Instructions
Preheat and Prep: Preheat your oven to 350°F (175°C). Line a 12-cup muffin tin with cupcake liners (green liners enhance the watermelon rind theme).
Mix Dry Ingredients: In a medium bowl, whisk together 1 ½ cups flour, 1 tsp baking powder, ¼ tsp baking soda, and ¼ tsp salt. Set aside.
Cream Butter and Sugar: In a large bowl, use an electric mixer to cream ½ cup softened butter and ¾ cup sugar until light and fluffy (2–3 minutes).
Add Wet Ingredients: Beat in 2 eggs one at a time, then mix in 1 tsp vanilla extract and ¼ tsp LorAnn Super Strength Watermelon Flavoring.
Combine Wet and Dry: Gradually add the dry ingredients to the butter mixture in three parts, alternating with ½ cup milk (start and end with dry ingredients). Mix until just combined to avoid overmixing.
Color the Batter: Add 4 drops green gel food coloring and mix until evenly distributed for a rind-like hue.
Scoop Batter: Using a medium cookie scoop (2.7–3 tbsp, #20 or #24), divide batter into liners, filling each about ⅔ full. Gently tap the tin to settle batter and remove air bubbles.
Bake: Bake for 18–20 minutes, or until a toothpick inserted in the center comes out clean. Cool in the tin for 5 minutes, then transfer to a wire rack to cool completely.
Prep Frosting Juice: Blend ~1 ½ cups seedless watermelon chunks and strain through a fine mesh sieve to get 3 ½–4 tbsp juice.
Make Frosting: Beat ½ cup softened butter until creamy. Gradually add 2 cups powdered sugar, then mix in 3 ½ tbsp watermelon juice, ½ tsp vanilla extract, pinch of salt, and 4 drops red gel food coloring. Add up to ½ tbsp more juice if desired, adjusting with 2 tbsp powdered sugar if too thin.
Pipe Frosting: Transfer frosting to a piping bag with a Wilton 2A tip. Pipe smooth swirls onto cooled cupcakes.
Decorate: Sprinkle 6–10 watermelon seed candies (preferred for authentic flavor) or mini semi-sweet chocolate chips on each cupcake for a “seed” effect.

Notes
LorAnn’s Flavoring: Use exactly ¼ tsp for a balanced watermelon taste. It’s very potent, so don’t overdo it! Available in 1 dram (~1 tsp) or 1 oz bottles at Amazon or LorAnn’s site.Watermelon Seed Candies: These tiny, black, watermelon-flavored candies from Bulk Candy Store add authentic flavor and a perfect “seed” look. Mini semi-sweet chocolate chips are an accessible substitute but lack the watermelon taste (candies are preferred).Scoop Tip: A medium cookie scoop (2.7–3 tbsp) ensures uniform cupcakes. Pro Tip: Tap the muffin tin before baking for a smooth, even texture.Frosting Consistency: If 4 tbsp watermelon juice thins the frosting too much, add powdered sugar in 2 tbsp increments to keep it pipeable.Storage: Store in an airtight container at room temperature for 2 days or in the fridge for 5 days. Serve at room temp for best flavor.
