I never thought I’d put watermelon in a cupcake. It sounds odd—like moistening cake with summer’s most watery, crunchy fruit. But I kept thinking about how every bite releases this cool, slightly sweet juice that makes your fingers sticky. Now, imagine that inside a fluffy vanilla cupcake—bright pink, tender crumb, with tiny specks of juicy watermelon throughout.
This isn’t just a sweeter-than-usual treat. It’s a reminder that sometimes, ingredients you don’t expect can change everything. Watermelon feels like a portal back to childhood beach days, but baked into something you can hand out at a grill party or snack on during that fleeting moment when summer starts to wane.
I’ll admit, I was skeptical. But then I took that first bite—and the unexpectedness made me smile. Maybe it’s ridiculous, maybe it’s genius. Either way, it’s definitely worth a shot before watermelon season ends.
Watermelon Vanilla Cupcakes
Ingredients
Equipment
Method
- Blend the watermelon cubes in a blender or food processor until smooth, then strain to remove any pulp and seeds. Measure 1 cup of pureed watermelon and set aside.1 tsp vanilla extract
- In a mixing bowl, beat softened butter and granulated sugar together with an electric mixer on medium speed until light and fluffy, about 3 minutes. Observe the mixture turning pale and creamy.1/2 cup unsalted butter, 1 cup granulated sugar
- Add eggs one at a time, beating well after each addition, until the mixture is smooth and slightly increased in volume. Smell the vanilla as you add it to incorporate aroma.1 tsp vanilla extract, 2 large eggs
- Mix in the watermelon puree until fully combined, noting the pink hue spreading through the batter. The batter should look uniform and slightly thick.1 cup fresh watermelon
- In a separate bowl, whisk together flour and baking powder. Gradually add the dry ingredients to the wet batter, alternating with milk, beginning and ending with flour. Mix on low speed until just combined, being careful not to overmix.1 1/2 cups all-purpose flour, 1/2 cup milk
- Line a cupcake pan with liners and evenly divide the batter among the cups, filling each about two-thirds full. The batter should be pink and slightly airy.
- Bake in a preheated oven at 350°F (175°C) for 18–20 minutes, or until a toothpick inserted into the center comes out clean. The cupcakes will rise and turn golden at the edges.
- Remove the cupcakes from the oven and allow them to cool in the pan for 5 minutes, then transfer to a wire rack to cool completely. The cupcakes should be tender with a slight bounce when touched.
Notes
Maybe I’ll try swapping the frosting for a dollop of whipped cream next time. Or maybe I’ll just keep biting into these and pretend it’s perfectly normal. Either way, they’ll definitely get a double take.
