One summer afternoon, my daughter and I spent the whole day planning a little backyard picnic to surprise her dad after a rough week at work. We made sandwiches, cut up fruit, and then she begged to bake something “pretty and pink.” That’s how we landed on these Strawberry Lemonade Cupcakes.
We wanted something light, a bit tart, and sweet enough to feel like a treat—something that tastes like sunshine in cupcake form. She mashed the strawberries while I zested the lemons, and our kitchen smelled like pure happiness.
I’ve made these cupcakes a few more times since then—once for a school bake sale, once for my neighbor’s birthday, and once just because we needed cheering up on a rainy day. They’re easy to whip up and always a hit, even with people who “don’t like fruity desserts” (their words, not mine).
The combination of fresh lemon and strawberries hits that perfect balance—bright, refreshing, and not too sweet. And the buttercream? That creamy topping with little flecks of real strawberry makes all the difference.
Short Description
Light, fluffy strawberry cupcakes are filled with tart lemon curd and topped with dreamy lemonade buttercream in pink and yellow swirls—perfectly fresh, fun, and summery.

Cooking Instructions
Step 1: Prep the Oven and Pan
Preheat oven to 350°F (175°C). Line a 12-cup muffin tin with liners.
Step 2: Make the Cupcake Batter
In a large bowl, combine cake mix, water, oil, and eggs. Beat on medium for 2 minutes until smooth and evenly colored.
Step 3: Bake the Cupcakes
Fill liners about ¾ full. Bake 18–22 minutes or until a toothpick comes out clean or with moist crumbs. Cool completely before filling.
Step 4: Fill with Lemon Curd
Use a cupcake corer or small knife to remove a bit of the center. Add 1–2 teaspoons lemon curd into each cupcake. Replace the tops if desired.
Step 5: Make the Lemonade Buttercream
Beat butter until fluffy. Gradually add powdered sugar, then lemon juice and zest. Mix until smooth and creamy.
Step 6: Add Color
Divide frosting into two bowls. Tint one pink, the other yellow using gel colors.
Step 7: Pipe the Swirl
Spoon both frostings side-by-side into a piping bag. Pipe tall swirls on cupcakes. Garnish with sprinkles, zest, or mini lemon slices.

FAQs
1. Can I make cupcakes from scratch instead of mix?
Certainly! Use a basic strawberry cupcake recipe, but flavors and texture will vary slightly.
2. Is lemon curd necessary?
It adds a zesty surprise. You can skip it, but curd really brightens the flavor.
3. Can I pipe just one color?
Of course, pink or yellow alone still look and taste delightful.
4. What if my frosting is too soft?
Chill it for 10 minutes or add ¼ cup more powdered sugar.
5. Can I use bottled lemon juice?
Yes, but fresh gives a brighter flavor and natural zest aroma.
Tips & Tricks
Let cupcakes cool completely before filling or frosting to avoid melting.
Use room-temperature butter for smoother frosting.
Try adding a drop of vanilla bean paste for extra depth.
Garnish with edible flowers for a fancy finish.
To soften curd’s sweetness, mix in a teaspoon of Greek yogurt before filling.
