For the Cupcakes:

  • 1 box lemon cake mix and ingredients to make
  • zest of 1 lemon
  • 1 teaspoon Adam's Lemon Extract
  • ¾ cup lemon curd store-bought or homemade

For the Frosting:

  • 3 sticks unsalted butter at room temperature
  • 5-6 cups powdered sugar
  • 2 ½ tablespoon strawberry gelatin powder
  • 1 teaspoon salt
  • 2 tablespoon milk or cream


  • Preheat the oven to 350 degrees. Line two cupcake pans with paper liners.
  • Add the cake mix and ingredients from the box to a stand mixer.
  • Mix on medium speed until combined.
  • Add in lemon zest and extract and mix until combined.
  • Divide batter into paper liners, filling each about ⅔ of the way full.
  • Bake according to box directions, usually 18-20 minutes.
  • Transfer cupcakes to wire racks to cool completely.
  • Use a paring knife to cut a small cone shape out of the top of each cupcake. Fill with a dollop of lemon curd. Place the removed cake piece back on top.
  • Prepare the frosting by adding the butter to the bowl of a stand mixer. Beat on medium high speed for 3-4 minutes.
  • Add in powdered sugar 1 cup at a time.
  • Add in the strawberry gelatin powder, salt and milk.
  • Transfer frosting to a piping bag and pipe frosting on top of cupcakes.
  • Garnish with sprinkles, fresh strawberries or lemon slices.


If you can't find lemon cake mix, use white or vanilla cake mix and increase the lemon extract to 1 tablespoon.
