Prep Time 30 minutes
Cook Time 12 minutes

Ingredients
  

  • 1 cup (226g) unsalted butter, room temperature
  • 1½ cups (285g) granulated sugar (+ extra for rolling)
  • 2 large eggs, room temperature
  • 1 tsp pure vanilla extract
  • 3½ cups (420g) all-purpose flour
  • ½ tsp baking soda
  • ½ tsp cream of tartar
  • ¼ tsp salt
  • ½ cup rainbow sprinkles
  • Gel food coloring: Pink, Royal Blue, Violet

Instructions
 

  • Preheat oven to 350°F (175°C). Line a baking sheet with parchment paper.
  • Beat butter and sugar on medium speed until light and fluffy, about 2–3 minutes. Add eggs and vanilla; mix until combined.
  • In a separate bowl, whisk flour, baking soda, cream of tartar, and salt. Add to the butter mixture on medium-low speed until a dough forms.
  • Fold in the sprinkles with a spatula.
  • Divide dough into 4 portions. Leave one plain; color the others pink, blue, and violet with gel food coloring.
  • Combine all doughs in one bowl and swirl gently - just 3–4 folds. Stop before the colors blend completely!
  • Scoop into balls and roll in granulated sugar. Place 2 inches apart on the baking sheet.
  • Bake 10–12 minutes until edges are just set. Cool on the pan for 5 minutes, then transfer to a wire rack.

Notes

  • Butter must be softened, not melted - this is key for thick, chewy cookies.
  • Use gel food coloring only for best color results.
  • If cookies spread too much, chill dough balls 30 minutes before baking.
  • Don't over-swirl the colors - a few folds is all you need for that beautiful marbled look.
