Recipe Ingredients for Watermelon Cake

When it comes to creating a Watermelon Cake, the selection of fresh ingredients is key. Each fruit brings its unique flavor and texture, working harmoniously together to create a refreshing dessert perfect for hot summer days. The star of this dish is undoubtedly the watermelon, providing a juicy base, while the cantaloupe and honeydew offer sweetness and a bit of crunch. The whipped cream ties everything together, creating a beautiful and delicious cake!
- 1 whole seedless watermelon: The centerpiece of your cake, providing a juicy and refreshing base. Choose a ripe watermelon for the best flavor.
- 1 whole cantaloupe: Adds a sweet, fragrant flavor that complements the watermelon beautifully.
- 1 whole honeydew melon: Offers a subtle sweetness and a lovely texture to the layers of the cake.
- 3 cups heavy whipping cream: For whipping into a fluffy frosting that adds richness to the cake.
- 1 teaspoon vanilla extract: Enhances the flavor of the whipped cream, making it even more delicious.
- 1/3 cup granulated sugar: Adds sweetness and helps stabilize the whipped cream.
- 1/4 cup blueberries (optional): A pretty garnish that adds a pop of color and flavor to the finished cake.
How to Assemble Watermelon Cake

Assembling a Watermelon Cake is as fun as it is rewarding! The process may seem intricate, but it’s straightforward and allows for creativity. Follow these steps to create a stunning centerpiece for your next gathering. Let’s dive into the delicious details!
- Start by placing a large, stable cutting board on your kitchen counter. Take your whole seedless watermelon and slice it into two “slabs” from the center, each about 1½ inches thick. Make sure to keep the cuts straight for a neat appearance.
- Next, slice one “slab” from the center of the whole cantaloupe, again about 1½ inches thick, and do the same with the whole honeydew melon. Reserve any excess melon for later use.
- Using a large round cookie cutter or a knife, carefully cut around the seeds and pulp in the centers of both the cantaloupe and honeydew slabs, discarding the seeds as you go. You want to create a hollow space where the seeds were.
- Now, stack your melon slabs on top of one another, starting with the largest diameter on the bottom. The watermelon should be the base, followed by the cantaloupe and topped with the honeydew.
- With a sharp knife, cut a circle around the melon stack, slicing just within the rind of the top slab. Make sure to achieve four equal slabs of melon without any rind left on them. If needed, work in batches, stacking only 2 to 3 slabs at a time, ensuring they remain uniform in diameter.
- In a stand mixer fitted with a whisk attachment, whip the heavy whipping cream until soft peaks form. This should take a few minutes of mixing.
- Once soft peaks form, add the vanilla extract and granulated sugar. Continue whisking until stiff peaks form, being careful not to over-whisk, which can turn the cream grainy.
- On a serving plate, place one watermelon slab and “frost” the top with a generous amount of the whipped cream you just prepared.
- Next, stack the cantaloupe slab on top of the watermelon and continue frosting between each layer until all the melon slabs are stacked. Make sure to mound a pile of whipped cream in the center to fill in the hole left by the seeds and pulp.
- Finally, place the last watermelon slab on top, mound the remaining whipped cream over it, and carefully spread it down the sides of the cake to achieve a smooth “frosting” effect.
- For the finishing touch, decorate the top with melon balls made from the leftover melons and sprinkle with the optional blueberries. Keep the cake refrigerated until serving.
Things Worth Knowing
- Choose ripe melons: When selecting your melons, look for ones that feel heavy for their size and have a uniform shape.
- Stabilizing cream: The sugar in the whipped cream not only sweetens but also stabilizes it, helping it hold up well in the fridge.
- Make ahead: You can prepare the melon slabs and whipped cream in advance, storing them separately until you’re ready to assemble the cake.
- Serving suggestions: This cake is perfect for summer picnics or parties, and it’s a great way to use up extra fruit.

Watermelon Cake
Equipment
- Chef's Knife
- Whisk
- Mixing Bowl
Ingredients
- 1 whole seedless watermelon
- 1 whole cantaloupe
- 1 whole honeydew melon
- 3 cups heavy whipping cream
- 1 teaspoon vanilla extract
- 1/3 cup granulated sugar
- 1/4 cup blueberries (optional)
Instructions
- On a large, stable cutting board or work surface, slice 1 whole seedless watermelon, making two “slabs” from the center, each about 1½ inches thick.
- Slice one “slab” from the center of 1 whole cantaloupe, 1½ inches thick. Slice one more “slab” from the center of 1 whole honeydew melon, 1½ inches thick. Reserve the excess melons for later.
- Use a large round cookie cutter or your knife to cut around the seeds/pulp in the center of the cantaloupe and honeydew slabs. Discard.
- Stack the melon slabs on top of one another, with the largest in diameter on the bottom.
- With your knife straight up and down, cut a circle around the melon stack, slicing just within the rind of the top slab. This should result in 4 equal slabs of melon, with no rind left on any of them. You may want to work in batches, stacking just 2 to 3 of the slabs at a time. Just be sure they are all the same diameter as the smallest slab.
- Whip 3 cups heavy whipping cream in a stand mixer with the whisk attachment until soft peaks form. Add 1 teaspoon vanilla extract and 1/3 cup granulated sugar and continue whisking until stiff peaks form, but do not over whisk.
- Place one watermelon slab on a serving plate. “Frost” the top with a bit of the whipped cream. Stack the cantaloupe slab on top, then continue stacking and frosting between each layer. After the cantaloupe and honeydew have been stacked, mound a pile of whipped cream in the center to fill in the hole left where you’ve removed the seeds and pulp.
- Stack the final watermelon slab on top, mound the remaining whipped cream, and spread it down over the sides of the cake to “frost” your cake.
- Top with melon balls (made with the leftover melon) and 1/4 cup blueberries.
- Keep refrigerated until serving.
Notes
- Tip 1: When choosing melons at the grocery store, look for larger cantaloupe and honeydew. Choose a full-size watermelon so you have enough fruit to cut two slabs from the center without too much size variation.
- Tip 2: The sugar stabilizes the whipped cream and holds up well when refrigerated.
- Tip 3: The whipped cream works well to frost the watermelon cake. Our cake was still intact, with the frosting looking as good as ever several days later in the refrigerator.
