Cosmic Brownie Cake

It’s been a little while since we’ve done one of our throwback inspired posts so…. COSMIC BROWNIE CAKE! We’ve already made cosmic brownie pop tarts, eclairs and ice cream sandwiches but this cake is the easiest of them all. Because luckily for us… a sheet cake already looks 90% like a giant Cosmic Brownie!! And there really is nothing better than chocolate cake. So, let’s do this!
