What Makes These Cupcakes Special
These aren’t your average lemon cupcakes. The base is made with sour cream, which keeps the crumb incredibly moist and tender while adding a subtle richness that balances the brightness of the lemon. A hollow carved into the center of each baked cupcake is filled with lemon curd — either homemade or store-bought — for a jammy, citrusy surprise that you hit right in the middle of every bite.
The frosting is a Swiss meringue, which means the egg whites and sugar are gently heated together before whipping. This creates a frosting that is silkier, more stable, and less sweet than a basic buttercream. Finished with a kitchen torch to lightly char the peaks, these cupcakes look like they came straight from a bakery window.

Ingredients
For the Lemon Cupcakes:
- ¼ cup unsalted butter, softened
- ½ cup granulated sugar
- 1 large egg
- Zest of 1 lemon
- 2 tablespoons freshly squeezed lemon juice
- ½ teaspoon vanilla extract
- ¼ teaspoon salt
- 1½ teaspoons baking powder
- 1 cup all-purpose flour
- 6 tablespoons sour cream
For the Filling:
- 1 batch lemon curd (homemade or store-bought)
For the Swiss Meringue Frosting:
- ½ cup granulated sugar
- 2 egg whites, room temperature
- ¼ teaspoon cream of tartar
- ½ teaspoon vanilla extract
Ingredient Notes
Butter — Make sure it’s fully softened to room temperature before creaming. Cold butter won’t incorporate properly and will result in a dense cupcake.
Sour cream — This is the key to an ultra-moist crumb. Don’t substitute with milk or yogurt if you can avoid it — the fat content in sour cream makes a real difference.
Fresh lemon juice and zest — Please use fresh lemons here, not bottled lemon juice. The zest carries the most intense lemon flavor and makes these cupcakes taste vibrant and aromatic.
Lemon curd — You can use a good-quality store-bought lemon curd or make your own. Either way, it should be well chilled before filling the cupcakes so it holds its shape.
Egg whites — For the best meringue, use egg whites that are at room temperature. Cold egg whites take much longer to whip and may not reach stiff peaks as easily.
Cream of tartar — This stabilizes the meringue and helps it hold its structure. Don’t skip it.
Step-by-Step Instructions
Step 1: Prep your pan and preheat.
Preheat your oven to 350°F. Line a standard cupcake pan with 8 paper liners and set aside.
Step 2: Mix the dry ingredients.
In a small bowl, whisk together the flour, baking powder, and salt. Set aside.
Step 3: Make the cupcake batter.
In a large bowl or the bowl of a stand mixer, cream together the softened butter and granulated sugar on medium speed until the mixture is light, pale, and fluffy — about 2 to 3 minutes. Add in the egg, lemon zest, lemon juice, and vanilla extract, and mix until smooth and well combined. Scrape down the sides of the bowl as needed. With the mixer on low, alternate adding spoonfuls of the flour mixture and the sour cream, beginning and ending with flour. Mix just until the batter is smooth and no flour streaks remain.
Step 4: Bake the cupcakes.
Divide the batter evenly among the 8 prepared liners, filling each about two-thirds full. A large cookie scoop makes this easy and keeps portions consistent. Bake for 18 to 20 minutes, or until a toothpick inserted into the center comes out with only a few moist crumbs. Let the cupcakes cool completely on a wire rack before filling.
Step 5: Fill with lemon curd.
Using a sharp paring knife or a cupcake corer, carefully cut out the center of each cooled cupcake, making sure to leave the bottom intact. Fill each cavity generously with lemon curd using a small spoon or a pastry bag. Place the filled cupcakes in the refrigerator to chill while you prepare the meringue frosting.
Step 6: Make the Swiss meringue frosting.
Set a heatproof bowl over a saucepan of gently simmering water, making sure the bottom of the bowl doesn’t touch the water. Add the egg whites, granulated sugar, and cream of tartar to the bowl. Whisk constantly until the mixture is warm to the touch, the sugar is completely dissolved, and the mixture is frothy — about 3 to 5 minutes. Remove from heat and immediately beat with a hand mixer or stand mixer fitted with the whisk attachment on high speed until the meringue is glossy and stiff peaks form. Add the vanilla extract during the last 30 seconds of mixing.
Step 7: Pipe and torch.
Transfer the meringue to a large piping bag fitted with your desired tip. Pipe generously onto the chilled cupcakes. Using a kitchen torch, lightly char the tops of the meringue just until golden peaks appear and a few spots are delicately browned. Serve immediately or store chilled until ready to serve.
Expert Tips
- Cool cupcakes completely before filling. If the cupcakes are even slightly warm, the lemon curd will melt and become runny inside.
- Chill before frosting. Chilling the filled cupcakes firms up the curd and creates a stable base for the meringue.
- Make the meringue just before serving. Swiss meringue is best piped and torched fresh. It can weep and deflate if left too long in a warm environment.
- Use a clean, grease-free bowl for the meringue. Any trace of fat will prevent the egg whites from whipping properly. Wipe your bowl and whisk with a little lemon juice or white vinegar before starting.
- Don’t over-torch. Move the flame in slow, even circles at about 4 to 6 inches from the surface. A light golden char is the goal — not a fully browned meringue.
Variations
Double lemon — Stir 2 tablespoons of lemon curd directly into the cupcake batter for an even deeper lemon flavor throughout.
Raspberry lemon — Add a small spoonful of raspberry jam on top of the lemon curd filling before frosting for a gorgeous fruity twist.
Lime meringue cupcakes — Swap the lemon juice and zest for lime and use lime curd for the filling for a tropical variation.
Honey meringue — Replace ¼ cup of the granulated sugar in the meringue with honey for a warmer, floral sweetness.
Mini cupcakes — Use a mini muffin pan and reduce the bake time to 10 to 12 minutes for bite-sized party-ready treats.
Storage and Make-Ahead Tips
Cupcakes (unfrosted): Baked and filled cupcakes can be stored in an airtight container in the refrigerator for up to 3 days.
Meringue frosting: Swiss meringue is best made fresh and used the same day. It does not freeze or store well once piped.
Make ahead: You can bake and fill the cupcakes a day in advance, then prepare and pipe the meringue just before serving for the best results.
Avoid storing at room temperature: Because of the egg-white meringue and lemon curd filling, these cupcakes should always be kept refrigerated.

FAQ
Can I use store-bought lemon curd?
Absolutely. A high-quality jarred lemon curd works perfectly here and saves time. Just make sure it’s well chilled before using.
Do I need a kitchen torch?
The torch is what gives the meringue that classic toasted finish, but if you don’t have one, you can place the frosted cupcakes under a broiler for 1 to 2 minutes — watch them very closely.
Can I make these cupcakes gluten-free?
Yes, you can substitute the all-purpose flour with a 1:1 gluten-free baking flour blend. The texture may be slightly different but the flavor will still be wonderful.
Why did my meringue weep or deflate?
This usually happens if the sugar wasn’t fully dissolved during the double-boiler step, or if there was any grease in the bowl. Make sure to heat the mixture long enough and use a completely clean bowl and whisk.
Can I freeze these cupcakes?
You can freeze the plain baked cupcakes (before filling and frosting) for up to 1 month. Thaw overnight in the fridge, then fill and frost before serving.
