Ingredients You’ll Need
-
Watermelon Cake:
- 1 whole seedless watermelon (about 5-6 pounds)
Whipped Cream Frosting:
- 2 cups heavy whipping cream
- 2 tablespoons powdered sugar
- 1 teaspoon vanilla extract

- 1 cup strawberries (halved)
- 1 cup blueberries
- 1/2 cup kiwi slices

How to Make Watermelon Cake Recipe
Step 1: Shape the Watermelon
Start by cutting off both ends of your watermelon so it stands upright on the cutting board. With a steady hand and a sharp knife, slice away the rind in gentle downward motions, following the curve of the fruit, until you’re left with a smooth, rounded cylinder. The goal: a sturdy, cake-like base with as even a surface as possible. Once your “cake” is formed, gently pat the whole thing dry with paper towels—this makes all the difference for a frosting that won’t slip!
Step 2: Whip the Cream
In a chilled mixing bowl, pour in the heavy whipping cream, powdered sugar, and vanilla extract. Beat the mixture with an electric mixer on medium-high until stiff peaks form—this takes a few minutes, but watch closely and don’t overmix. Fluffy, glossy whipped cream is the key to making this Watermelon Cake Recipe taste indulgent while staying extra fresh.
Step 3: Frost the Watermelon
Carefully cover the top and sides of your watermelon “cake” with the whipped cream, using a spatula or offset knife to smooth it as evenly as you wish. Don’t stress about perfection—any little swoops or swirls look charming and homemade. If the surface is still a bit damp, you can pat it a final time before frosting to help everything stick better.
Step 4: Decorate with Fruit
Now the fun part: crown your creation with halved strawberries, whole blueberries, kiwi slices, and any extra fruit you love. Arrange the berries and kiwi on top of the cake in circles, clusters, or dazzling patterns—use your artistic flair! Press on sliced almonds or sprinkle shredded coconut around the sides for extra pizzazz if you like. Add fresh mint leaves for an extra pop of color and aroma.
Step 5: Chill and Serve
For the best slice and flavor, place your decorated Watermelon Cake Recipe in the refrigerator for at least 30 minutes before serving. This brief chill sets the whipped cream and melds all the flavors together, rewarding your patience with refreshingly perfect slices. All that’s left to do is cut into it and listen to the delighted gasps!
How to Serve Watermelon Cake Recipe

Garnishes
A handful of fresh mint leaves, a delicate dusting of extra shredded coconut, or a sprinkle of colorful edible flowers can transform your Watermelon Cake Recipe from wonderful to unforgettable. Don’t underestimate the power of a simple garnish—it draws the eye and adds a lovely aroma with each bite.
Side Dishes
This cake is naturally light and hydrating, so pairing it with other fresh summer flavors is a hit. Think lemony iced tea, sparkling water with berries, grilled peaches, or a platter of sharp cheese and crackers. Each bite feels like a cool breeze on a hot day.
Creative Ways to Present
Cut your Watermelon Cake Recipe into traditional slices for a familiar feel, or try cubes skewered with extra fruit for a fun party snack. Stacking mini circular cakes for an individual dessert or building a “naked cake” by leaving the whipped cream mostly on top are sure to impress at any summer gathering.
Make Ahead and Storage
Storing Leftovers
If you find yourself with leftover Watermelon Cake Recipe (rare, but it happens!), cover the cake loosely with plastic wrap and store it in the fridge. It’s best enjoyed within a day so the whipped cream stays fluffy and the fruit remains vibrant.
Freezing
Freezing isn’t recommended, as watermelon becomes watery and the whipped cream changes texture after thawing. It’s a dessert meant to be savored fresh, right from the fridge—but that gives you a simply perfect excuse to make it disappear quickly!
Reheating
No reheating needed—just slice, serve, and delight in its cool, juicy freshness. If the cake has been in the fridge for a while, let it sit at room temperature for a few minutes to take the chill off, but don’t wait too long or the cream could become runny.
FAQs
Can I make this Watermelon Cake Recipe dairy-free?
Absolutely! Swap regular whipped cream for a coconut milk-based whipped topping or your favorite plant-based alternative. The cake will still be luscious, light, and just as festive.
How do I prevent my whipped cream from sliding off the cake?
Dry the cut watermelon thoroughly with paper towels before frosting—this step is key! Some folks even refrigerate the melon before assembling to help the cream adhere better.
What other fruits work well for decorating?
Feel free to experiment! Raspberries, blackberries, pomegranate seeds, and starfruit all look beautiful and add their own flavors to this Watermelon Cake Recipe. Just keep the pieces bite-sized for easy slicing.
Can I prepare the watermelon base ahead of time?
Yes—you can cut and shape the watermelon one day ahead, store it wrapped in the fridge, then frost and decorate just before serving for optimal texture and looks.
What if my watermelon isn’t perfectly round?
No worries! Even if your cake is a bit rustic, the whipped cream and fruit will dress it up beautifully. Remember: flavor comes first, and every Watermelon Cake Recipe is unique!
