Can I use sugar-free Jello for these cookies?

Yes, you can use sugar-free Jello to make Rainbow Jello Sugar Cookies . The flavor and color will still show up beautifully, and you'll reduce the sugar content overall. Just be aware that sugar-free versions might bake a little differently, so monitor your cookies closely during the final minutes.

How do I keep the colors from mixing too much?

To keep the colors distinct, knead each dough color in its own bowl. If you want to swirl two colors, only blend them lightly—do not overmix. Also, chill the dough for 20–30 minutes before baking to help the colors set and avoid blending during baking.

Are these cookies safe for kids with allergies?

It depends on the specific allergens. Most Jello brands contain gelatin (an animal product), so they’re not vegetarian- or vegan-friendly unless a plant-based gelatin alternative is used. If you're baking for someone with food sensitivities, be sure to check all labels—especially on Jello, flour, and any decorations.

What’s the best way to keep them chewy?

Avoid overbaking! Pull the cookies from the oven when the edges are just set and the centers look slightly soft. Also, store them in an airtight container as soon as they’re fully cool. This preserves that iconic chewy texture that makes Rainbow Jello Sugar Cookies so irresistible.

Do I need to chill the dough before baking?

Chilling isn’t mandatory, but it's highly recommended—especially if your dough feels too soft or sticky after adding the Jello. A quick 30-minute chill makes the dough easier to handle and helps the cookies hold their shape and vibrant color in the oven.
