Donut Cake | Flour Shop In NYC

To bake the cake, divide the undyed batter between 2 halves of a greased 8-inch round donut cake pan or 2 smooth 8-inch Bundt pans. Bake both cakes for 15 minutes, then turn and bake for another 15 minutes. Cool according to Vanilla Layer Cake instructions. 

When the cake has cooled, make the frosting: Dye half of the frosting for the “icing” on the top of the donut: pink, brown, or blue. Remember to start with 1 drop food coloring, mix it in, and add more until color is as desired. (You’ll have plenty of white left over for filling the layers, adding squiggles, and making more "icing" if you need it.)

Build your donut: Cover the top of the bottom half of the fully cooled cake with a thin layer of white frosting, then add the top layer. Voila: donut. Spread colored frosting on just the top of the donuts. You don’t want it to go too far down the sides or else it won’t look like a donut. Frost the tops and add sprinkles as desired.
