If you’re looking for a way to transform boxed cake mix into a cute summer treat, these Watermelon Cupcakes are the perfect recipe for you.
For more ideas of what to make, check out all of our desserts.

I was in Walmart earlier this summer and I saw a box of cupcakes that were decorated to look like watermelons.
Now, if you know me, you know my toxic trait is I’m pretty sure I can re-create anything. That very often turns into Pinterest fails and “Nailed it!” moments, but I had a lot of confidence in my ability to replicate those watermelon cupcakes.
So, I did.
I made them from a boxed cake mix because that makes them a little bit easier.
Of course, if you have a from-scratch white cake mix that you prefer, use it. But, the appeal of these is that they are adorable.
In my experience, when you’re serving someone a cute treat, they eat with their eyes — and never with their taste buds. As long as it’s cute, people will love it and will remember you made it. They absolutely will not remember if you made it from scratch or from the box or how it tasted.
But, of course, as I always say, you do you. Whatever you think is best is best.

Watermelon Cupcakes Ingredients:
You can get the full list of ingredients with measurements in the recipe card below.
- White cake mix – You also need whatever ingredients the cake mix requires.
- Food coloring – You need green food coloring for the cupcakes and red food coloring for the icing.
- Icing – I like the taste of cream cheese icing better than white icing, but as long as it’s white, it’s fine.
- Chocolate chips – We use mini chocolate chips.
How To Make Watermelon Cupcakes:
Quick note before we start: I keep calling these watermelon cupcakes because they look like watermelon, but the flavor isn’t watermelon.
If you wanted to, you could probably add a watermelon extract to the batter or the icing, but I haven’t tried that.

Mix the box ingredients together, according to the directions on the box.
The box I use calls for egg whites, water, and oil. Your recipe may call use other ingredients.
But, you want to use just egg whites not the yolks because you want the cake to be as white as possible so it takes on as much as the green color as possible.
Mix the cake mix with the stand mixer.

Add green food coloring to the cake mix. Stir gently by hand until the green is incorporated.
On the back of the food coloring box, there are recipes to make deeper greens by adding a formula of green, blue, and yellow food coloring.
I’ll be very honest and tell you that I have tried this and it doesn’t matter. Mixing together those three food colorings looks exactly like just adding green food coloring to my untrained eye.
So you can try food coloring math or you could just add green and save yourself a little bit of time.

Add the batter to cupcake molds.
I use a cookie scoop to divvy out the batter so I can make sure that they’re all filled the same and bake evenly.
I also use silicone cupcake liners.
You don’t have to use them, but when you’re serving these, you serve them out of the wrapper so people can see that they look like mini watermelons. If you use silicone molds, the cupcakes easily pop out of the mold. Plus, they’re better for the earth (and your wallet) because they’re reusable.
If you don’t have silicone cupcake molds, you can either use paper cupcake wrappers or grease the muffin tin.

Bake the batter for one minute less than the package says.
This way, the cupcakes don’t get golden brown outside and you’re able to really see the green.
When the cupcakes are done, cool them completely (or at least to room temperature) on a wire cooling rack.
When the cupcakes are cooled, remove them from the silicone baking molds.

Spoon the icing into a small mixing bowl.
Add in the red food coloring.
Use a hand mixer to mix the icing.
You don’t have to use a hand mixer to mix the icing, but I do because store-bought icing has been sitting in the container for a while and it gets flat.
Aerating it by mixing with a hand mixer makes it softer and fluffier. It also expands the icing so you have more without actually purchasing more.

Add the icing to a piping bag with a No. 131 tip.
That tip is my recommendation, but you could use a different sized piping tip.

Pipe the pink frosting (the “watermelon flesh”) on top of the cupcakes.

Sprinkle some mini chocolate chips (the “watermelon seeds”) on top of the icing.
Continue until you’re done with all the cupcakes.

Watermelon Cupcakes: Frequently Asked Questions
You can definitely make these cupcakes ahead of time. Just make sure to keep them in an airtight container in the fridge so that the icing doesn’t start to melt.
I dropped some off to a friend who left them on her porch for five hours and the icing was still fine then, but I do recommend storing them in a cool area for the best results.
If you store leftover cupcakes in an airtight container in the fridge, they’ll be freshest if you eat them within a week.
I often say you can pipe using a zip top plastic bag if you don’t have a piping bag. I used to do that all the time.
But that doesn’t really work with cupcakes. You get a really uneven icing.
In general, you could use an icing knife, but that would leave the icing so flat and you really benefit from the height of the icing here.

These are so cute! I agree with you on the box mix, and cream cheese frosting is DEFINITELY better than vanilla. :)
