1/2 cup unsalted butter, softened
1 cups sugar
1 1/2 cups Gluten-Free all-purpose flour
Take a butter knife and swirl the chocolate cake batter into the vanilla cake batter. You don't want to over-stir here otherwise you'll lose the pretty marble effect.
Bake for 30 minutes or until a toothpick comes out clean.
You can create any frosting you might like to ice this cake with! Get creative and come up with your own flavor combination. I'm including a recipe below for a if you'd like to stick with the classics...a rich Creamy Vanilla butter cream. You can't go wrong with that!
