Ingredients

Scale
  • 1 cup (227 g) unsalted butter, browned and cooled
  • 3/4 cup (150 g) granulated sugar
  • 1/2 cup (100 g) light brown sugar, packed
  • 2 large eggs, room temperature
  • 2 teaspoons pure vanilla extract
  • 2 1/4 cups (270 g) cake flour
  • 1 teaspoon baking powder
  • 1/2 teaspoon baking soda
  • 1/2 teaspoon salt
  • 3/4 cup rainbow sprinkles
  • Optional: 1/2 cup white chocolate chips or milk chocolate chips
  • Optional: Substitute 1/4 cup cake flour with almond flour

Instructions

  1. Brown the butter: Place 1 cup unsalted butter in a medium saucepan over medium heat. Stir constantly with a wooden spoon until butter foams, browns, and smells nutty. Remove from heat and cool about 10 minutes.
  2. Mix sugars and eggs: In a large bowl, whisk together granulated sugar and light brown sugar. Add eggs one at a time, beating well after each. Stir in vanilla extract until smooth and slightly fluffy.
  3. Combine browned butter: Slowly pour cooled browned butter into sugar-egg mixture, whisking continuously until fully incorporated and glossy.
  4. Sift dry ingredients: In a separate bowl, sift together cake flour, baking powder, baking soda, and salt.
  5. Combine wet and dry ingredients: Gradually add dry ingredients to wet mixture. Fold gently with a rubber spatula until just combined; avoid overmixing.
  6. Fold in sprinkles and optional chocolate chips: Gently fold in rainbow sprinkles and chocolate chips if using, distributing evenly without breaking sprinkles.
  7. Chill dough: Cover bowl with plastic wrap and refrigerate for at least 1 hour (30 minutes minimum).
  8. Preheat oven and prepare baking sheets: Preheat oven to 350°F (175°C). Line baking sheets with parchment paper or silicone mats.
  9. Portion and bake: Use a 2-tablespoon cookie scoop to drop dough mounds 2 inches apart on baking sheets. Bake 12-15 minutes until edges are set but centers are slightly soft.
  10. Cool on racks: Transfer cookies to cooling racks for about 10 minutes before serving.

Notes

Do not skip browning the butter for rich flavor. Chill dough to prevent spreading and achieve thick chewy texture. Avoid overmixing to keep cookies tender. Bake until edges are set but centers remain soft for best chew. Use sturdy sprinkles to avoid color bleeding. Store with a slice of bread in an airtight container to keep cookies chewy longer.
