"so pretty to serve and so easy to make. Finding the watermelon jello was the hardest thing about this cake. Kids love it!"

"I have mixed feelings about this recipe. The cake was delicious, but I couldn't do anything with it because it completly crumbled and fell apart. I made my own white cake, and then I followed the directions to frost it, and it was delicious. I made homemade cream cheese frosting. I give this a 3 star, because the cake crumbled at the slightest touch, but still tasted good by itself, and I like the creativity."

"I did this one in cupcakes and added mini chips to the batter. They were super cute and loved by all."

"I've made this cake twice for my daughter's birthday (she liked it so much she asked for it again). The first time I made it I had to use strawberry jello and it was great. Second time I used watermelon jello and it was just as good. Now my daughter is old enough to bake cakes by herself so maybe she will be the next in our house to attempt this."
