Ingredients
Method
Preparation
- In the bowl of a stand mixer, beat the butter and granulated sugar on medium speed for about 2 minutes until light and fluffy.
- Add in the vanilla extract and egg. Mix until just combined.
- While the mixer is on low, gradually add in the corn starch, baking soda, baking powder, salt, and all-purpose flour. Mix until just incorporated.
- Gently fold in the rainbow sprinkles using a spatula or mixing spoon.
- Line a baking sheet with parchment paper. Using a medium-sized cookie scoop, scoop dough onto the sheet. Cover with plastic wrap and chill in the refrigerator for 30 minutes.
- Toward the end of chilling, preheat the oven to 350°F (175°C). Line two baking sheets with parchment paper.
- Arrange the chilled dough balls on the baking sheets about 2 inches apart.
Baking
- Bake for 10-12 minutes, or until the edges are just set.
- If desired, use a round cookie cutter to gently scoot cookies into shape. Cool on the sheet for about 5 minutes before transferring to a wire rack.
Notes
Store cookies in an airtight container at room temperature for up to a week. Can freeze dough for up to 3 months.
