I like marble swirls, especially of those marble cakes, and been wondering whether it'd look nice through cupcake paper cups too. So I baked some.
I picked the recipe from Martha Stewart in the book "Martha Stewart's Cupcake". In the original recipe it is suggested to serve these cupcakes 'naked' with a lightly springkle of icing sugar. But I'd like to utilize leftover strawberries. So I made extra strawberry buttercream to give those cuppies a little 'icing on the cake' ;)
