Equipment

  • 9x13 baking dish
  • Medium bowl
  • Large Mixing Bowl
  • Electric Mixer
  • circle cookie cutter
  • piping bag

Ingredients

  • 2 ¼ cups all-purpose flour
  • 2 teaspoons baking powder
  • ½ teaspoon baking soda
  • ½ teaspoon salt
  • ¾ cup unsalted butter softened
  • 1 ½ cups granulated sugar
  • 3 large eggs
  • 2 teaspoons vanilla extract
  • ¾ cup sour cream or plain Greek yogurt
  • ¾ cup milk
  • ¾ cup red and green sprinkles jimmies work best

Frosting:

  • 1 cup unsalted butter softened
  • 3 ½ cups powdered sugar
  • 3 tablespoons milk or heavy cream
  • 2 teaspoons vanilla extract

Instructions

  • In a medium bowl, whisk flour, baking powder, baking soda, and salt.
  • In a large bowl, cream butter and sugar until light and fluffy. Beat in eggs one at a time, then mix in vanilla.
  • Add sour cream, then alternate adding dry ingredients and milk until just combined. Gently fold in sprinkles.
  • Spread batter evenly into the prepared pan and bake 25–28 minutes, or until a toothpick inserted in the center comes out clean. Cool completely.
  • While cooling, prepare frosting: beat butter until smooth, then gradually add powdered sugar, milk, and vanilla until fluffy.
  • Once cake is cool, use a round cookie cutter (about 2–3 inches wide) to cut out circles. Stack 2 layers with frosting between each.
  • Frost the top of each mini cake and decorate with holiday sprinkles.

Notes

  • Use red & green jimmie sprinkles so colors stay bright (avoid ones that bleed).
  • A 9×13 pan, parchment lining, and full cooling time are key.
  • Stack same‑sized rounds for uniform mini cakes.
  • For gifting: wrap each in a little box or clear bag with ribbon.
Storage Directions
  • Storing: Keep leftovers in an airtight container in the refrigerator for up to 3‑4 days.
  • Make‑ahead: You can bake the sheet cake a day ahead, wrap it tightly, and refrigerate. Then cut and frost on the day of serving.
