Top Tips for Perfect Cookies

Storing & Reheating

FAQs: Your Rainbow Cookie Questions, Answered! 

Got questions? We’ve got answers! Here’s everything beginners (and cookie enthusiasts!) need to know about mastering these colored sugar cookies:

1. Can I use liquid food coloring instead of gel?

Technically, yes—but we strongly recommend gel food coloring. Liquid dyes can water down the dough, making cookies spread too thin or lose their soft texture. Gel colors pack a vibrant punch without messing with the recipe’s balance. If you’re in a pinch, use liquid sparingly (think: 2–3 drops max per color).

2. Why did my cookies turn out crispy instead of soft?

Overbaking is the usual culprit! These cookies bake FAST—they’re done when the edges just start to turn golden (even if the centers look slightly underdone). They’ll firm up as they cool. Also, check your oven temperature with a thermometer; ovens often run hotter than they claim.

3. Can I make the dough ahead of time?

Absolutely! Prepare the dough, divide and color it, then wrap each ball in plastic wrap. Refrigerate for up to 3 days or freeze for 3 months. Let chilled dough sit at room temp for 15 minutes before rolling and baking.

4. How do I prevent colors from bleeding together?

Work quickly when rolling dough balls, and wash your hands between colors. If your kitchen is warm, pop the colored dough portions in the fridge for 10 minutes to firm up before shaping.

5. Are these cookies kid-friendly?

100%! Little hands love squishing the dough and mixing colors. For extra safety, use natural food dyes (like beet powder or turmeric) if you’re avoiding artificial colors.

6. Can I make these gluten-free or vegan?

Gluten-free: Swap all-purpose flour 1:1 with a GF blend (we love King Arthur’s).
Vegan: Use plant-based butter and replace the egg + yolk with ¼ cup unsweetened applesauce or a flax egg.

7. My cookies spread too much—what went wrong?

Possible reasons:

• Butter was too soft (it should be slightly cool to the touch).
• Dough was overmixed (develops gluten, leading to spread).
• Oven wasn’t preheated (always preheat for 10–15 minutes!).

8. Can I skip the rainbow and use just one color?

Of course! Turn these into unicorn cookies with pastels or go bold with a single neon shade. They’re your cookies—rule the rainbow (or ditch it)!
