These gluten free funfetti cookies are soft, chewy, and bursting with color in every bite. Perfect for birthdays, parties, or anytime you need a sweet pick-me-up.
Preheat oven to 350F and line a large baking sheet with parchment paper.
In a mixing bowl, cream the softened butter and granulated sugar together for 2 minutes until light and fluffy. Add the egg and vanilla extract, beating until smooth.
Add the gluten free flour, cornstarch, baking soda, and salt. Mix on low speed until a soft dough comes together.
Gently fold in the rainbow sprinkles using a spatula so the colors don't bleed into the dough.
Scoop 1.5-tablespoon sized balls of dough onto the prepared baking sheet. Bake for 9-11 minutes. The centers should look slightly underbaked. Let them rest on the pan for 10 minutes before transferring to a wire rack.
