Instructions
 

For the Funfetti Cupcakes

  • See the "Notes" section below for high altitude instructions!
  • Preheat oven to 350°F and line a muffin tin pan with 12 cupcake liner. Set aside.
  • In a medium bowl, whisk together the flour, baking powder, baking soda and salt. Set aside.
  • In the bowl of a stand mixer fitted with the paddle attachment, or in a large bowl with a handheld mixer, beat the butter and sugar on medium speed until light and fluffy (about 5 minutes).
  • Add the eggs one at a time, beating with each addition until incorporated. Beat in the vanilla.
  • Turn the mixer to low and alternate adding the dry and wet ingredients, starting and ending with the dry ingredients. Mix until just combined.
  • With a sturdy spoon or spatula, mix in the sprinkles. Fill each liner three-fourths full with batter.
  • Bake cupcakes for 20-22 minutes or until a toothpick inserted into the center comes out with a few moist crumbs. Let cupcakes cool in the pan on a wire rack before frosting.

For the Chocolate Fudge Buttercream

  • In the bowl of a stand mixer fitted with the paddle attachment, or in a large bowl with a handheld mixer, beat the butter on medium speed until creamy (about 2 minutes).
  • Add the powdered sugar, cocoa powder, heavy cream, salt and vanilla and beat on low speed for 30 seconds. Increase the speed to high and beat until fully combined. Add ¼ cup of powdered sugar or 1 tbsp. of heavy cream as needed until the desired consistency is reached. Add an additional pinch of salt if desired. Pipe or spread onto cooled cupcakes and sprinkle with extra sprinkles. Enjoy!
