Ingredients

Scale
  • 1 cup (226 g) unsalted butter, softened
  • 1 cup (200 g) granulated sugar
  • 1/4 cup (55 g) brown sugar, packed
  • 2 large eggs, room temperature
  • 2 teaspoons pure vanilla extract
  • 1/2 teaspoon almond extract (optional)
  • 3 cups (375 g) all-purpose flour
  • 2 teaspoons cornstarch
  • 2 teaspoons baking powder
  • 1/2 teaspoon baking soda
  • 1/2 teaspoon salt
  • 2/3 cup (100 g) rainbow sprinkles (jimmies, not nonpareils)
  • For the Frosting (optional):
  • 1/2 cup (113 g) unsalted butter, softened
  • 2 cups (240 g) powdered sugar
  • 23 tablespoons (3045 ml) heavy cream or milk
  • 1 teaspoon vanilla extract
  • Pinch of salt (optional)
  • Extra rainbow sprinkles for topping

Instructions

  1. In a large bowl, beat 1 cup softened unsalted butter, 1 cup granulated sugar, and 1/4 cup packed brown sugar together for 2-3 minutes until light and fluffy.
  2. Beat in 2 large eggs, one at a time, scraping down the bowl as needed. Stir in 2 teaspoons vanilla extract and 1/2 teaspoon almond extract (if using).
  3. In a separate bowl, whisk together 3 cups all-purpose flour, 2 teaspoons cornstarch, 2 teaspoons baking powder, 1/2 teaspoon baking soda, and 1/2 teaspoon salt.
  4. Gradually add the dry ingredients to the butter mixture, mixing on low or by hand until just combined.
  5. Gently fold in 2/3 cup rainbow sprinkles with a spatula.
  6. Cover the bowl and chill the dough in the fridge for at least 30 minutes (up to overnight).
  7. Preheat oven to 350°F (175°C). Line two baking sheets with parchment paper or silicone mats.
  8. Use a large cookie scoop (about 3 tablespoons) to portion dough onto baking sheets, spacing about 2 inches apart. Press a few extra sprinkles on top if desired.
  9. Bake one sheet at a time for 10-12 minutes, until cookies are puffed and just starting to turn golden at the edges. Centers should look soft.
  10. Let cookies cool on the baking sheet for 5 minutes, then transfer to a wire rack to cool completely.
  11. For the frosting (optional): Beat 1/2 cup softened butter with 2 cups powdered sugar, 2-3 tablespoons cream or milk, and 1 teaspoon vanilla until fluffy. Spread on cooled cookies and top with more sprinkles.

Notes

Chill the dough for thick, bakery-style cookies. Use rainbow jimmies (not nonpareils) to prevent color bleeding. Don’t over-mix after adding flour. For extra-thick cookies, stack two smaller dough balls. Let cookies cool before frosting. Store in an airtight container for up to 4 days or freeze unfrosted cookies for up to 2 months.
