How to Make Watermelon Cupcakes
1. Warm up the oven and prep your pan
Kick things off by setting your oven to 350°F (175°C). While it heats, grab your tin and either grease it up or line it with cute cupcake liners. Trust me, this step is your best friend for easy cupcake rescue later.
2. Mix your cupcake batter like a pro
Dump your white cake mix into a big bowl. Add the vegetable oil, egg whites, and a splash of water. Grab your mixer (hand or stand, whatever you’ve got) and blend on medium until your batter is silky smooth, no lumps, no stress.
3. Bring on the watermelon vibes
Here’s the fun part, stir in your watermelon gelatin and vanilla extract. Take your time with the green food coloring, add a few drops, then mix it in until you get that fresh, bright watermelon green that makes you smile.
4. Fill them up, but not too much!
Spoon the mixture into your liners, stopping when they’re around two-thirds full. Give them enough room to puff up without spilling over, because nobody likes a messy oven.
5. Bake and test for perfection
Slide your tray into the oven and let those cupcakes bake for about 18 minutes. When you think they’re done, slide a toothpick into the middle, clean means you’re in the winner’s circle. Let them cool completely, you don’t want frosting sliding off, right?
6. Whip up that dreamy frosting
While your cupcakes chill, it’s time for the frosting party. Beat your softened unsalted butter until it’s fluffy and light, think clouds, but tastier. Then add the vanilla, watermelon gelatin, and a pinch of salt to keep things balanced.
7. Sweeten, soften, and paint it pink
Slowly add your powdered sugar, one cup at a time, folding in a splash of whole milk between each addition. This makes the frosting silky and spreadable, just how it should be. Then add red food coloring until your frosting has that perfect watermelon-pink glow.
8. Frost with flair and enjoy
Pipe or spread your frosting on top, get creative or keep it classic, either way, these cupcakes are pure summer joy in every bite. If you want, sprinkle some mini chocolate chips or just dig in and savor!
Top Mistakes to Skip for Perfect Cupcakes
Overfilling your cupcake liners
It’s tempting to fill those cups to the top, but trust me, fill them about two-thirds full. Too much batter means a volcano eruption in your oven, and nobody wants that messy disaster!
Not letting cupcakes cool completely before frosting
Patience is a virtue, especially here. Let them cool completely so your frosting stays pretty and doesn’t slide off like a tasty snowball.
Adding too much food coloring at once
A little goes a long way! Add your green or red coloring drop by drop and mix well before deciding to add more. You want vibrant colors, not a chemical look.
Mixing batter too long
You want everything blended, but overmixing can make your cupcakes tough instead of tender. Mix just until everything is combined, think of it like a gentle hug for your batter, not a wrestling match.
What to Serve With Your Watermelon Cupcakes
- Iced Mint Lemonade, Fresh, zingy, and a perfect match to cool down your sweet bites.
- Berry Salad, A colorful medley of berries adds a juicy pop and keeps things light.
- Coconut Sorbet, Creamy, tropical, and dreamy, a great contrast to the fruity cupcake.
- Chilled Green Tea, Subtle and refreshing, it won’t overpower those watermelon vibes.
How to Store Your Watermelon Cupcakes
Pop them in the fridge if keeping for longer than 2 days. Because of that yummy watermelon frosting, a cool home helps keep them fresh and tasty.
To freeze cupcakes properly, skip the frosting until you’re ready to serve. Freeze the plain cupcakes wrapped tight, then frost them fresh after thawing. This way, your frosting stays perfect and not icy or weepy.
FAQs
Would using whole eggs instead of egg whites still work?
You sure can! Using whole eggs will make the cupcakes a bit richer and denser, which some folks love. Just keep in mind the texture might be a little less airy compared to using only egg whites, but they’ll still be delicious and moist.
How do I prevent my cupcakes from drying out?
Dry cupcakes are a bummer! To keep them moist, don’t overbake, start checking a couple minutes before the timer’s up. Also, the watermelon gelatin in the batter helps lock in moisture, so don’t skip it.
Why does my frosting sometimes turn out grainy?
Grainy frosting usually happens if your powdered sugar isn’t fully dissolved or if your butter is too cold. To steer clear of this issue, beat the butter until smooth as silk, ease in the sugar, and mix with care, not haste.
