  • All-purpose Flour: 4 cups
  • Cream of Tartar: 2 tsp
  • Baking Soda: 1 tsp
  • Salt: 1/2 tsp
  • Unsalted Butter: 1 cup, at room temperature
  • Sugar: 1 3/4 cups
  • Large Eggs: 2
  • Vanilla Extract: 1 tsp
  • Food Coloring: Red, orange, yellow, green, blue, and purple gel


  1. Mix Dry Ingredients:
    • In a mixing bowl, sift together the flour, cream of tartar, baking soda, and salt. Set aside.
  2. Cream Butter and Sugar:
    • In a large bowl, cream the butter and sugar with an electric mixer until the mixture is light and fluffy.
  3. Add Eggs and Vanilla:
    • Beat in the eggs one at a time, followed by the vanilla extract, ensuring each ingredient is fully incorporated.
  4. Combine with Dry Ingredients:
    • Gradually add the dry ingredients to the wet mixture, mixing until a cohesive dough forms.
  5. Color the Dough:
    • Divide the dough into six equal portions. Using gel food coloring, tint each portion a different color of the rainbow.
  6. Create Layers:
    • Roll out each colored dough separately between sheets of parchment paper to prevent sticking.
    • Layer the rolled-out doughs on top of each other. Gently roll over them with a rolling pin to slightly press the layers together.
  7. Form the Cookie Log:
    • Carefully roll up the layered dough tightly from one end to the other, creating a log shape.
  8. Slice and Bake:
    • Slice the log into 1/4-inch thick cookies. Place them on a lined baking sheet.
    • Bake in a preheated oven at 350°F (177°C) for 10-12 minutes or until the edges are just turning golden.
  9. Cooling:
    • Let the cookies cool on the baking sheet for a few minutes before transferring them to a wire rack to cool completely.

Tips for Success:

  • For intensely vibrant cookies, opt for gel food colorings which offer brighter colors without altering the dough’s consistency.
  • Ensure the cookies are fully cooled before handling to maintain their shape and prevent them from breaking.
  • Store the cookies in an airtight container at room temperature to keep them fresh and soft.

Conclusion: These Rainbow Swirl Cookies are a fun, festive treat that’s sure to impress. Whether for a special occasion or a creative weekend baking project, they bring a splash of color and a burst of joy to any cookie jar!
