I found myself with left over truffle filling and wanted to find a good use for it. This is what I came up with, Neapolitan Cake. You will find the recipe in a printable at the end of this post.
Obviously, Neapolitan is chocolate, vanilla, and strawberry. When I got ready to mix this up I discovered that I had frozen mixed berries, not frozen strawberries. Instead of trying to sort out the strawberries I figured it wouldn't hurt to include the other berries as well. Well, it didn't hurt the flavor. It tasted great. But I did underestimate the strength of the blueberries in the mix. It was supposed to look more like this.
In a nut shell, I made a vanilla cake and divided the batter into three bowls. Then I turned one chocolate, one strawberry (or mixed berry), and left the last vanilla. Bake the batter in separate pans. I used a mini loaf pan. You will have about 2/3 cup of batter for each flavor. After baked and cooled, I stacked them using the truffle filling as frosting. This is a small recipe that will serve 6-8 people. You can certainly double the recipe for a larger cake.
