Instructions

Step 1: Make sure your large watermelon is cold. Cut off both ends of your watermelon to create a flat, stable surface. Stand the watermelon on one of the flat ends. Using a sharp knife, carefully slice downward following the curve of the watermelon to remove all green rind and white pith. Rotate and continue until only pink flesh remains. Work slowly to minimize flesh loss and maintain a smooth, round shape.
Cut the peeled watermelon horizontally into 2-3 round layers (depending on desired height). The bottom layer should be the largest (approximately 8-9 inches in diameter), the middle layer 6-7 inches, and the top layer 4-5 inches for a tiered effect. Place watermelon layers on a wire rack set over a baking sheet. Refrigerate uncovered for 30 minutes. This allows surface moisture to evaporate.
Place your largest watermelon layer on a cake stand or serving platter. Insert 3-5 bamboo skewers spaced out evenly into the bottom watermelon layer, leaving about 1 inch protruding. This creates internal stability for a multi-tiered assembly. Carefully position the middle layer on top, pressing gently onto the skewers. Add the smallest layer on top if using three tiers.
Wash your berries and grapes, then pat them completely dry with paper towels. Get out your toothpicks and begin decorating, putting the berries and grapes on the toothpicks, then pressing gently into the watermelon surface. I like to start with strawberries, fill any gaps with smaller berries like blueberries, blackberries, and grapes. Refrigerate the completed watermelon fruit cake for 15 minutes before serving to firm up the structure.

Notes

Stacking Tip: If you're worried about the watermelon layers slipping, lightly dust the cut surfaces with cornstarch or arrowroot powder (about 1 teaspoon per layer) before stacking. This helps absorb excess moisture and creates a slightly tacky surface so the fruit sticks better and doesn't slide.
Temperature Is Everything: Keep your watermelon refrigerated until the moment you assemble. Cold fruit holds its shape much better, while room-temperature watermelon releases more juice and can lose structure within a couple of hours.
Skewer Tips: For taller, multi-layered cakes, use 4-5 bamboo skewers. This creates a sturdy internal support system for longer events.
Fruit Selection Matters: Choose firm, slightly underripe strawberries and berries. Softer, overripe fruit tends to release more juice and won't hold in place as well.
