Lemon Buttermilk Cupcakes



for the lemon vanilla cupcakes

  • 1/2 cup (1 stick) unsalted butter, melted
  • 12/3 cups all-purpose flour
  • 1/2 tsp baking powder
  • 1/4 tsp baking soda
  • 1/2 tsp kosher salt
  • 2 egg whites
  • 1 cup organic cane sugar
  • zest of one lemon
  • 3/4 cup buttermilk, room temperature
  • 1/4 cup sour cream,¹ room temperature
  • 3 tsp pure vanilla extract

for the cream cheese frosting

  • 8 oz cream cheese, softened
  • 1/2 cup (1 stick) unsalted butter, softened
  • 1/2 tsp pure vanilla extract
  • 3 cups confectioners (powdered) sugar, sifted
  • 23 tsp milk or cream, as needed
  • fresh berries, for garnish


for the lemon buttermilk cupcakes

  1. Preheat the oven to 350℉. Line a 12-cup muffin tin with paper liners. Set aside.
  2. Melt the butter in the microwave or in a small sauté pan. Set aside to cool slightly.
  3. In a medium mixing bowl, sift together the flour, baking powder, baking soda, and salt. Set aside.
  4. In a stand up mixer fitted with the paddle attachment, whisk the egg whites on high speed until stiff peaks form.
  5. Meanwhile, in a large mixing bowl, whisk together the melted butter, sugar, and lemon zest until combined. Stir in the buttermilk, sour cream, and vanilla until smooth and creamy.
  6. Add the flour mixture to the wet ingredients and stir until just combined, being careful not to over-mix. Gently fold in the egg whites.
  7. Use a cookie scoop to divide the batter between the prepared muffin tins, filling each just about all the way to the top.
  8. Bake for 18-22 minutes, until the tops are barely golden and a cake tester inserted into the center of each cupcake comes out clean. Remove from the oven and let cool in the muffin tin for 5 minutes, before transferring to a wire baking rack to cool. Be sure the cupcakes have completely cooled to room-temperature before frosting.

for the cream cheese frosting

  1. In a standup mixer fitted with the paddle attachment, or with a hand-held mixer, mix together the softened cream cheese and butter on medium-high speed until soft and fluffy, about 2 minutes. Stir in the vanilla.
  2. Add the sifted powdered sugar, and continue mixing until completely combined, and no lumps remain. Add milk or more powdered sugar as needed to reach a thick, spreadable consistency.
  3. When the cupcakes have completely cooled, use a piping bag (I used a simple #1 tip here) to pipe on the frosting. Alternatively, use a knife to spread on the frosting. Top with fresh berries or sprinkles, as desired. Enjoy!!


¹ Sour cream made from whole milk (not low fat or fat free) is best for these cupcakes.
