  • This cake has a nice soft and light crumbs, thanks to the volume that the egg white added. What I like the most about this cake is that it is not too sweet. The chocolate cake and the white chocolate mousse perfectly complemented each other. The frosting so pillowy fluffy and soft, and not too sweet.

Use it to make a trifle

If you have any leftover, you can use the cake to make a trifle. A trifle is basically a cake or some sort of soft cookie layered in a trifle glass with cream, fresh fruits, custard cream and chocolate syrup. I used my leftover cake and custard cream to make this simple trifle. Layered the cake with custard cream, whipped cream and Raspberry.

How to Make This Cake

Make the White Chocolate Mousse

This is a a 2 ingredients white chocolate mouse. You will need whipping cream and good quality white chocolate bar. I recommend chocolate bars rather than chocolate chips. I normally use Lindt or the baking chocolate I buy in Sinfully The Best, a chocolateire shop where I live. Use what you have in your area. Chop the chocolate as fine as possible for easy melting. Transfer this to a microwave safe bowl and add 1/3 of the of the cream. Microwave in 30 seconds interval, stir after each interval. Repeat until the chocolate is fully melted then pour the remaining cream. This mixture need to cool, like really cold so that it whips better. refrigerate. This will take awhile, depending on how cold your refrigerator. Approximately 1-2 hrs. I suggest doing this first before anything else so that it is already cooling while you bake the cake.

Make the Chocolate Sponge Cake

For the main cake, we are making chocolate sponge cake. Sponge cakes are light, airy and delicate cakes. Sponge cakes relies on whipped egg white for volume and rise. Basically, this involves whipping the egg whites and sugar until stiff peaks.

The add the chocolate flavor, we are blooming (or dissolving) the cocoa powder with the warm melted butter. This process will enhance help dissolve the cocoa powder better and helps release a more intense chocolate flavor. The addition of coffee here will not affect the taste. The coffee also helps bring out the chocolate flavor in the cocoa powder.

The rest of the step is just adding the egg yolk, milk and dry ingredients and mixing until just combined. Add about 1/4 of the the whipped egg whites and fold until no more streaks of egg white is visible. Then pour the chocolate mixture to the remaining egg white mixture and gently fold until no more streaks of egg white is visible. It is that easy! Bake it, let it cool. You now have the base sponge cake that you can use and frost however you like. remove the cake from the pan after 5 minutes. Do not leave it cooling in the pan as steam will make the sponge wet. Cool the cake in a cooling rack. The cake need to be really cool before you ad the frosting otherwise the mousse will melt.

Decorate the Cake

You can decorate the cake to your preference. What I did was add the mousse frosting in the middle of the cake and on top. I decorated the cake with white, dark and semi-sweet chocolates. Fresh fruits are good idea too. Raspberry, Strawberry or mix or berries. Shaved chocolates are great idea too, or a drizzle of chocolate ganache or caramel sauce is a good option too.

Tips to Remember

  1. Use room temperature Eggs: This is common thing to remember when using eggs for baking, even more if there is a creaming process involved. Room temperature eggs mix well and cream better than cold egg. Take the egg out at least 1 hr before using it. If you are baking the cake the following day, you can take the egg out overnight for use the following day.
  2. Bloom the Cocoa Powder: This means dissolving the cocoa powder in a hot liquid, in this case, butter. Blooming helps enhance the chocolate flavor of the cocoa powder.
  3. Make Sure the White Chocolate Mousse if Cold: For the white chocolate mousse to whip and be light and fluffy, the mixture MUST be cold. Be patient and wait for it to be cold before whipping.
