Lemon Meringue Cupcakes Curd

The first time I made these, my kitchen smelled like a sunny lemon grove and I accidentally set off the smoke detector while torching the meringue. My roommate came running in, ready to call the fire department, only to find me dramatically blowtorching cupcakes with tears in my eyes from laughing so hard. Now it is our little tradition to make these whenever we need something impossibly cheerful and slightly dramatic. The combination of tangy curd and pillowy meringue somehow feels like eating a cloud that spent its vacation in citrus country.

I brought these to a spring potluck last year and watched my friend's grandmother close her eyes after the first bite, memories apparently flooding back of her own lemon meringue pies from decades past. She asked for the recipe three separate times throughout the afternoon. There is something about this particular combination of flavors that makes people want to share their own kitchen stories while eating them.

Ingredients

• 1 1/4 cups all-purpose flour: The foundation that holds everything together—measure by spooning into your measuring cup and leveling off for accuracy
• 1 teaspoon baking powder: Gives these cupcakes their tender rise without making them taste metallic or overly dense
• 1/4 teaspoon baking soda: Works with the acidic lemon juice to create extra lift and a golden crumb
• 1/4 teaspoon salt: Enhances all the other flavors and keeps the cupcakes from tasting flat or overly sweet
• 1/2 cup unsalted butter, softened: Room temperature butter creates a perfectly tender crumb—leave it out for at least an hour before baking
• 3/4 cup granulated sugar: Sweetens the cake while still letting the bright lemon shine through
• 2 large eggs, room temperature: Room temperature eggs emulsify better into the batter for a uniform texture
• 2 teaspoons lemon zest: The essential oils in the zest pack way more punch than juice alone—zest directly into the sugar to release those oils
• 2 tablespoons fresh lemon juice: Adds tang and reacts with the baking soda for extra lift
• 1/2 teaspoon pure vanilla extract: Rounds out the sharp citrus notes with warm undertones
• 1/2 cup whole milk: Creates tenderness and moisture—whole milk really does make a difference here
• 2 large egg yolks: The foundation of your silky curd—their rich proteins create that luxurious texture
• 1/3 cup granulated sugar: Sweetens the curd just enough to balance the intense lemon acidity
• 2 tablespoons unsalted butter: Adds richness and helps the curd set up beautifully in the refrigerator
• 1 tablespoon finely grated lemon zest: Intensifies the lemon flavor and adds those beautiful golden specks throughout the curd
• 1/4 cup fresh lemon juice: The star of the show—fresh juice makes all the difference over bottled
• Pinch of salt: Wakes up all the flavors and keeps the curd from tasting one dimensional
• 2 large egg whites: Whip up into those gorgeous cloud like peaks that crown each cupcake
• 1/2 cup granulated sugar: Stabilizes the meringue and adds just the right amount of sweetness
• 1/4 teaspoon cream of tartar: The secret to stable meringue that holds its shape even after toasting
• 1/2 teaspoon vanilla extract: Adds depth to the meringue so it tastes like more than just sweetened egg whites

Instructions

Getting Started:

Preheat your oven to 350°F and line a 12 cup muffin tin with paper liners. This step seems basic but lining the pan before you start mixing prevents that frantic scrambling when your batter is ready.

Whisking the Dry Ingredients:

In a medium bowl, whisk together flour, baking powder, baking soda, and salt until thoroughly combined. Set this aside while you work on the wet ingredients.

Creaming Butter and Sugar:

Beat the softened butter and sugar in a large bowl until the mixture looks pale and fluffy, about 3 minutes. This creates air pockets that make the cupcakes tender.

Adding Eggs and Flavor:

Add eggs one at a time, beating well after each addition. Mix in lemon zest, lemon juice, and vanilla extract until everything is incorporated.

Combining Wet and Dry:

Add the flour mixture in three parts, alternating with milk in two parts, starting and ending with the flour. Mix gently until just combined—over mixing makes tough cupcakes.

