    watermelon cupcakes

    I recently shared a recipe for a watermelon cake but sometimes it just easier to make and serve cupcakes than it is to serve a cake. So I decided to make these watermelon cupcakes that are perfect for all of your summer celebrations!

    How To Make Watermelon Cupcakes

    watermelon cubes in blender

    Step One: Watermelon Puree

    You'll need one cup of watermelon puree/juice for this recipe so cut up about 1 1/2 cups of watermelon and puree it in the blender or food processor.

    Here's how to cut a watermelon, as well as some very cool watermelon slicers.

    Step 2: Cake Batter

    For the watermelon cake batter, the ingredients are similar to those on the cake mix package but instead of water this recipe uses the pureed watermelon.

    To intensify the watermelon flavor, I added a packet of watermelon Kool-Aid! If you can't find watermelon Kool-Aid in your area, you can use watermelon Jello or even LorAnn watermelon flavoring.

    Or skip the added flavor and just use the watermelon puree.

    Divide the batter between two cupcake pans with liners to make 24 cupcakes.

    baked cupcakes

    Bake the cupcakes, remove them from the pans and cool completely on a rack.

    Three Color Buttercream Frosting

    pink, green and white buttercream frosting

    Divide your buttercream frosting equally between three bowls. Tint one bowl pink, one bowl green and leave one bowl of frosting white.

    three colors of frosting in one bag

    Put each color of frosting in a separate pastry bag and cut the tip. Then, put a pastry tip in an empty bag and put all three of the frosting bags into it.

    By putting all three colors in one bag you get a beautiful swirled frosting when you pipe it onto the cupcakes.

    Recipe Tips

    1. Can I make these cupcakes without the watermelon puree? Yes, you can substitute one cup of watermelon puree with one cup of water.

    2. I can’t find watermelon Kool-Aid. What can I use as a substitute? If you can't find watermelon Kool-Aid in your area, you can use watermelon Jello or even LorAnn watermelon flavoring. Or skip the added flavor and just use the watermelon puree.

    3. Can I make a cake instead of cupcakes? Yes! Check out my Watermelon Cake recipe for exactly how.

    4. How should I store the watermelon cupcakes? Store them in an airtight container in the fridge. They should last 2-3 days.
