Chocolate Almost Overdose Cake

chocolate overdose cake

Chocolate, oh how I can write pages and pages on you! My love! My life! I love chocolate cakes, so when I stumbled across this Chocolate Overdose Cake by Confections of a Foodie Bride, well…I just had to try it!. My first attempt went beautifully, but it was so rich with the brownie base and the brownie made it semi odd to cut into, so I decided to do a full chocolate cake instead. Now don’t get me wrong, the brownie base was still delightful, but it was too much chocolate(I didn’t think that was possible…) for me.

So I introduce you to a version of the chocolate overdose cake, which includes a rich chocolate cake, filled with a creamy chocolate mousse and topped with an oh so very lovely chocolate ganache.

Good luck on not eating all of the chocolate while you are baking!
