Also making confetti cake is so easy. Just throw sprinkles into the cake batter XD

I made a chocolate meltdown cake brownie thing once.

Chocolate Cake
Brownies
Chocolate Frosting
A Bar of Chocolate
Chocolate Ice Cream
Hot Fudge

First bake a chocolate cake and brownies, making them thinner then usual. When those are baked, take the Bar of Chocolate, smash it into pieces, and mix it into the frosting. Frost the cake, then put the Brownie right on top, then frost that as well if desired. Cut, microwave for 30 seconds, they add a generous scoop of ice cream. Top that with some hot fudge and you have an explosion of chocolate.
