Description
These homemade lemon cupcakes are soft, buttery, and packed with fresh lemon flavor, especially when filled with lemon curd! Made with fresh lemon zest and juice, the bright citrus taste is balanced by a sweet, creamy vanilla buttercream on top. If you’re looking for an easy lemon cupcake recipe that’s moist, tender, and reliable, your search ends here.
Ingredients
Lemon Cupcakes
- 1 and 1/2 cups (188g) all-purpose flour (spooned & leveled)
- 2 teaspoons baking powder
- 1/2 teaspoon salt
- 1/2 cup (8 Tbsp; 113g) unsalted butter, softened to room temperature
- 1 cup (200g) granulated sugar
- 1 Tablespoon lemon zest
- 2 large eggs, at room temperature
- 1 and 1/2 teaspoons pure vanilla extract or vanilla bean paste
- 1/2 cup (120ml) whole milk or buttermilk, at room temperature
- 1/4 cup (60ml) fresh lemon juice
- optional filling: homemade lemon curd, cooled completely
Vanilla Buttercream Frosting
- 1 cup (16 Tbsp; 226g) unsalted butter, softened to room temperature
- 4 cups (480g) confectioners’ sugar, plus more as needed
- 1/4 cup (60ml) heavy cream, half-and-half, or whole milk, at room temperature
- 2 teaspoons pure vanilla extract or vanilla bean paste
- salt, to taste
- optional for garnish: lemon slices and/or mint sprigs
Instructions
- Preheat the oven to 350°F (177°C). Line a 12-cup muffin pan with cupcake liners.
- Make the batter: Whisk the flour, baking powder, and salt together in a large bowl. Set aside.
- Using a handheld or stand mixer fitted with a paddle attachment, beat the butter, sugar, and lemon zest together on medium-high speed in a large bowl until creamed, about 3 minutes. Scrape down the sides and bottom of the bowl as needed. (Here’s a helpful tutorial if you need guidance on how to cream butter and sugar.) Add eggs and vanilla, and then beat on medium-high speed until combined, about 1 minute. Scrape down the sides and bottom of the bowl as needed.
- Add the dry ingredients and then turn the mixer on low speed and slowly pour in the milk and lemon juice. Beat until just combined. Do not overmix.
- Pour/spoon the batter evenly into the liners. Bake for 18–21 minutes, or until a toothpick inserted in the center comes out clean. Allow the cupcakes to cool completely before filling and frosting.
- Fill the cupcakes (optional): Using a sharp knife, cut a circle into the center of the cooled cupcakes to create a little pocket about 1 inch deep. The piece you removed will be sort of cone-shaped. Spoon cooled, thickened lemon curd inside each carved-out cupcake—use however much will fit. (I use a teaspoon measuring spoon for this. Usually you can fit between 1–2 teaspoons of filling in each.) Slice/tear off the pointy end of the “cone” piece of cupcake you removed, and gently press the round piece back on top of the filling. See my How to Fill Cupcakes post if you need extra visuals or help with this step, or if you want to pipe the curd in with a piping tip.
- Make the frosting: With a handheld or stand mixer fitted with a paddle attachment, beat the butter on medium speed until creamy, about 2 minutes. Add the confectioners’ sugar, heavy cream/milk, and vanilla. Beat on low speed for 30 seconds, then increase to medium-high speed and beat for 2 full minutes. Taste. Add a pinch of salt if frosting is too sweet. I always add 1/8 teaspoon. Add up to 1/2 cup more confectioners’ sugar if frosting is too thin, or more cream/milk—a Tablespoon at a time—if frosting is too thick.
- Frost cooled cupcakes and top each with a lemon slice and/or mint sprig, if desired. You can swipe the frosting on with an icing knife or use a piping tip such as Wilton 1M or Ateco 826.
- Store leftover cupcakes in the refrigerator for up to 4 days. A cupcake carrier makes storing and transporting easy.
Notes
- Make Ahead & Freezing Instructions: Make and fill the cupcakes 1 day in advance. Keep the cupcakes covered tightly at room temperature or in the refrigerator. Frost the next day. Unfrosted cupcakes can be frozen up to 2 months. Thaw overnight in the refrigerator and bring to room temperature before frosting and serving.

- Lemons: You need about 2–3 medium lemons to yield this amount of zest and juice.
- Whole Milk or Buttermilk: You can use either. You can use lower-fat or nondairy milks in a pinch, but the cupcakes won’t taste nearly as rich and moist.
- Lemon Curd Filling: This is optional, and I recommend using homemade lemon curd. Make sure it’s prepped in advanced and has thickened and cooled completely.
- Mini Cupcakes: For around 30–36 mini cupcakes, bake for about 11–13 minutes, same oven temperature. I do not recommend filling mini cupcakes; they’re simply too small.
