Ingredients

Scale
  • 1 1/2 cups all-purpose flour
  • 1 tsp baking powder
  • 1/4 tsp baking soda
  • 1/4 tsp salt
  • 1/2 cup unsalted butter, softened
  • 3/4 cup granulated sugar
  • 2 large eggs
  • 1 tsp vanilla extract
  • 1/2 cup sour cream
  • 1/4 cup milk
  • 1/2 cup rainbow sprinkles (jimmies)

Vanilla Buttercream Ingredients:

  • 1/2 cup unsalted butter, softened
  • 2 1/2 cups powdered sugar
  • 1 tsp vanilla extract
  • 2-3 tbsp milk or heavy cream
  • Extra sprinkles for garnish

Instructions

  • Preheat oven to 350°F (175°C) and line a muffin tin with cupcake liners.
  • In a medium bowl, whisk together the flour, baking powder, baking soda, and salt.
  • In a large bowl, cream the butter and sugar until light and fluffy.
  • Beat in the eggs one at a time, then mix in the vanilla extract.
  • Add the sour cream and mix until smooth.
  • Gradually add the dry ingredients, alternating with the milk, and mix until just combined.
  • Gently fold in the sprinkles, being careful not to overmix (to prevent the sprinkles from bleeding).
  • Divide the batter evenly into the cupcake liners, filling each about 3/4 full.
  • Bake for 18-20 minutes, or until a toothpick inserted into the center comes out clean. Let the cupcakes cool completely on a wire rack.
  • Frosting Instructions:
    1. Beat the butter until creamy, then gradually add powdered sugar, vanilla extract, and milk. Beat until smooth and fluffy.
    2. Pipe or spread the buttercream onto the cooled cupcakes and garnish with extra sprinkles.

Notes

  • Use jimmies-style sprinkles (long, soft sprinkles) rather than nonpareils, as nonpareils can bleed color into the batter.
  • Store the cupcakes in an airtight container for up to 3 days.
