Ingredients

Scale

Cookie 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

Decoration and Coloring

  • ½ cup sprinkles
  • Gel food colors: Pink, Royal Blue, and Violet

Instructions

  1. Preheat Oven: Set the oven to 350°F (175°C) and line a cookie sheet with parchment paper or a non-stick mat to prepare for baking.
  2. Cream Butter and Sugar: In a large bowl, beat the butter and sugar together until the mixture is light in color and fluffy in texture; then incorporate the eggs and vanilla extract thoroughly.
  3. Combine Dry Ingredients: Whisk together the all-purpose flour, baking soda, cream of tartar, and salt in a separate bowl to evenly distribute the leavening agents and seasoning.
  4. Mix Dry and Wet Ingredients: Slowly add the dry ingredients into the butter mixture, blending until a uniform dough forms without overmixing.
  5. Add Sprinkles: Gently fold in the sprinkles to distribute them throughout the dough for colorful bursts in every bite.
  6. Divide and Color Dough: Separate the dough into three equal portions; tint each one individually with gel food colors—pink, royal blue, and violet—using a small spatula or your hands.
  7. Create Marbled Effect: Combine the three colored dough portions by lightly swirling them together to create a vibrant, marbled pattern without fully blending.
  8. Shape Cookies: Scoop dough balls about 1 to 1.5 inches in diameter and optionally roll them in additional sugar or sprinkles for an extra decorative touch.
  9. Bake: Place the shaped dough balls on the prepared cookie sheet, spacing them about 2 inches apart, and bake for 10 to 12 minutes until the edges turn a light golden brown.
  10. Cool: Remove from the oven and let the cookies cool on the baking sheet for 5 minutes before transferring to a wire rack to cool completely.

Notes

  • Use gel food coloring rather than liquid to avoid altering the dough consistency.
  • Do not overmix the colored doughs when swirling to maintain distinct marbled patterns.
  • Cooling completely on a wire rack ensures crispy edges and a tender center.
  • Store cookies in an airtight container at room temperature for up to 5 days.
  • Butter should be softened but not melted for optimal creaming texture.
