I made this watermelon cake for my grandmother’s 79th birthday. They wanted a watermelon themed birthday cake. I used 2 boxes of cake mix, 1 – 13X9 cake pan and 1 – football cake pan. I cut the 13X9 cake in half, frosted them and put them on top of each other and then put the football cake on top. Shaped them into a round shape.
I then used white fondant on top of the cake. I then painted on the colors with gel coloring and clear vanilla. For the small slices, I used an extra half of another cake cut in half again to make triangles and covered those in fondant and painted those too. I also added chocolate chips to the cake to look like seeds. My grandmother loved it!
