How to Make Strawberry Lemonade Cupcakes

1. Bake the Cupcakes

Preheat your oven to 350°F (175°C) and line a muffin tin with 12 cupcake liners.

In a large bowl, combine the cake mix, water, oil, and eggs. Mix for about 2 minutes on medium speed until smooth.

Divide the batter evenly between the liners, filling each about ¾ full. Bake for 18–22 minutes or until a toothpick comes out clean. Let the cupcakes cool completely before filling.

2. Fill with Lemon Curd

Once cooled, use a cupcake corer or a small knife to cut out a center from each cupcake (about the size of a marble). Fill each cavity with 1–2 teaspoons of lemon curd. You can gently press the removed cupcake top back in, or leave it open—it’s up to you!

3. Make the Lemonade Buttercream

In a large mixing bowl, beat the softened butter until it’s light and fluffy.

Gradually add the powdered sugar, followed by lemon juice and lemon zest. Beat until the frosting is smooth, creamy, and holds its shape.

Divide the frosting into two bowls. Tint one half pink and the other yellow using gel food coloring for vibrant results.

4. Swirl and Decorate

Scoop the pink and yellow frostings side by side into a piping bag fitted with your favorite tip (a large star tip works beautifully!).

Pipe tall swirls onto each cupcake. Decorate with sprinkles, a tiny lemon slice, or a dusting of zest if you’re feeling fancy.

What to Serve with Strawberry Lemonade Cupcakes

These cupcakes pair beautifully with:

Iced tea or lemonade
A scoop of vanilla ice cream
Fresh strawberries or fruit salad
Sparkling rosé for a grown-up twist!

Tips for Perfect Cupcakes

Don’t overmix the batter – mix until just combined for a tender crumb.
Cool completely before filling or frosting to prevent melting.
Use gel food coloring – it gives bright color without thinning the buttercream.
Practice piping on parchment before decorating your cupcakes if you’re new to it!

Storage Instructions

Room temperature: Store unfrosted cupcakes in an airtight container for up to 2 days.

Fridge: Frosted cupcakes with curd can be kept refrigerated for up to 4 days. Bring to room temperature before serving.

Freezer: You can freeze unfrosted cupcakes for up to 3 months. Thaw overnight in the fridge, then frost and fill.

Frequently Asked Questions

Can I use homemade lemon curd?

Absolutely! Homemade lemon curd is rich, fresh, and takes these cupcakes to the next level.

Can I make these gluten-free?

Yes—just use a gluten-free strawberry cake mix and double-check all other ingredients.

What piping tip should I use for the swirl?

I recommend a large open star tip like Wilton 1M or 2D for big, beautiful swirls.

How can I get vibrant color without using too much dye?

Use gel food coloring—it’s super concentrated and won’t affect the buttercream’s texture.
