Chocolate Mousse Cake

Chocolate Mousse Cake sliced

When I made this Chocolate Mousse Cake originally it was ALL CHOCOLATE of course!

But something is happening to me in my old age (well…lots of things are happening to me, but let’s not even go there!)

My tastes are changing (among other things LOL) and I am branching out to include vanilla in some of my dessert choices!

Let me just say I am so happy I did!

The combination of this yellow cake with the chocolate mousse and ganache is out of this world!

It didn’t take long to gobble up this entire cake (yes I shared!) and then made it again with my new recipe for Butter Cake and let me tell you- WINNER WINNER One More Time!

Check out What is Cake to get a better idea of how to pair your cake choices with your filling choices and icings as well.

The Butter Cake is best served at room temperature it was no problem to let this cake set out on the counter for about an hour to hour & half before serving and it was absolutely perfect!

So although in the video I mentioned to use the Yellow Cake…I’m now thinking VANILLA BUTTER CAKE all the way!

Of course Chocolate Cake is a no-brainer, like DUH! how amazing will that combination be! Death by chocolate here we come!

    How do I shave my chocolate to make it look like yours. It comes out really small and just kind of looks like I put it through a blender. It does not make curls like yours does and I am using a veggie peeler and sometimes even a knife love from North Carolina

          Curling chocolate with a vegetable peeler is best achieved when the chocolate is warm and slightly softened. When cold it becomes brittle and will not curl.

          If you are holding a piece of chocolate in your hand while curling the heat from your hand will cause the chocolate to become too soft to work with. If this occurs simply slip the chocolate into the frig or freezer for a minute or so the firm up.

          Once the curls are made slip the container holding them into the frig for a few minutes to firm up. Much easier to handle that way. :)

    My name is Methos and I’m from Denmark. This is the first time I write a message though I followed you regularly from your previous blogs. I was kind Of sad when I realized you stop sending me updates because I learned a lot from your way of instructing. You are very clear and so easy to understand your explanations. It is so obvious that you really put your heart into baking and have the desire to Teach others. Just want to thank you so much for not tiring out of sharing with us your fantastic skills. You are very much appreciated.
