Ingredients

Scale
  • 1 ¾ cups all-purpose flour (220g), sifted
  • 1 ½ teaspoons baking powder (6g)
  • ¼ teaspoon salt (1.5g)
  • ½ cup unsalted butter (115g), softened
  • 1 cup granulated sugar (200g)
  • 2 large eggs, room temperature
  • 2 teaspoons pure vanilla extract (10ml)
  • ½ cup whole milk (120ml), room temperature
  • 1 teaspoon fresh lemon zest, finely grated
  • ½ cup rainbow sprinkles (about 80g)
  • For the Buttercream:
  • 1 cup unsalted butter (225g), softened
  • 4 cups powdered sugar (480g), sifted
  • 1 tablespoon pure vanilla extract (15ml)
  • 23 tablespoons heavy cream (30-45ml)
  • A pinch of salt

Instructions

  1. Preheat oven to 350°F (175°C). Line a 12-cup muffin tin with paper liners.
  2. In a medium bowl, whisk together sifted flour, baking powder, and salt. Set aside.
  3. In a large bowl, beat softened butter and granulated sugar with an electric mixer on medium speed for 3-4 minutes until light and fluffy.
  4. Add eggs one at a time, beating well after each addition, then mix in vanilla extract.
  5. Alternately add dry ingredients and whole milk to the butter mixture, starting and ending with dry ingredients. Mix gently after each addition for 2-3 minutes.
  6. Fold in lemon zest and rainbow sprinkles gently using a rubber spatula.
  7. Spoon batter evenly into cupcake liners, filling each about two-thirds full.
  8. Bake for 18-22 minutes until a toothpick inserted in the center comes out clean or with a few moist crumbs.
  9. Cool cupcakes in the pan for 5 minutes, then transfer to a wire rack to cool completely.
  10. For the buttercream, beat softened butter on medium speed for about 2 minutes until creamy.
  11. Gradually add sifted powdered sugar on low speed to avoid sugar clouds, then increase speed and mix for 2-3 minutes.
  12. Add vanilla extract, salt, and heavy cream one tablespoon at a time until smooth and spreadable.
  13. Frost cooled cupcakes using a piping bag with a star tip or a knife, and top with extra sprinkles.

Notes

Use room temperature eggs and butter for best mixing results. Fold sprinkles gently to maintain the firework effect. Sift powdered sugar before making buttercream to avoid graininess. Cool cupcakes completely before frosting to prevent melting. Use non-melting sprinkles for best color retention. For gluten-free, substitute all-purpose flour with gluten-free blend. For dairy-free, replace butter with coconut oil and milk with almond or oat milk.
