Watermelon Cupcakes

These sweet and festive Watermelon Cupcakes are a summer time delight! They’re easy to make and swirled with pretty-in-pink frosting.

Green cupcake topped with white chocolate and pink watermleon frosting. chocolate chips sprinkled on top to resemble a watermelon.

Why these Cupcakes are Best

Nobody has to know these cute cupcakes start from a cake mix…and the flavor is so wonderful, adults love this festive treat as much as the kids.

I thought about making the cupcakes then just topping them with some watermelon flavored frosting. That would have been good but I wanted these to be AMAZING!

So, I turned to my trust friend: melted white chocolate. A thin layer of melted white chocolate on top of each cooled cupcake adds a bit of decadence and a pleasing white color to the watermelon cupcakes.

Finally, my favorite part: the FROSTING!

Watermelon Kool-Aid mix is my secret for giving fluffy buttercream its melon flavor.

Want to take the Watermelon theme a step further? Sprinkle some mini chocolate chips on top of the frosting. They look like watermelon seeds and tie the picture together. Also, I’ll never turn down a little extra chocolate!

Easy Watermelon Cupcakes

Tips & Tricks

  • If you can’t find Watermelon koolaid mix, you can order watermelon flavoring on Amazon!
  • No decorator bag? Spoon the frosting into a ziploc bag instead. Cut out a corner of the bag and pipe the frosting onto the cupcakes.

I must say, these tasted perfect.

The lime flavored cupcake was so slight, but just enough to give a good base flavor. The melted white chocolate hardened and gives a little texture to your bite. I loved these.

Summer Desserts

When it comes to summer food and beverages, you’re going to want to give this Watermelon Slush a try soon if you haven’t gotten around to it yet. I also love a bowl of Watermelon Peach Salsa with tortilla chips for summertime snacking.

Despite the way this post sounds right now, I promise you I don’t just eat Watermelon desserts in the summer. When the weather is warm, you can bet I’m making plenty of No Bake Lemon Cheesecake and Dole Whip too!

Watermelon cupcakes are sure to become as much a part of our summer dessert and snacking routine as a fresh cut Watermelon! I can’t wait for you to give these a try.

These sweet and festive Watermelon Cupcakes are the perfect summer recipe! Easy to make and delicious too!

These sweet and festive Watermelon Cupcakes are a summer time delight! They're easy to make and swirled with pretty-in-pink frosting.

Ingredients

For the cupcakes:

  • 1 box (18.25 ounce) white cake mix
  • 1 box (3 ounce) lime Jello (not sugar free)
  • 3 egg whites
  • ⅓ cup vegetable oil
  • 1 ¼ cup water

For the Topping:

  • 8 ounce white chocolate, melted
  • ½ cup butter, softened
  • 4 cups powdered sugar
  • ½ teaspoon Koolaid powdered mix (watermelon flavor)
  • 3-4 Tablespoons milk
  • ¾ cup mini chocolate chips

Instructions

  1. For the cake, add cake mix, jello, egg whites, oil and water in a mixing bowl. Beat 2 minutes until blended. Fill cupcake liners ⅔ full and bake in a 350 degree oven for 15-18 minutes. Do not overbake. Allow to cool completely.
  2. When cooled, spread melted white chocolate over top of each cupcake. While that sets, begin your frosting.
  3. In mixer, beat butter with powdered sugar, Koolaid mix and milk. Beat for about 3-5 minutes until fluffy and smooth. Using a decorator bag and tip (I used 6S), pipe frosting on each cupcake and immediately sprinkle with chocolate chips. ENJOY!

  3. LOVE how you used koolaid to flavor (and add color) to the frosting. That opens up so many possibilities! Thanks for the inspiration. 🙂

    1. Can’t be responsible for that one, I’ve seen it before. Most times it’s been inside a strawberry cake decorated with green frosting. I just went the other way around!

  4. these are just too cute!! i saw them and it actually brought a smile to my face 🙂

  5. These are so pretty! What a wonderful treat to make for my next picnic. Thanks so much for sharing at Mix it up Monday 🙂

  6. I LOVE these! These are adorable. We love watermelon, it’s just what you eat in the summer, these cupcakes are perfect. I love Kings Island! Lots of memories there. I actually live “just down the road” in Batavia. Hope to get up to the waterpark this summer!

  7. These look absolutely superb and i bet they are very refreshing. Going to give these a try at the weekend.

  8. Too cute and great idea with the watermelon-cherry Koolaid mix – now THAT will make the flavor pop!

  9. How adorable are these? I bet these would get my kid to eat watermelon, ha. Such a great idea Aimee!

    1. Cupcake Project has quite a few wacky meat-including cupcakes, even one with spam! {which is supposedly good}
      though actually, I’m that picky vegetarian, too… 🙂

  10. Those are so very cute!!! I have a small confession…I don’t really like watermelon in any form! But for you I would try the cupcake…maybe my taste buds have changed? With all the chocolate and lime, I bet I would like it!! Funny thing is that I love the smell of the yankee candle watermelon scent:-)
