For the Cake Base
- 12 lb seedless watermelon
- Fresh mint sprigs (for garnish)
For the Frosting
- 3 cups heavy cream (chilled)
- 1/3 cup sugar
- 1 vanilla bean, split and scraped
- 1/2 teaspoon cream of tartar
- 1 pinch fine sea salt
- Prepare the Watermelon Structure: Start by cutting flat, even ends off the watermelon and set them aside as decorative toppers. Stand the watermelon upright and carefully slice away the green and white rind on all sides to create smooth, clean surfaces. Shape the watermelon flesh into a cylindrical cake form with flat top and bottom; this is easiest to do while the watermelon is whole and stable.
- Make the Stabilized Whipped Cream: Pour the chilled heavy cream into a cold bowl and beat on high speed with an electric mixer until soft peaks form (about 2-3 minutes). Add cream of tartar and a pinch of fine sea salt to stabilize the cream and prevent graininess. Continue beating, slowly add sugar, then incorporate the vanilla bean seeds. Beat for an additional 3 minutes until stiff peaks develop, ensuring a stable whipped cream that holds up well.
- Assemble and Decorate the Cake: Pat the watermelon cylinder dry thoroughly with paper towels to remove moisture for better cream adhesion. Place the watermelon on a serving plate. Using an offset spatula or knife, evenly spread the whipped cream over the top and sides for a smooth finish. Use a melon baller to scoop decorative watermelon balls from the reserved ends and arrange them on top of the cream. Garnish with fresh mint sprigs for color and freshness.
Notes
- Thoroughly dry the watermelon surface before applying whipped cream to prevent sliding.
- Do not over-whip the cream to avoid grainy or butter-like texture; stop at stiff peaks.
- Chill the watermelon after shaping and before frosting to help the cream adhere better.
- Assemble the cake close to serving time to avoid the whipped cream weeping or sliding off.
- Seedless watermelon is essential for ease of eating and clean presentation.
- Substitute coconut cream for heavy cream for a dairy-free option.
- Vanilla extract can replace vanilla bean if necessary (1-2 teaspoons).
- Powdered sugar can replace granulated sugar for a smoother texture.
- Fresh berries or lemon sorbet pair well when serving.
