Ingredients

Here's what you'll need:

For the Lemon Cupcakes:

  • 1 ½ cups all-purpose flour
  • 1 ½ teaspoons baking powder
  • ¼ teaspoon salt
  • ¾ cup granulated sugar
  • ½ cup (1 stick) unsalted butter, softened
  • 2 large eggs, at room temperature
  • ½ cup whole milk, at room temperature
  • 2 tablespoons fresh lemon juice
  • 1 tablespoon lemon zest
  • 1 teaspoon vanilla extract

For the Lemon Buttercream Frosting:

  • 1 cup (2 sticks) unsalted butter, softened
  • 3-4 cups powdered sugar, sifted
  • 3 tablespoons fresh lemon juice (or more, to taste)
  • 1 teaspoon lemon zest
  • Pinch of salt
  • 1 teaspoon vanilla extract (optional)

Instructions

  1. Preheat your oven to 350°F (175°C). Line a 12-cup muffin pan with paper liners.
  2. In a medium bowl, whisk together the flour, baking powder, and salt. Set aside.
  3. In a large bowl, cream together the softened butter and granulated sugar with an electric mixer until light and fluffy (about 2-3 minutes).
  4. Beat in the eggs one at a time, mixing well after each addition. Stir in the milk, lemon juice, lemon zest, and vanilla extract until just combined. The mixture might look a little curdled, but don't worry!
  5. Gradually add the dry ingredients to the wet ingredients, mixing on low speed until just combined. Be careful not to overmix the batter.
  6. Divide the batter evenly among the prepared muffin cups, filling each about two-thirds full.
  7. Bake for 18-22 minutes, or until a wooden skewer inserted into the center of a cupcake comes out clean.
  8. Remove the cupcakes from the oven and let them cool in the pan for a few minutes before transferring them to a wire rack to cool completely. They must be entirely cool before frosting.

To make the Lemon Buttercream Frosting:

  1. In a large bowl, beat the softened butter with an electric mixer until creamy and smooth.
  2. Gradually add the sifted powdered sugar, one cup at a time, beating well after each addition until fully incorporated.
  3. Add the lemon juice, lemon zest, pinch of salt, and vanilla extract (if using). Beat on high speed for 3-5 minutes, until the frosting is light, fluffy, and pale in color. If the frosting is too thick, add a tiny bit more lemon juice or milk; if too thin, add more powdered sugar.
  4. Once the cupcakes are completely cool, frost them generously using a piping bag or an offset spatula. Garnish with a little extra lemon zest if desired.

Tips and Variations

  • Do not overmix your cupcake batter! Overmixing develops gluten, leading to tough cupcakes. Mix only until the ingredients are just combined.
  • Ensure all your cold ingredients (butter, eggs, milk) are at room temperature. This helps them emulsify properly, creating a smoother, more uniform batter and a fluffier texture.
  • For an extra punch of lemon, make a simple lemon syrup (equal parts sugar and lemon juice, heated until sugar dissolves) and brush it over the warm cupcakes after they come out of the oven.
  • Try a cream cheese frosting instead of buttercream for a tangier, richer topping.
  • Add a tablespoon of poppy seeds to the cupcake batter for Lemon Poppy Seed Cupcakes!
