Instruction

  • Preheat oven to 350°F (176°C). Prepare a cupcake pan with cupcake liners. 2
  • . In a large mixing bowl, beat the butter and sugar together on medium speed until light in color and fluffy, 3-4 minutes.
  • . Add the sour cream and butter and vanilla extracts and mix until combined.
  • . Add egg whites in two batches, mixing until incorporated after each addition. Scrape down the sides of the bowl as needed to make sure everything is combined.
  • . Combine flour, baking powder and salt in a medium bowl. Combine the milk and water in a small measuring cup.
  • . Add half of the flour mixture to the batter and mix until combined.
  • . Add the milk mixture to the batter and mix until combined.
  • . Add the remaining flour mixture and mix until smooth. Scrape down the sides of the bowl as needed to ensure everything is being combined.
  • . Stir in the sprinkles.
  • 0. Fill cupcake liners about halfway. Bake for 15-17 minutes, or until a toothpick inserted comes out with a few crumbs
  • 1. Remove cupcakes from oven and allow to cool for 2-3 minutes, then remove to cooling rack to finish cooling.
  • 3. While cupcakes cool, make the frosting. Combine egg whites, sugar, and cream of tartar in a metal, heatproof mixer bowl. Place bowl over a pot with simmering water (You could also use a double boiler)
  • 4. Whisk constantly until sugar is dissolved and whites are warm to the touch, 3 to 4 minutes. Remove from heat.
  • 5. Using the whisk attachment, beat on low speed, gradually increasing to high, until stiff, glossy peaks form, 5 to 7 minutes.
  • 6. Frost the cupcakes (I used the large round Ateco 808 tip) and top with sprinkles. Add a little marshmallow popcorn treat to the top.
