Have a slice of Watermelon - Cake!

I found this idea from a Livejournal community a year ago. I have a friend who loves watermelons, kind of like how my other friend loves cephalopods, and I knew as soon as I saw this cake that I had to make it for her. More than a year later, I finally got the chance to!

The inside looks like a watermelon as well! (Even though the chocolate chips sank to the bottom of each cake)
And it even tastes like watermelon!
The original recipe called for Watermelon Kool-Aid but considering I couldn't find any, so I threw together a different recipe from a modification of my Great-Granny's Lemon Cake recipe.

1 box yellow cake mix (I use the dry ingredients from this recipe instead)
1 pkg Watermelon Jell-O
1 cup water
4 eggs
3/4 cup oil
2 drops red food colouring
1/2 cup - 3/4 cup chocolate chips

Preheat oven to 350. Grease and flour cake pans. Mix cake mix with Watermelon Jell-O. Mix well. Add water, eggs and oil and beat with electric mixer for several minutes. Stir in food colouring and mix a little more. Carefully, but quickly, stir in chocolate chips, then immediately pour into cake batter pans. Sprinkle a few more chocolate chips on the top and then pop in the oven (again, quickly, you're trying to make the chocolate chips not sink to the bottom) Bake 30-40 minutes.

Ice with Pink and Green icing and top with more Chocolate Chips to make it look like a watermelon!
