Ingredients

For the Cupcakes:

  • 1 cup all-purpose flour (186g)
  • 1 teaspoon baking powder
  • 1/2 teaspoon salt
  • 1/2 cup unsalted butter (melted, 113g)
  • 1 cup granulated sugar (200g)
  • 3 large eggs
  • 1 teaspoon vanilla extract or vanilla bean paste
  • 1/2 cup buttermilk (or combine 3/4 cup milk + 1 teaspoon white vinegar)
  • 1/2 cup rainbow sprinkles (132g)

Instructions

How to Prepare Birthday Cupcakes

  • Preheat your oven to 350°F (175°C).
  • Line a muffin tin with cupcake liners.
  • In a mixing bowl, whisk together the all-purpose flour, baking powder, and salt.
  • In another bowl, combine the melted butter and granulated sugar. Beat them together until light and fluffy.
  • Add the eggs one at a time, mixing well after each addition, then stir in the vanilla extract or vanilla bean paste.
  • Gradually mix in the buttermilk until the batter is smooth.
  • Slowly add the dry ingredients to the wet mixture, stirring gently until just combined.
  • Gently fold in the rainbow sprinkles.
  • Scoop the batter into the prepared muffin tin, filling each liner about two-thirds full.
  • Bake in the preheated oven for 18-20 minutes, or until a toothpick comes out clean.
  • Let the cupcakes cool in the tin for 5 minutes, then transfer to a cooling rack.
