Ingredients

Scale
  • 1 ½ cups (190g) all-purpose flour
  • 1 ½ teaspoons baking powder
  • ¾ cup (150g) sugar
  • ¼ teaspoon salt
  • 6 tablespoons (85g) unsalted butter, softened
  • 2 large eggs, room temperature
  • ½ cup (120ml) whole milk, room temperature
  • ¼ cup (60ml) sour cream
  • 1 teaspoon vanilla extract
  • ½ cup (90g) rainbow sprinkles
  • For the frosting:
  • ½ cup (115g) unsalted butter, softened
  • 2 cups (240g) powdered sugar, sifted
  • 1 teaspoon vanilla extract
  • 23 tablespoons (30-45ml) heavy cream
  • Additional sprinkles for decorating

Instructions

  1. Preheat the oven to 350°F (175°C). Line a 12-cup muffin tin with cupcake liners or grease well.
  2. In a large bowl, whisk together the flour, baking powder, sugar, and salt.
  3. In a separate bowl, beat the softened butter until fluffy. Add eggs one at a time, beating well after each addition.
  4. Stir in the milk, sour cream, and vanilla extract into the butter-egg mixture until smooth.
  5. Gradually fold the dry ingredients into the wet mixture using a spatula until just combined.
  6. Carefully fold in the rainbow sprinkles, avoiding overmixing to keep colors bright.
  7. Spoon the batter evenly into the cupcake liners, filling about two-thirds full.
  8. Bake for 18-20 minutes or until a toothpick inserted in the center comes out clean or with a few moist crumbs.
  9. Let cupcakes cool in the pan for 5 minutes, then transfer to a wire rack to cool completely.
  10. To make frosting, beat softened butter until creamy. Gradually add powdered sugar, vanilla extract, and heavy cream, adjusting cream to achieve spreadable consistency.
  11. Frost the cooled cupcakes with a generous swirl and decorate with additional sprinkles.

Notes

Do not overmix the batter to avoid dense cupcakes. Use room temperature ingredients for best texture. Fold sprinkles in gently to prevent color bleeding. Check oven temperature with a thermometer if cupcakes brown too fast or come out dry. Cool cupcakes completely before frosting to prevent melting.
