- Preheat oven to 350°F (175°C). Line baking sheets with parchment paper.
- In a large bowl, cream together softened butter and 1 1/4 cups sugar until light and fluffy (approx 3 mins).
- Add the egg, egg yolk, and vanilla extract. Beat until well combined.
- In a separate bowl, whisk flour, cornstarch, baking soda, cream of tartar, and salt.
- Gradually add dry ingredients to wet, mixing on low speed just until combined.
- Gently fold in the sprinkles by hand using a spatula.
- Scoop dough into 1.5 tablespoon balls. Roll each ball in the reserved 1/4 cup sugar.
- Place on baking sheet 2 inches apart. Bake 9-11 minutes until edges are set but centers look soft.
- Cool on baking sheet for 5 minutes, then transfer to a wire rack.
Notes
Use jimmie sprinkles rather than nonpareils to prevent color bleeding.
