For the Cupcakes:

  • 1 1/4 cup all-purpose flour
  • 1 cup sugar
  • 2 teaspoons lemon zest
  • 1 1/2 teaspoons baking powder
  • 1/4 teaspoon salt
  • 1 large egg
  • 1/3 cup milk
  • 1/4 cup vegetable oil
  • 2 tablespoons lemon juice
  • 1/2 teaspoon lemon extract
  • 1/2 cup boiling water

For the Frosting:

  • 1/2 cup unsalted butter room temperature
  • 1 3/4 cup powdered sugar
  • 1 teaspoon heavy whipping cream
  • 1/2 teaspoon lemon extract
  • pinch of salt
  • lemon zest for garnish
  • lemon slices for garnish


For the Cupcakes:

  • Preheat oven to 350 degrees F. Line a muffin tin with paper liners.
  • In a mixing bowl, whisk together the flour, sugar, zest, baking powder, and salt. Push mixture to the outside of the bowl, creating a well.
  • Add the egg, milk, vegetable oil, lemon juice, and extract. Mix until everything is combined. Add the boiling water and whisk until smooth.
  • Pour batter into paper liners (I like to use a 1/4 measuring cup or large trigger ice cream scoop). Bake for 15-18 minutes until toothpick come out clean. Remove cupcakes from tin and allow to cool on a wire rack . Frost when cool.

For the Frosting:

  • In the bowl of a stand mixer (with paddle attachment), beat the butter for 2 minutes on medium-high until light and fluffy. 
  • Set the mixer to low speed and slowly add in the powdered sugar followed by the cream, extract, and salt. Increase speed to medium and beat for about 5 minutes or pale in color. 
  • Frost cupcakes, sprinkle with zest, and top with half a lemon slice.
