1. Preheat oven to 350°F. Line a cookie sheet with parchment paper.
2. Divide sugar cookie dough into 6 equal balls.
3. Color each ball of dough a rainbow color (red, orange, yellow, green, blue, purple). Knead gently until the color is evenly mixed.
4. Roll each colored dough ball into a long rope (about the same thickness).
5. Place ropes side-by-side on the cookie sheet in rainbow order, gently pressing edges together. Curve the dough into a rainbow arch shape. (You can also make several smaller mini rainbows.)
6. Bake for about 10 minutes, or until edges are just turning golden.
7. Cool for 5 minutes, then slice into wedges. Let cool completely before serving.

Kid-Friendly Tips

• Kids can help choose colors, knead dough, and roll the ropes
• If dough gets sticky, chill it 10 minutes or lightly flour hands
• Make mini rainbows so each kid can build their own cookie

Easy Variations

• Rainbow “clouds”: Add mini marshmallows on the ends after baking (press lightly while warm)
• Rainbow sprinkle cookie: Add sprinkles on top before baking
• Pot of gold: Serve with a few gold chocolate coins on the side

Notes

For the brightest colors, use gel food coloring. Avoid overbaking—take the cookie out when the edges are just lightly golden so it stays soft. Store in an airtight container.
