A recipe for perfect vanilla cupcakes stuffed with lemon curd and topped with lemon buttercream. Your new favorite dessert and heaven in every bite!
More lemons today for you, my dears! This recipe features the lightest and most perfect vanilla cupcake recipe I’ve ever tasted. Seriously. And they are so easy to make! No ‘room temperature eggs’ or fancy ingredients. They are my new favorite thing and I’m going to make them again and again.
This tasty morsel of a cupcake is stuffed with silky lemon curd and topped with a light and slightly tart lemon buttercream. The combination of the three components is absolute perfection.
If you’re wondering how I put lemon curd into cupcakes, it’s so easy! Just use an apple corer to gently twist out the center of the cupcake. Then add the filling of your choice and add frosting. This also works if you want to stuff the cupcakes with buttercream frosting.
To frost the white cupcakes, I used an extra large closed star tip to pipe a single ring around each cupcake. If you want more lemon, you could even spoon a bit of extra curd in the center. Or spoon an extra bit into your mouth, ifyouknowwhatimean.

Vanilla Cupcakes Stuffed with Lemon Curd
A recipe for perfect vanilla cupcakes stuffed with lemon curd and topped with lemon buttercream. Heaven in every bite!
- Prep Time: 1 hour 30 minutes
- Cook Time: 20 minutes
- Total Time: 1 hour 50 minutes
- Yield: 14 cupcakes
- Category: Dessert
- Method: Oven
- Cuisine: American
For the vanilla cupcakes:
- 1 1/2 cup (150 grams) cake flour
- 1 1/2 teaspoons baking powder
- 1/4 teaspoon salt
- 1/2 cup unsalted butter (1 stick) at room temp
- 1 cup sugar
- 2 eggs
- 1/2 teaspoon vanilla
- 1/2 cup milk
For the lemon curd (makes extra):
- 1/3 cup lemon juice, about 2 lemons
- 2 large eggs
- 1 egg yolk
- 1/2 cup sugar
- 2 tablespoons chilled unsalted butter, cut into 1/2-inch cubes
- 1 tablespoon heavy cream
- 1/4 teaspoon vanilla extract
- pinch table salt
For the Meyer lemon buttercream:
- 1/2 cup egg whites (about 3 large eggs)
- 1 cup granulated sugar
- 1 cup (2 sticks) unsalted butter, cut into 1 inch pieces
- 1 tablespoon finely grated lemon zest
- 1 tablespoon fresh lemon juice
Make the vanilla cupcakes:
- Combine the dry ingredients. Beat in the butter on medium low. The mixture should resemble coarse sand. Beat in the sugar on low.
- Add the eggs one at a time, then the vanilla and milk. Mix until just combined.
- Using an ice cream scoop or a spoon, pour into lined cupcake pan until 2/3 full.
- Bake at 350 for 20 minutes or until a toothpick comes out clean. Let cool completely before frosting.
Make the lemon curd filling:
- Heat lemon juice over medium heat until hot but not boiling.
- Meanwhile, whisk eggs and yolk in a medium bowl. Gradually whisk in the sugar. While whisking, slowly pour hot lemon juice into the eggs. Return to saucepan and cook over medium heat. Stir constantly with a wooden spoon until mixture registers 170 degrees and coats the back of a spoon.
- Remove pan from heat and stir in butter. Once melted, stir in cream, vanilla, and salt.
- For a more even texture, strain mixture through a fine-mesh strainer (optional). Curd is able to be stored in an airtight container in the fridge for up to two weeks, just cover with plastic wrap to prevent it from drying out.
Make the lemon buttercream:
- Bring a medium pot filled with one inch of simmering water to a boil. Place the egg whites and sugar in a stainless-steel bowl (like a stand mixer bowl) and place on saucepan. Use a whisk to beat the mixture until very hot (about 160F).
- Remove from heat and mix with the whisk attachment on high until it is cool, thick and glossy and has tripled in volume, about 5 minutes.
- Reduce speed to medium and add butter a few pieces at a time. Add the lemon zest and lemon juice and continue to beat until smooth and fluffy.*
Assemble the cupcakes:
- Use an apple corer to gently hollow out the center of each cupcake, not going through the whole depth of the cupcake.
- Spoon lemon curd into each cupcake. I like using an espresso spoon for this part!
- Use an extra large closed star frosting tip to pipe a rosette on each cupcake. If you want, you can leave a space in the center and fill it with more lemon curd. Finish with a sprinkle of coarse sugar.
Notes on Making & Troubleshooting Buttercream Frosting: If the frosting is too soft and doesn’t seem to be coming together, it’s possible that it’s too warm. You could try popping it into the fridge for 10-15 minutes and then re-mixing with the paddle attachment in your electric mixer until it comes together and is smooth and satiny. In general it’s hard to over-whip buttercream, so I would err on the side of mixing it longer to see if you can salvage it, even as long as 15 minutes!
