Ingredients
- 1 seedless watermelon (you’ll only use the center)
- 1 seedless yellow watermelon (optional, for extra color)
- 1 1/2 cups mixed berries (blueberries, raspberries, blackberries)
- 1 kiwi, sliced into a decorative flower
- 1 peach or nectarine, thinly sliced
- Fresh mint leaves, for garnish
- Toothpicks (for securing fruit, optional)
How to Make Watermelon Fruit Cake
1. Prepare the Watermelon Layers
Start by cutting a thick, round slice from the center of a seedless watermelon. Remove the rind and any remaining white parts. Shape it into a smooth, round cake base. If you’re making a multi-tier cake, cut a second smaller round using the same technique. For added color contrast, use yellow watermelon for the top layer.
2. Stack the Cake Layers
Place the larger layer on a serving platter or cake stand. Center the smaller round on top. To help keep it stable, insert a toothpick vertically through the center. Be sure to remove the toothpick before serving or alert guests to its presence.
3. Decorate with Seasonal Fruit
Top your watermelon cake with a medley of fresh berries. Arrange kiwi slices or flowers, nestle in peach or nectarine slices, and tuck in fresh mint leaves for a pop of color. Use toothpicks to secure fruit if you plan to transport the cake or serve it outdoors.
4. Serve and Enjoy
Chill the finished cake until ready to serve. Slice like a traditional cake and enjoy this hydrating, wholesome treat!
Optional Additions
- Whipped cream or coconut whipped topping: For a more classic dessert flair.
- Shredded coconut: Adds tropical texture and flavor.
- Chocolate drizzle: Dark or white chocolate gives it a gourmet twist.
- Lime zest or honey drizzle: For extra brightness or natural sweetness.
- Edible flowers: For a stunning, decorative finish.
Storage & Make-Ahead Tips
- Best made fresh: Watermelon contains a lot of moisture, so this cake doesn’t store well for long.
- Chill before serving: Helps firm up the fruit and enhances the flavor.
- Do not freeze: The texture of watermelon changes drastically once frozen.
- Make a few hours in advance: Prepare the cake up to 2–3 hours before your event and keep it covered in the fridge.
Tips for Success
- Use cold, firm watermelon: Easier to slice and decorate.
- Dry surfaces slightly with paper towel: Helps prevent sliding.
- Choose symmetrical watermelons: For even cake layers.
- Get creative with your fruit selection: Grapes, melon balls, dragon fruit, or pineapple all work beautifully.
- Use cookie cutters for fun shapes: Cut star-shaped melon slices for a patriotic or festive theme.
FAQs
Can I make this a day ahead?
No. It’s best to assemble the cake on the day you plan to serve it to avoid sogginess.
What kind of knife should I use?
A large, sharp chef’s knife or serrated knife works best to slice clean, even rounds from the watermelon.
Can I use other melons instead of watermelon?
Yes! Cantaloupe, honeydew, and yellow watermelon all work beautifully for layering.
Can I make a mini version?
Absolutely. Use cookie cutters to create mini rounds and stack for individual servings.
