Ingredients

Scale
  • 2 ½ cups (315g) all-purpose flour
  • 1 tsp (4g) baking powder
  • ½ tsp (2g) baking soda
  • ¼ tsp (1g) salt
  • 1 cup (227g) unsalted butter, softened
  • ¾ cup (150g) granulated sugar
  • ¼ cup (50g) light brown sugar, packed
  • 2 large eggs, room temperature
  • 2 tsp (10ml) pure vanilla extract
  • ¾ cup (125g) rainbow funfetti sprinkles
  • ½ cup (113g) unsalted butter, softened (for frosting)
  • 2 ½ cups (300g) powdered sugar, sifted
  • 1 ½ tsp (7ml) pure vanilla extract (for frosting)
  • 2 tbsp (30ml) whole milk
  • Pinch of salt

Instructions

  1. Preheat the oven to 350°F (175°C). Line two baking sheets with parchment paper or silicone mats.
  2. In a medium bowl, whisk together flour, baking powder, baking soda, and salt. Set aside.
  3. In a large bowl, beat softened butter with granulated sugar and light brown sugar until light and fluffy, about 3-4 minutes.
  4. Beat in eggs one at a time, then add vanilla extract until fully incorporated.
  5. Gradually add dry ingredients to wet ingredients, mixing on low speed just until combined. Avoid overmixing.
  6. Gently fold in rainbow funfetti sprinkles using a spatula.
  7. Drop dough balls (about 1 ½ tbsp each) onto baking sheets spaced 2 inches apart. Lightly flatten each ball to about 1/3 inch thickness.
  8. Bake for 10-12 minutes until edges are set but centers look slightly soft. Let cool on baking sheet for 5 minutes, then transfer to cooling racks to cool completely.
  9. While cookies cool, beat softened butter for frosting until creamy. Gradually add powdered sugar, vanilla extract, milk, and salt. Beat until smooth and fluffy.
  10. Spread about 1-2 tbsp frosting on the bottom side of one cookie, then press another cookie on top to form a sandwich. Repeat with remaining cookies.
  11. Optional: Chill sandwiches for 15 minutes to firm up frosting before serving.

Notes

Use room temperature butter for best creaming results. Fold sprinkles gently to avoid color bleeding. Refrigerate dough 15-20 minutes if too soft to handle. Watch baking time closely to keep cookies soft. Adjust frosting consistency with milk or powdered sugar as needed. Dough can be refrigerated up to 24 hours before baking. Freeze assembled sandwiches individually for up to 2 months.
