Instruction

  • Preheat oven to 350 degrees F. Prepare two cupcake tins by lining with paper liners.In a large mixing bowl or the bowl of a stand mixer, combine flour, sugar, baking powder, and salt. Mix to combine. Add butter and 1/2 cup of buttermilk. Mix on low speed until flour is evenly moistened, then increase speed to medium-high and beat until light and fluffy, 1 to 2 minutes, scraping down the sides of the bowl as needed.In a small bowl, beat remaining 1/4 cup buttermilk with eggs and vanilla. Add to the batter mixture one-third at a time, mixing well after each addition. Stir in sprinkles. Scoop a scant 1/4 cup (or use a large cookie scoop) to divide batter, filling each cavity about 2/3 full.Bake for 18 to 20 minutes, until tops are lightly golden on the edges and a toothpick inserted near the center comes out clean. Transfer pans to a wire cooling rack for 10 minutes, then remove cupcakes from pans to cool completely.To prepare frosting, in a large mixing bowl, beat butter on medium-high speed until smooth and fluffy, 2 to 3 minutes. Add powdered sugar, 1/2 cup at a time, mixing well after each addition. As frosting thickens, add a few tablespoons of cream as needed. Depending on the temperature and consistency of your frosting, continue alternating additions of cream and powdered sugar, until frosting is light and fluffy. Add vanilla and food coloring and beat until evenly incorporated. Spread or pipe onto cooled cupcakes; top with more sprinkles, if desired.
