Watermelon Cupcakes: Cupcake Tuesday

Welcome to Cupcake Tuesday! I’m so glad to have you! I have updated the Cupcake Heaven page, there are over 100 designs and recipes! Check it out!!

Did you see all the fun cupcakes last week on Cupcake Tuesday? Lots of great ideas!

Well, I don’t know about you, but Summer is going by WAY too fast! My boys only have 2 weeks left before school starts, and Nick has already started Football practice. I’m actually one of those Moms that don’t like when the kids go back to school, I love them being home {most days}, although I do like the schedule that the school year forces upon us.

But…we aren’t to school time quite yet! I’m holding onto every last day of Summer, especially with these Watermelon Cupcakes. By adding watermelon flavored Jello-O, it gives the cupcakes a nice hint of watermelon, but not too overpowering.

See the cool cupcake wrappers? I made them…on my new Silhouette machine!! Yep, and you can enter to win one too! Stop back on Thursday for the BIG Giveaway!

Now, let’s talk cupcakes…by adding a few drops of pink coloring and some mini chocolate chips to the cake, you can create fun, Summer Cupcakes. I frosted them using a Round #12 tip, rolled in Pink Sparkling Sugar and topped with a few more mini chocolate chips.

You could also leave out the chocolate chips and they would be a fun pink cupcake for a little girls birthday party.

Although it’s not a juicy slice of watermelon, the inside of the cupcake will definitely resemble one.


  1. Mine taste fine but they didn’t puff up like normal cupcakes…. don’t know why

    1. Hi Maddie, sometimes it’s because of the oven and over beating the batter. Have you had trouble with other cupcakes doing the same or just this recipe?

  2. Doesn’t say how much buttermilk getting ready to make these with a bunch of seniors need asap

  3. I tried this recipe today and it tastes great. My mother loved it so I’m going to take some to work tomorrow and see how it goes!

  4. I just tried this recipe today, and not sure why but it did not work. Does not taste like watermelon at all. I bought everything that you listed, and prepared it just as it was instructed. Not sure where I went wrong. Weren’t they supposed to taste like the jello flavoring?

    1. Hi Jenna, I’m not sure why they didn’t taste like watermelon, they did to me. Yes, the jello is where the flavoring comes from.

      1. Thank you so much for replying! Perhaps I just need to try baking them again, but mixing the ingredients in a different order. I shall try this again soon, and let you know! 🙂 Thanks!!

  5. Dancehocke says:

    I have been dying to try these cupcakes but I would like to know how much buttermilk and oil to? Would you be able to help?

    1. Sure…to a cake mix add buttermilk instead of water {usually 1 cup}, and the amount of oil on the box {usually 1/3 cup}
      Hope that helps!

  6. Darling – where oh where do we find watermelon jello?? Have looked in Bellevue, Seattle, Spokane and Boise. Please help!!

    1. I found the watermelon jello at Walmart. I would think most grocery stores would have it, strange that you can’t find it. Sorry, let me know if I can help.

  7. Hi Liz

    Your cupcakes look fabulous – and how creative, making your own paper wrappers!

    I didn’t make cupcakes this week, but I wanted to share a fabulous cookbook I am giving away with you and your readers. I’m so excited, I’m trying to get the word out to all of my foodie friends!

    Have a fabulous weekend and I will be on the lookout for YOUR great giveaway as well!


  8. Very Cute! Perfect for a picnic & love the wrappers!

  9. I Love how these are pink with “seeds” inside!

  10. These look great! I love how you used the Watermelon Jello for flavoring! Cool liners too!
