As someone who usually makes a lot of birthday cakes for just about anyone I know, I bake at least 4-5 birthday cakes a month. Whenever my friends or family members celebrate their special day – I’m there with a cake, arranging a few candles for them to blow on.
This chocolate mousse cake is an all-time favorite that simply everyone loves. It’s made of a crunchy rice krispies base topped with coffee chocolate mousse layer and chopped dark chocolate for decoration. It’s gluten free and so delicious!