Baking the Cupcakes:

Divide batter evenly among the liners, filling each about two thirds full. Bake for 18 to 20 minutes until a toothpick comes out clean. Cool in the pan for 5 minutes before transferring to a wire rack.

Making the Lemon Curd:

Whisk together egg yolks, sugar, lemon zest, lemon juice, and salt in a small saucepan. Cook over medium heat, stirring constantly until thickened enough to coat a spoon, about 5 to 7 minutes.

Finishing the Curd:

Remove from heat and stir in butter until completely melted and smooth. Press plastic wrap directly onto the surface and refrigerate until completely set, at least 2 hours.

Preparing the Meringue:

In a clean, grease free bowl, beat egg whites and cream of tartar until foamy. Gradually add sugar one tablespoon at a time, beating until stiff glossy peaks form. Fold in vanilla.

Filling the Cupcakes:

Use a small knife or cupcake corer to remove a cone from the center of each cooled cupcake. Fill each cavity with a generous teaspoon of chilled lemon curd.

Adding the Meringue:

Pipe or spoon meringue over each cupcake, creating swirls and peaks that will toast beautifully. Use a kitchen torch to golden the meringue, or broil for 1 to 2 minutes watching constantly.

My sister requested these for her birthday instead of a traditional cake, and watching her face light up when she bit into that first curd filled cupcake reminded me why baking for people we love matters so much. She said it was like getting a hug from someone who just came in from a lemon orchard.

Getting That Perfect Meringue Texture

The difference between a meringue that holds its shape and one that weeps into a sad puddle comes down to patience and room temperature egg whites. I learned this the hard way after several batches of meringue that looked gorgeous going into the oven but collapsed into sticky sweetness within minutes. Take your time adding the sugar—literally one tablespoon at a time while the mixer runs on medium high speed. Each addition needs time to dissolve completely before the next goes in, and you should be able to rub a bit between your fingers and feel no grit. The cream of tartar is not optional here either—it is the insurance policy that keeps everything stable when you apply that torch.

Filling Without the Mess

Early attempts at filled cupcakes ended with curd everywhere except inside the cake where it belonged. I finally figured out that cutting a small cone shape out of the center, trimming the point off that cone, then placing the cap back on top like a little hat works infinitely better than trying to pipe filling blindly into the cupcake. The curd stays contained, and when someone bites in they get that perfect surprise moment of tangy filling. For the cleanest holes, use a small round cutter or the back of a piping tip—twist gently and pull straight up. Fill each cavity with about one teaspoon of curd, less if you plan to pile on generous meringue.

Making These Ahead

You can bake the cupcakes up to two days ahead and store them in an airtight container at room temperature. The lemon curd keeps for a week in the refrigerator, actually developing deeper flavor after a day or two. However, once assembled, these need to be eaten within 24 hours or the meringue starts to weep and the cupcakes get soggy. If you are serving these for a special occasion, bake and fill the cupcakes the day before, then make and apply the meringue right before serving. The torching step takes literally minutes but creates that wow factor that makes people think you spent all day in the kitchen.

• Unfilled cupcakes freeze beautifully for up to three months—thaw overnight before filling
• If your kitchen is particularly humid, add an extra pinch of cream of tartar to help stabilize the meringue
• A piping bag with a large star tip creates the most dramatic and professional looking meringue swirls

Every time I pull a tray of these from the oven, I am reminded that the most impressive desserts often come from the simplest ingredients treated with care and patience. Hope these bring as much sunshine to your kitchen as they have to mine.

Use a kitchen torch to carefully toast the meringue until golden brown or place under a broiler briefly while watching closely to avoid burning.

→ How to prevent cupcakes from becoming soggy with the curd filling?

Allow cupcakes to cool completely before filling and avoid overfilling to maintain texture. Refrigerate leftovers to preserve freshness.

Yes, lemon curd can be made in advance and chilled. Cover with plastic wrap pressed onto the surface to prevent a skin from forming.

→ What texture should the meringue have when ready to pipe?
