This gluten-free Neapolitan cake recipe is a secret recipe that has been adapted to be completely gluten-free. The cake is made up of three layers: chocolate, vanilla, and strawberry. Each layer is made using gluten-free flour and other gluten-free ingredients. The cake is then frosted with a gluten-free buttercream frosting that is just as delicious as the traditional version. This gluten-free Neapolitan cake is perfect for anyone who has a gluten intolerance or celiac disease.
