I get requests for this cake every BBQ. Tastes great and looks super cute. There are a couple differences between our recipes however. I add chocolate chips into the cake (as well as on top), make the white cake as directed (not adding any extra eggs, or oil), and I use 1 black cherry Koolaide mix instead of the gello.

cute idea. I needed a few more servings so made an extra round and sliced it in half. Frosted it the same way except for the straight edge mostly red. So it looked like an actual slice of watermelon. Then took a scalloped cookie cutter and made it look like a bite had been taken out.
