how to make Lemon Cupcakes with Blueberry Buttercream

Ingredients

  • 1 ½ cups all-purpose flour
  • 1 cup granulated sugar
  • 1 ½ tsp baking powder
  • ¼ tsp salt
  • ½ cup unsalted butter, softened
  • 1 large egg, room temperature
  • ½ cup buttermilk
  • 1 tsp vanilla extract
  • 2 Tbsp fresh lemon juice
  • 1 Tbsp lemon zest
  • 1 cup blueberries (fresh or frozen)
  • 1 cup unsalted butter, softened (for frosting)
  • 3–4 cups powdered sugar, sifted
  • 1 tsp vanilla extract (for frosting)
  • Pinch of salt

Directions

  1. Begin by cooking the blueberries in a small saucepan over medium heat for 8–10 minutes. Mash them as they soften. Strain the mixture through a fine-mesh sieve, return the liquid to the pan, and simmer until it reduces to 2–3 tablespoons. Allow it to cool completely.

  2. Preheat your oven to 350°F (175°C) and line a cupcake pan with liners. In a bowl, whisk together the flour, baking powder, and salt.

  3. In a separate bowl, beat the softened butter and granulated sugar until the mixture is light and fluffy. Add the egg, vanilla extract, lemon juice, and lemon zest, mixing until everything is smooth.

  4. Gradually add the dry ingredients and buttermilk alternately, mixing just until combined. Fill the cupcake liners about two-thirds full with the batter and bake for 18–22 minutes. Once baked, let them cool completely.

  5. For the frosting, beat the softened butter until it is pale and creamy. Gradually mix in the powdered sugar, blueberry reduction, vanilla extract, and a pinch of salt. Whip until the frosting is light and fluffy.

  6. Pipe the blueberry buttercream onto the cooled cupcakes. If you like, you can garnish them with fresh blueberries and a sprinkle of lemon zest for an extra touch.
