Christmas Sprinkle Sugar Cookies

1 Preheat oven to 350°F (175°C) and line a baking sheet with parchment paper.
2 Cream the butter and sugars together for 2–3 minutes, until light and fluffy.
3 Add the egg and vanilla and mix until fully combined.
4 Whisk dry ingredients (flour, baking soda, salt) in a separate bowl.
5 Combine wet and dry ingredients until a soft dough forms. Fold in the sprinkles.
6 Scoop dough into 1½ tablespoon balls and place 2 inches apart on your baking sheet.
7 Chill for 20–30 minutes if your kitchen is warm (optional but helps prevent spreading).
8 Bake for 9–11 minutes, until the edges are just set and the centers look slightly underbaked.
9 Cool on the pan for 5 minutes, then transfer to a wire rack. They’ll firm up as they cool.
