HOW TO MAKE OUR FRESH WATERMELON CAKE
With just 5-step instructions and a 10-minute prep time, this recipe couldn’t be quicker or easier to put together. And you can have some fun decorating your cake however you like, for any occasion!
- Whip together heavy cream, powdered sugar, lemon juice, and cinnamon in a chilled bowl until stiff peaks form.
PRO-TIP: Cream whips best when it’s cold, so we recommend using a chilled bowl to make it. Just pop it in the freezer for about 15 minutes prior to making it! - Cut the top and bottom of the watermelon to create flat surfaces on both ends.
- Trim off all skin and shape the watermelon into a cake. Pat the watermelon dry (this is super important or the whipped cream topping won’t stick.)
Pro-tip: You should have quite a few scraps of watermelon from trimming the cake down. Feel free to chop it up to snack on later or add it to a fruit salad. - Coat the watermelon in whipped topping.
Pro-tip: If you have extra whipped cream after decorating the cake, use it as a fruit dip for any extra fruit left over (or to eat alongside the watermelon scraps). - Decorate with raspberries, blueberries, and strawberries.

VARIATIONS / OPTIONS / ADD-INS
- TOPPINGS: You can have a lot of fun with the topping on this cake. You can switch out the fruit entirely. Or, you can add ingredients like shredded coconut or crushed almonds. You could also drizzle this cake with chocolate, or add sprinkles to jazz it up. Really, the sky’s the limit when it comes to the toppings on your watermelon cake.
- WHIPPED CREAM: If you prefer, you can simply use a store-bought whipped topping for your cake (but we really prefer the homemade!). You could also leave the whipped cream off altogether and decorate your cake without.

Fresh Watermelon Cake
Ingredients
- 2½ cups cold heavy whipping cream
- ½ cup powdered sugar
- 2 tbsp lemon juice
- 1 tsp cinnamon
- 1 seedless watermelon
- ½ cup raspberries
- ½ cup strawberries sliced or halved
- ¼ cup blueberries
Instructions
- Refrigerate the metal bowl you will use for mixing for at least 10 minutes. Or chill it in the freezer for five minutes. This will make it easier to whip your frosting.
- Make the whipped cream by using a mixer to whip the heavy cream, powdered sugar, lemon juice, and cinnamon in the cold bowl until it forms stiff peaks, about 3-5 minutes. Make sure the peaks are as stiff as you can make them. Refrigerate immediately and set aside for now.
- Cut the top and bottom of the watermelon to create even flat surfaces on both ends. The watermelon should be able to stand upright now. Trim off all the skin on the watermelon.
- Shape the watermelon into a cake form by trimming the sides into straight lines and cutting more off the top and bottom.
- Pat the watermelon dry with a paper towel as thoroughly as you can.
- Coat the entire watermelon with previously made whipped cream.
- Decorate with raspberries, blueberries, and strawberries. Refrigerate until ready to plate and serve.
