Learn how to make a quick and easy watermelon cake recipe that’s fresh, no bake, healthy, beautiful and perfect for Summer parties, birthday parties or even weddings.

I want to CLARIFY that this is a fresh watermelon cake/ real watermelon cake and NOT a watermelon shaped cake or a watermelon cake recipe from scratch.

The easy cake trend has been around for a few years now but I wanted to do something different with that concept.

Instead of making a big watermelon cake, I made tiered MINI watermelon cakes and decorated them with fresh edible FLOWERS. I think they turned out GORGEOUS and are perfect for Summer parties.

Tips for no bake watermelon cake recipe:

  • Make sure to pat the watermelon DRY with paper towels to get rid of excess juices because if the watermelon is too “wet,” icing won’t stick to it properly.
  • You must use EDIBLE flowers. Ask your florist, if you are unsure.
  • You can make 1 big cake instead of these mini cakes.
  • ANY shape of cutter can be used. Metal cutters create a sharper cut compared to the plastic ones.
  • If you are decorating with other smaller fruits, use TOOTHPICKS to stick them securely into place. I use this trick to make my kiddo’s favorite strawberry watermelon cake.
  • You can also follow the SAME instructions to make a cantaloupe cake or even a honeydew cake.
  • To make watermelon ice cream cake, use ice cream frosting OR cover the cake in partially melted ice cream. Keep the cake frozen until you are ready to serve.
  • To make watermelon birthday cake/ watermelon smash cake, decorate with candies, sprinkles and you can even add a little birthday candle that kids can blow out.
