I'm sure there are some flavor combinations you could throw together to make an interesting Watermelon Cupcake, but....I just went with vanilla. I tossed some chocolate chips in the batter to give each cupcake a 'seeded' look.
I iced these with strawberry icing, so they'd be a little 'fruity.' I decided to run the edge of the cupcake in green sprinkles (opposed to dying vanilla icing green), and then I tossed on a few mini chips for seeds. I think these are pretty fun. I don't think I'll win any prizes for these cupcakes, but....I'm not exactly planning on entering any contest in the near future, so....fun meets my standards for this kitchen exploration!
