Step 2
Make cookie dough
Cream butter and sugar until light and fluffy. Add egg and vanilla extract, mixing until combined.
Step 3
Combine dough
Gradually add dry ingredients into wet mixture until a soft dough forms.
Step 4
Divide and color
Split dough into equal portions and tint each portion with different gel food colors.
Step 5
Form swirl log
Roll each colored dough into thin sheets, stack them, and gently roll into a log. Chill until firm.
Step 6
Slice and bake
Slice chilled dough into cookies and bake at 175°C (350°F) for 8–10 minutes until edges are lightly golden.
Use gel coloring
Gel food coloring gives brighter rainbow tones without changing dough consistency.
Chill before slicing
Chilling the dough log helps maintain clean swirl patterns when slicing.
Pastel swirl cookies
Use lighter pastel tones for a softer aesthetic.
Chocolate swirl base
Replace part of the flour with cocoa powder for a chocolate twist.

Q: Why did my swirl cookies lose their shape?
A: The dough likely wasn't chilled long enough before slicing. Always chill until firm.
Q: Can I use liquid food coloring?
A: Gel coloring is recommended because liquid can make the dough too soft.
