Ingredients

Scale
  • 1 ½ cups all-purpose flour (190 g), sifted
  • 1 ½ teaspoons baking powder
  • ¼ teaspoon salt
  • ½ cup (1 stick) unsalted butter, softened
  • ¾ cup granulated sugar
  • 2 large eggs, room temperature
  • 2 teaspoons pure vanilla extract
  • ½ cup whole milk, room temperature
  • 1 cup (2 sticks) unsalted butter, softened (for frosting)
  • 3 ½ cups powdered sugar, sifted
  • 1 ½ teaspoons pure vanilla extract (for frosting)
  • 2 to 3 tablespoons heavy cream or whole milk (for frosting)
  • 1 teaspoon edible pearl dust or shimmer powder
  • Pinch of salt (for frosting)

Instructions

  1. Preheat oven to 350°F (175°C). Line a 12-cup muffin tin with paper cupcake liners.
  2. In a medium bowl, whisk together flour, baking powder, and salt.
  3. In a large bowl, beat ½ cup softened butter and granulated sugar with an electric mixer on medium speed until pale and fluffy, about 3-4 minutes.
  4. Beat in eggs one at a time, then mix in 2 teaspoons vanilla extract. Scrape sides of bowl to combine.
  5. Reduce mixer speed to low. Add dry ingredients in three additions, alternating with ½ cup whole milk, starting and ending with dry ingredients. Mix until just combined.
  6. Spoon batter into liners, filling about ⅔ full.
  7. Bake for 14-16 minutes or until a toothpick inserted in the center comes out clean. Cupcakes should be lightly golden and spring back when pressed.
  8. Cool cupcakes in pan for 5 minutes, then transfer to a wire rack to cool completely before frosting.
  9. For frosting, beat 1 cup softened butter on medium speed for 2-3 minutes until creamy.
  10. Gradually add powdered sugar and a pinch of salt, mixing on low until combined.
  11. Mix in 1 ½ teaspoons vanilla extract and 2 tablespoons heavy cream. Beat on high for 3-4 minutes until fluffy. Adjust consistency with more cream or powdered sugar if needed.
  12. Gently fold in 1 teaspoon edible pearl dust or shimmer powder until evenly dispersed.
  13. Frost cooled cupcakes using a piping bag with a star tip or a knife. Optionally, dust extra shimmer on top.

Notes

Use room temperature ingredients for best results. Do not overmix batter to avoid tough cupcakes. Cool cupcakes completely before frosting to prevent melting. Refrigerate buttercream if too soft and re-whip before piping. For gluten-free option, substitute flour with 1-to-1 gluten-free blend. For dairy-free, use coconut oil and coconut cream. Dust shimmer powder at the end for best sparkle effect.
