Ingredient Swaps and Additions

No watermelon juice? Use watermelon-flavored gelatin dissolved in water for an easy fix.
For a deeper flavor: Add a few drops of watermelon extract or concentrate to intensify the taste.

Add some crunch: A sprinkle of crushed freeze-dried watermelon or graham cracker crumbs adds a lovely topping twist.

How to Make Watermelon Cupcakes

1. Preheat Your Oven

Set your oven to 350°F (175°C) and line your cupcake tin with 12 liners.

2. Mix the Cupcake Batter

In a large mixing bowl, combine the white cake mix, watermelon juice or gelatin mixture, oil, and eggs. Beat for about 2 minutes until the batter is smooth. Add green food coloring if you want that signature “rind” hue.

3. Bake the Cupcakes

Divide the batter evenly into the cupcake liners. Bake for 18–22 minutes or until a toothpick inserted in the center comes out clean. Let them cool completely before frosting.

4. Make the Watermelon Frosting

Using a mixer, beat softened butter until creamy. Gradually add powdered sugar, mixing between each addition. Add watermelon juice or extract, a touch of vanilla, pink food coloring, and a pinch of salt. Beat until the frosting is fluffy and spreadable. Adjust sugar or juice as needed for consistency.

5. Decorate the Cupcakes

Pipe or spread the frosting on your cooled cupcakes. Finish by adding mini chocolate chips as “seeds.” (Pro tip: push them in slightly so they don’t fall off.)

What to Serve with Watermelon Cupcakes

Iced lemonade or mint tea: The freshness complements the fruity flavor.
Fresh fruit skewers: Keep the summery theme going!
Grilled pineapple or peaches: Trust me, it works.
A scoop of vanilla bean ice cream: Because why not?

Tips for Making the Best Watermelon Cupcakes

Don’t overmix the batter—gentle mixing = fluffy cupcakes.
Use gel food coloring for bolder color with less liquid.
Cool completely before frosting or your buttercream will melt!
Try a cupcake corer to add a watermelon jam center for a hidden surprise!

How to Store Watermelon Cupcakes

These cupcakes are best enjoyed fresh, but they’ll keep in an airtight container at room temperature for up to 2 days. For longer storage, refrigerate them (especially if it’s hot out), and bring to room temp before serving.

Freeze unfrosted cupcakes for up to 1 month. Thaw overnight, frost, and decorate when ready to serve.
Frosting can be made ahead and stored in the fridge for up to 4 days—just bring it back to room temp and re-whip before using.
