Fresh Watermelon Cake {So Easy!}

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 real/fresh fruit cake and not a shaped/carved cake or a recipe with watermelon juice. 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 one single big cake, I made tiered mini cakes and decorated them with fresh edible flowers. I think they turned out gorgeous and are perfect for Summer parties.This Watermelon Ice Cream {2 Ingredients} and these Watermelon Cupcakes {Pull Apart Cupcakes} will round out your watermelon theme perfectly!

Key ingredients for watermelon birthday cake

  • Watermelon– Choose the ripest one you can find for the best flavor.
  • Flowers– Make sure they are edible.

3 Watermelon Cake Ideas

  1. The FIRST one is a baked cake, made with flour, sugar, eggs, watermelon juice e.t.c.
  2. The SECOND one is a decorated cake that looks like a watermelon, using fondant or buttercream.
  3. The THIRD one is a fresh cake that’s made by peeling the rind and carving the inside into the shape of a round cake and then frosting it in whipped cream or buttercream. That is the recipe in this post.

Cake decoration ideas

  • Fresh berries (strawberry, blackberry, raspberry, blueberry)
  • Pineapple slices
  • Kiwi
  • Grapes
  • Nuts
  • Dried fruits
  • Colorful frostings
  • Edible flowers

How to cut watermelon?

Use a very sharp long knife to cut 1 inch thick circular slices. Then use cookie cutters to cut the 3 different sized layers out of each large circular slice.

Variations for no bake fresh watermelon cake 

Make 1 larger tiered cake– Instead of these mini cakes. Then cut slices for each guest.

Use other fruit– You can follow the same instructions to make a cantaloupe cake or even a honeydew cake.

Make an 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.

Make a birthday cake– Decorate it with candies, sprinkles and you can even add a little birthday candle that kids can blow out.

Ice the whole cake– I only added a dollop of icing between eachse tier. You can go all the way and ice the entire cake with frosting such as How to Make Homemade Stabilized Whipped Cream, Marshmallow Frosting Recipe, or White Chocolate Buttercream Frosting.

Add frosting between each tier– Try these Brown Sugar Frosting {So fluffy!}, Chocolate Whipped Cream {3 Ingredients}, or How to Make Chantilly Cream {Creme Chantilly}.

Tips and techniques

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 and it will leave the plate very wet if you aren’t using icing.

You must use edible flowers– Ask your florist, if you are unsure. Some flowers are poisonous so better safe than sorry.

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, when adding strawberries.


Refrigerate– It should be stored in the fridge because it is fresh fruit and it can go bad in the heat.

Freeze– Do not freeze this because it will become a watery mushy mess upon thawing.
