Ingredients
Method
- Cream together butter and sugar on medium speed until light and fluffy, about 5 minutes. Mix in vanilla extract and egg until just combined.
- On low speed, add cornstarch, baking soda, baking powder, salt, then gradually add flour until dough forms. Gently fold in sprinkles last.
- Chill dough for at least 30 minutes if sticky. Preheat oven to 350°F (177°C), line baking sheets with parchment.
- Scoop dough into 2½ tablespoon balls, place spaced on baking sheets, let rest 5 minutes before baking.
- Bake 10-12 minutes until edges are just set and golden. Optional: shape warm cookies into perfect rounds with a glass. Cool 5 minutes on sheet, then transfer to racks.
Notes
Use thick “jimmie” sprinkles to prevent color bleed. Dough chills improve texture and flavor. For fluffy cookies, don’t skip creaming butter and sugar adequately.
