CONFETTI CAKE! this month my sister is celebrating her 27th birthday, so she deserves a sprinkle cake. growing up funfetti cake mix was our all time favourite boxed cake, with rainbow bit vanilla frosting. thanks to molly yeh i was able to recreate it with a cake made from scratch, sorry betty. i like to call this a more grown up version of a boxed funfetti cake! is that such a thing? an adult sprinkle cake?! it is now. the recipe has been adapted from food52, where i aimed to make it slightly less artificial tasting, switching in pure vanilla extract and raw sugar. oh and what is that black dog like creature making an appearamce in my ingredient shot? that is my chihuahua pomeranian buddy holly, stealing the spotlight.

ingredients (makes two nine inch cakes)
