This chocolate peanut butter mousse cake is one of my favorites; a Marye Audet original…and a classic. It all started when Ethan wanted a special cake for his birthday a few years ago. He wasn’t sure what he wanted but wanted something “different”. The chocolate peanut butter mousse cake was born…and it was an instant hit.

Deep, rich chocolate cake topped with a creamy, fluffy peanut butter mousse and then gilded with a layer of dense chocolate ganache. Perfection? You will have to decide. We thought it was.
This will make a 13 x 9 inch cake but should serve at least 24 people. Maybe more, depending on what your RFT ( rich foods tolerance) is.
Chocolate Peanut Butter Mousse cake should be kept in the refrigerator, but be sure to take it out about 30 minutes to an hour before you want to serve it.

Rich, dark chocolate cake topped with a cloud of peanut butter mousse and glazed with chocolate ganache. Think of it as a peanut butter cup on steroids

How often can you say YUM! before it gets old? Never, I hope!
Renee, I love everything about this cake…and I am working on a variation…stay tuned.
I’m making this today! A bit of advice — you may want to use pasteurized eggs in the mousse. Children, pregnant women, seniors and any who is sick is more susceptible to possible salmonella bacteria. I like to use the ones pasteurized in the shell because they are real eggs with no additives and taste exceptionally good.
Thanks for the great recipe. Maybe I’ll even try that caramel layer too!
Barb- I know a lot of people prefer the pasteurized eggs. I have my own chickens and I prefer to use the eggs from them.
OH MY GOODNESS! My family would flip over this! We all have pretty high RFT levels though and appreciate the combination of peanut buttery goodness with chocolate. Oh yeah, gonna have to try this one soon!
sherry, I am importing all my old recipes from Baking Delights.. so you will be seeing a lot of these old favorites.
