How do you make you a two layer cake with half white, chocolate, and strawberry homemade?
This is what I would do



you can buy cake pans with dividers in them, if you don't want to do that you could buy two cake mixes one a chocolate and one a white,prepare both mixes the way it says on the box.in one pan put half of the chocolate save the other half .Heres what to do with the second layer, with the vanilla cake mix you will also make the entire box,however after you have made the mix divide half of it in half so you will only be using a quarter of the mix in each pan,you can have quarter white and the other quarter add a little strawberry flavor and a little red food coloring when it is done you will have to quarters making the other half.You will not have to bake these quarters as long as the chocolate.You will have half of the chocolate mix and half of the white mix left that you can make cupcakes with.You will have two layers but three flavors.I would suggest frosting it with white frosting and a few fresh strawberries.good luck.
