How to Make a Neapolitan Sheet Cake


We’re all familiar with the delicious chocolate, strawberry and vanilla flavors of Neapolitan ice cream. That classic combo was a childhood favorite that I specifically remember indulging in during birthday celebrations. We’ve taken those traditional flavors and made a Neapolitan sheet cake by alternating three different cake batters in a sheet pan so they would bake together, creating a fun chocolate, vanilla and strawberry Neapolitan sheet cake!

We topped our Neapolitan cake off with a buttercream frosting done 3 ways! This is really fun to make, it’s the same buttercream meringue base, divided into 3 bowls and each have their own special ingredient to make it strawberry, chocolate and vanilla flavored. It’s one of my favorite frosting recipes of all time!

The best part of this cake is that there are no dyes, just whole ingredients with naturally-colored strawberry cake and frosting! It’s not as pink as we’re all used too, but it tastes better and it’s natural!

This cake requires different batters. To make it easier, we made one vanilla batter and divided that in half to add strawberry preserves to one. Then for the chocolate, it’s a traditional chocolate cake (you can really use any chocolate cake recipe) and only half will go into the sheet cake. With the other half, we made chocolate cupcakes! It’s a win-win!

  9. Add in 1 cup strawberry preserves... the other cup will be for the frosting so save it.
  10. Stir the preserves until it's fully blended.
  11. Set the batter in the fridge and cool the chocolate cake to make the Neapolitan.
  12. Once all three cakes are finished, pour a line of the vanilla batter in the pan, then chocolate, then strawberry and alternate until the pan is filled.
  13. Bake in a preheated 350 degree oven for 30 minutes.
  14. Do you not over bake or they will become dry!
