green tea flavour and have a green colour so I added some matcha. The cake came together pretty easily and it had a really nice shade of green.
Green Tea Syrup
The cake in the opera cake needed to be moistened with a syrup. The syrup was just a simple syrup with some added flavour. I remembered that I had seen some green tea liqueur and I though that it would go well in the syrup. The green tea liqueur was a nice dark green and it tasted like green tea and had hints of spices and berries. It added a nice aroma to the syrup and the opera cake.
Green Tea Buttercream
There was a bit of confusion with the recipe for the buttercream and in the end I was not sure what recipe to use so I used the recipe from the Perfect Party Cake challenge. I decided that I wanted the buttercream to be green as well so I added some matcha to it. The first time that I made buttercream it did not work out too well. The second time I got a nice finished product but it took about 20 minutes of beating the cream by hand. This time everything came together easily with less than 5 minutes of beating by hand in the final step. Given the amount of beating in the other components I was a bit relieved. The buttercream ended up with a nice light green colour and tasted great. Must keep fingers out of butter cream.
White Chocolate Ganache
The ganache was the first of the white chocolate components of the opera cake. I had made chocolate ganache before but I have never tried folding in whipped cream in addition to melting the chocolate into cream. The whipped cream left the chocolate light and fluffy. Unfortunately it also left the ganache a bit runny and a lot of the ganache ran out from the middle layer of the cake. Putting it in the fridge for a while fixed that problem though.
White Chocolate Glaze
The opera cake was topped with a simple white chocolate glaze that came together easily.
Assembling the Opera Cake
Assembling the cake was the funnest part of the challenge. After the cake was assembled I chilled it in the fridge and then trimmed the sides to get nice and straight edges.
Overall the opera cake was not too difficult to make and it turned out really good! It tasted great and it disappeared quite quickly! The slight bitterness of the green tea tempered the sweetness of the white chocolate nicely. The cake was nice a moist and light and creamy at the same time. I really enjoyed the opera cake challenge.

darn, we are totally on the same page. i did green tea opera cakes too.
Rob says
I have to say, of all the opera cakes I have read about on the blogosphere, this one stands out by a mile. The idea of using green tea as a flavouring here is novel and a winner and I suspect tempered the sweetness of the whole cake somewhat too.
Great blog too by the way!
Alli says
This looks great! I have see quite a few recipes with green tea but never tried baking anything with tea. I definitely like the idea of it with chocolate!

Great recipe. I just used the cake for my attempt;

hey this cake look amazing I have bought all the ingredients but could not find the Green tea liqueur anywhere, do you have any idea's of what i could use instead

Kevin says
Anonymous: You have a number of options including simply skipping it entirely or replacing it with another liqueur such as a white chocolate or a vanilla or you could mix a bit of matcha into the syrup.

I've been wanting to make this cake for a while. I've learn how to properly beat egg whites, but should I buy ground almonds or grind them myself by blanching, toasting and grinding them? Maybe they will be too coarse and will stop the cake from rising.
Kevin says
Anonymous: If you have a good food processor or blender you should be able to grind your own, otherwise store bought can also be handy.
Anonymous says
this recipe looks incredible! if you don't mind, im going to be using it to make for a food competition at my school, but i have a question. for the almonds, is that a cup of the almonds after they are ground? or do i take a cup of blanched almonds, and then grind that and put whatever measure is left over into the mix?
thanks so much, and i can't wait to make this delicious cake! =]
Kevin says
Anonymous: That is one cup of almonds after they are ground. Sorry for he confusion.
Jane Veronis says
I was just wondering what I could use as a substitute if I can't find Green Tea Liquer. (I live on an island in SPain, no hope of finding that here!)
