Ingredients

Scale

Base Dough

  • 1 cup (226g) unsalted butter, at room temperature
  • 1 1/2 cups (285g) granulated sugar
  • 2 large eggs, at room temperature
  • 1 teaspoon (5ml) pure vanilla extract
  • 3 ½ cups (420g) all-purpose flour
  • ½ teaspoon (2g) baking soda
  • ½ teaspoon (2g) cream of tartar
  • ¼ teaspoon (1.2g) salt

Add-ins and Decoration

  • ½ cup sprinkles
  • Gel colors (Pink, Royal Blue, and Violet)

Instructions

  1. Preheat Oven: Preheat your oven to 350°F (175°C) and line a cookie sheet with parchment paper or a silicone baking mat to prevent sticking.
  2. Cream Butter and Sugar: In a large mixing bowl, use a hand or stand mixer to beat the room temperature butter and granulated sugar together until the mixture is light and fluffy, about 3 to 5 minutes. This step helps incorporate air for a tender cookie.
  3. Add Eggs and Vanilla: Incorporate the two large eggs one at a time, mixing well after each addition, then add the vanilla extract and blend until fully combined.
  4. Combine Dry Ingredients: In a separate bowl, whisk together the all-purpose flour, baking soda, cream of tartar, and salt to evenly distribute the leavening agents and salt throughout the flour.
  5. Mix Dry Ingredients into Wet: Gradually add the dry ingredient mixture into the butter mixture, mixing on low speed until just combined to avoid overworking the dough.
  6. Fold in Sprinkles: Gently fold the sprinkles into the dough, ensuring they are evenly dispersed without breaking.
  7. Divide and Color Dough: Divide the dough into three equal portions. Tint each portion with a different gel color—pink, royal blue, and violet—kneading gently to distribute the color without overmixing.
  8. Swirl Colored Doughs: Lightly swirl the three colored dough portions together to create a marbled, tie-dye effect without fully blending the colors.
  9. Shape Cookies: Scoop portions of the marbled dough and roll them into balls. Optionally, roll the shaped dough balls in sugar or additional sprinkles for extra texture and sparkle.
  10. Bake: Place the shaped dough balls on the prepared cookie sheet spacing them about 2 inches apart. Bake in the preheated oven for 10-12 minutes or until the edges turn golden brown.
  11. Cool: Remove the cookies from the oven and transfer them onto a wire rack to cool completely before serving or storing.

Notes

  • Use room temperature butter for the creamiest texture and best dough consistency.
  • Avoid overmixing after adding the colors to maintain a distinct tie-dye marble effect.
  • If the cookies spread too much during baking, chill the dough for 20-30 minutes before baking to improve structure.
  • Use gel food colors instead of liquid to avoid altering the dough consistency.
