The Fourth of July holiday is just around the corner and I am so excited to show you how to make this jaw-dropping watermelon layer cake dessert that is sure to wow your neighbors! If you show up at the BBQ with this beauty, I promise you will be the envy of the neighborhood and your plate will be empty when it’s over!

I just love the idea of making a cake made out of a watermelon! You won’t feel completely guilty eating a huge slice because it is all natural fruit! This is a great healthy alternative to your normal celebration cakes.

You can make this cake as simple or extravagant as you want. Be creative by adding a little bit of fruit garnish or go all out and add lots of colors. It’s really versatile for every occasion.

I wanted to create a unique red, white & blue dessert for the upcoming 4th of July holiday. I immediately thought of using watermelon. It is such a refreshing summer BBQ staple. I used skewers to add watermelon stars with blueberry accents and made silver ribbon pops for a firework display topper on this fun party dessert.
