I made some special devil's food chocolate cupcake for Valentine's day. I had filled the cups up half way and then put in a heart shaped marshmallow. However, they floated to the top during baking. Now this does end up being rather interesting. However, you don't get a nice dollop of marshmallow in the centre. So I frosted them and put another marshmallow on top.
Cute eh? The cupcakes... just a mix. The frosting is also store bought. Cheating is okay!
