Watermelon Cupcakes Recipe

Cupcakes bake super quickly and are perfect for all those summer parties!

Ingredients Needed for Watermelon Cupcakes

  • Butter: I recommend unsalted for most cupcake recipes.
  • Sugar: Because it’s cake! :)
  • Large Eggs: These hold the adorable cupcakes together.
  • Sour cream: Makes these extra moist. No one likes dry cupcakes.
  • Oil: For added moisture.
  • Milk: I use whole milk.

  • Vanilla extract: Do not use imitation!
  • All purpose flour: The foundation of every cupcake.
  • Baking powder: Makes the cupcakes fluffy and prevents them from becoming flat.
  • Salt: Brings out ALL the flavors.
  • Green gel food coloring: I prefer gel over liquid.

Ingredients for the Pink, Buttercream Frosting for Watermelon Cupcakes

  • Salted Butter. I prefer salted for frosting because of extra flavor.
  • Powdered sugar. Gives a powdery sweetness with a grainy texture.
  • Kool Aid Powder. If you don’t have kool-aid, watermelon flavored Jello is a good option too! Any pink or red fruity flavor does well in a pinch!
  • Red gel food coloring. You need to have this on hand to help you get the perfect pink frosting. Pink will work too, but if you use red, less food coloring is needed.
  • Mini, semi-sweet chocolate chips. These are the adorable, edible “seeds”

My husband just asked me, “Aren’t watermelons red, green, and black?”

Well, maybe in REAL life, but in a beautiful, colorful, cake decorating world I prefer pink and green — just because I can.

Watermelon Cupcakes Use Mini Chocolate Chips

So that’s why these watermelon cupcakes are pink and green — aren’t they cute?

Plus I love adding chocolate chips to anything!

Using these bright colors really contrasts the dark-colored chocolate chips to make the perfect picture watermelon seeds!

Can You Make Watermelon Cupcakes Ahead of Time?

One of our best party secrets is making and freezing food ahead of time!

Cupcakes and cookies are great for freezing ahead!

Don’t freeze the frosting ahead!

You can bake and freeze the cupcakes a few weeks ahead and make the frosting 1-2 days ahead.

That way on the day you want to serve the cupcakes you’ll just need to defrost, pipe, and decorate!
