Surprise Birthday Cake Cupcakes Ingredients

  • 1/2 Cup fresh milk
  • 1/2 tablespoon Vinegar
  • 1 1/2 cups all-purpose flour
  • 1 tablespoon cornstarch
  • 2 teaspoons baking powder
  • 1/2 teaspoon Salt
  • 2 large eggs
  • 1 Cup brown sugar
  • 1/2 Cup vegetable oil
  • 2 teaspoons vanilla extract
  • 3/4 Cup rainbow sprinkles
  • 1/2 Cup salted butter
  • 1 teaspoon vanilla extract
  • 3 cups Powdered SUgar sifted
  • 1/4 Cup All-purpose cream or as needed

Instructions
 

  • Preheat oven to 350 degrees F (180 degrees C). Prepare cupcake trays and line with cupcake liners. Make homemade buttermilk by combining fresh milk with vinegar. Allow the mixture to sit for 5 minutes before using. 
  • Over a large bowl using a strainer, sift flour, cornstarch, baking powder, and salt to remove lumps. Set aside. 
  • In another large bowl either by hand or with an electric mixer, beat eggs together with homemade buttermilk, oil, and vanilla extract. Add white sugar and mix until homogenous.
  • Slowly add sifted dry ingredients to the wet ingredients, making sure to mix slowly to combine. Add 1/4 cup sprinkles. Do not overmix.
  • Using an ice cream scoop, scoop batter into prepared liners in the cupcake tray, only filling up each liner until 2/3's full.
  • Bake for 19 to 24 minutes or until a toothpick inserted in the center comes out clean. Once done, remove cupcakes from the oven and allow to cool thoroughly on a wire rack. 
  • Once cooled, using a knife or the large end of a piping tip, make a hole in the center of each cupcake. Add 1 teaspoon of sprinkles into each cupcake. Seal the hole by returning the removed cupcake crumbs back into the hole. Set aside. 
  • Create buttercream frosting by beating butter on medium speed for 3 minutes. Add vanilla extract. Add powdered sugar 1/4 cup at a time until ideal consistency is achieved. (Thin out the frosting by adding the cream or thicken the frosting by adding more powdered sugar until desired consistency is achieved.) 
  • Frost cupcakes once entirely cool. Top with extra sprinkles and serve.
