Homemade Funfetti Cupcakes

Ingredients:

Cupcakes

  • 1 and 2/3 cups all-purpose flour
  • 1/2 teaspoon baking powder
  • 1/4 teaspoon baking soda
  • 1/2 teaspoon salt
  • 1/2 cup (1 stick) unsalted butter, melted
  • 1 cup granulated sugar
  • 1 large egg
  • 1/4 cup yogurt (plain or vanilla; or greek yogurt; or sour cream)
  • 3/4 cup milk (cow's milk; or soy milk; or almond milk)
  • 2 teaspoons vanilla extract
  • 1/2 cup rainbow jimmies/sprinkles (not nonpareils)

Vanilla Buttercream

  • 3/4 cup (170g) unsalted butter, softened to room temperature
  • 3 cups (360g) confectioners' sugar
  • 1/4 cup (60ml) heavy cream or half-and-half*
  • 2 teaspoons vanilla extract
  • salt, to taste

Directions:

  1. Preheat oven to 350F degrees. Line muffin tin with 12 cupcake liners. Set aside.
  2. In a medium bowl, mix together flour, baking powder, baking soda, and salt. Set aside. In a large microwave-safe bowl, melt butter in the microwave. Whisk in sugar - mixture will be gritty. Chill in the refrigerator for 1 minute. Stir in egg, yogurt, milk, and vanilla extract until combined. Slowly mix in dry ingredients until no lumps remain. Batter will be thick. Slowly stir in sprinkles, but do not overmix because the sprinkles will bleed their color.
  3. Divide batter among 12 cupcake liners (or 24 mini) and bake for up to 20 minutes or until a toothpick inserted in the center comes out clean. Bake for 8-9 minutes if making mini cupcakes. Allow to cool.
  4. For the frosting: in a medium bowl, beat the softened butter on medium speed with an electric or stand mixer fitted with a paddle attachment. Beat for about 3 minutes until smooth and creamy. Turn mixer off and add confectioners'  sugar, cream, and vanilla extract. Mix on low for 1 minute then increase to high speed and beat for 3-4 full minutes. Add more powdered sugar if frosting is too thin or more cream if frosting is too thick. Add salt if frosting is too sweet (I usually add 1/4 teaspoon). Frost cooled cupcakes and top with sprinkles.
  5. Store cupcakes in an airtight container at room temperature for up to 3 days and in the refrigerator up to 5.
