Funfetti cake is one of those iconic recipes that makes people happy. Kids love the colors and sprinkles and adults love the trip back to memory lane when funfetti cakes were at nearly every birthday party.

Funfetti Cake

Salted Caramel Sheet Cake

I use the same cake recipe as my Salted Caramel Sheet Cake.

For this funfetti cake recipe, I wanted to use the recipe from my Chocolate Sheet Cake which I had already modified for my Caramel Sheet Cake. It’s such an easy recipe and turns out moist and perfect every time. I love this recipe because it requires no mixer, just a whisk, and it comes together in just a few minutes. Anything that’s easy and gets me in and out of the kitchen fast is a winner in my book!

Homemade Funfetti Cake

I thought the chocolate sheet cake recipe would make just enough for one 9-inch layer, but instead it was just enough for two 9-inch layers. I’ll have to go back to the drawing board and test the funfetti cake recipe—probably multiple times—in order to come up with the correct proportions for one 9-inch layer. It’s a tough job, I know, I know. For this funfetti cake, I used my Classic Buttercream Frosting but it would also be great with the Cream Cheese Frosting from my Red Velvet Cake.

Classic Buttercream Frosting
  1. In bowl of stand mixer and using the paddle attachment, cream butter until light and fluffy about 4 minutes. Add confectioner's sugar, a little at a time (about ½ cup), mixing on low until blended and then whipping on high for about 30 seconds each time. Add vanilla and pinch of salt and mix until blended. Add cream and mix on low until blended then whip on high until frosting reaches desired consistency.
  2. For softer frosting, you can add a little more cream. If you get it too soft just add a little more confectioner's sugar.
