Method
step1: In a mixing bowl, beat the butter and granulated sugar together until light, fluffy, and creamy.
step2: Add the egg and vanilla extract. Mix until smooth and well combined.
step3: In another bowl, whisk together flour, cornstarch, baking powder, baking soda, and salt.
step4: Add the dry ingredients into the wet mixture. Mix until a soft cookie dough forms.
step5: Fold in the rainbow sprinkles gently to avoid color streaking.
step6: Cover the dough and chill for 20–30 minutes for thicker, softer cookies.
step7: Preheat the oven to 350°F (180°C) and line a baking sheet with parchment.
step8: Roll dough into balls (about 1½ tbsp each). If desired, press extra sprinkles on the outside for a festive look.
step9: Place on the baking sheet with space between cookies.
step10: Bake 9–11 minutes, until the edges look just set and the centers are still soft.
step11: Let cool on the tray for 5 minutes, then transfer to a cooling rack.
