I'm not crediting a source for this recipe because it's so ubiquitous at this point that I think everyone on Pinterest has either made it or eaten it at some point or another. I first had it at a friend's party in March and knew I needed to make it for my own party. It's very good. It tastes like Dunkaroos, if you remember those. Technically you could make it with any cake mix but the recipe calls for the Funfetti flavor. I've also seen varieties involving brownie mixes.
Anyway, it's good. I served it with some animal crackers and 'Nilla wafers.
Cake Batter Dip
1 package Funfetti cake mix
