Prepare the cake batter in a large mixing bowl using a hand mixer or stand mixer according to the directions on the box substituting buttermilk for water and butter for vegetable oil and using egg whites.

Bake until a wooden pick or cake tester inserted into the center of the cake comes out clean, about 30 minutes.

Allow to cool completely on a wire rack in pan.

Hint: Allow the cake to cool completely to room temperature before frosting. This is important because while the cake is warm, the frosting will tug at the surface and melt into the cake.

Frosting

🍽 Equipment

The following items will help you to make this recipe successfully.

🍱Storage

Funfetti Cake with Frosting can be stored at room temperature in a cake holder or carefully covered with plastic wrap. It will be fine for up to 4 days or so. I like to bake this cake in a Wilton Cake Pan with Lid - the lid snaps on easily and helps to keep the cake fresh.

This cake freezes well for up to 4 months when stored in an airtight container.

💭Top tip

I like to put a pat of butter on some waxed paper and grease my pans and dust lightly with flour before baking. It works just as well as store bought baking spray but is much less expensive!
