Colorful Jello cookies are a super fun treat to make for rainbow parties, with kids, or just for fun!
rainbow JELLO cookies
I’m in love with these vibrant, fun Jello cookies. Delicious, buttery sugar cookies are mixed with Jello powder to create a rainbow of flavors.
The cookie recipe calls for a generous helping of butter, so these are in the soft and chewy, “melt in your mouth” category of treats.

tools you’ll need to make rainbow cookies
You will need three baking trays. (If you do not have three, just be sure that the tray you are reusing is totally cool before adding cookie dough.)
A two tablespoon scoop, while optional, is fantastic for portioning cookies evenly.
I highly recommend lining baking trays with parchment paper.
While our recipes provide both the metric and non-metric amounts, a digital scale comes in handy with this recipe to divide the dough into four sections for four Jello colors.
I use an oven thermometer. (This is how I know my oven runs 25 degrees cold.)
JELLO of course! You’ll need the small size (3.5 ounces) of Jello in four colors. Any flavor blue, red, yellow, and green. I used Berry Blue, Strawberry, Lemon, and Lime.
Food coloring is optional, but to achieve the vibrant colors shown here, you will need just a few drops of coloring. I used Americolor brand gel paste food coloring:
TIPS to make Jello Cookies
Store in an air tight container for up to 5 days. You may also freeze the cookies up to 3 months.
Mixing in the Jello and food coloring
Knead in the Jello and Food coloring with your hands, OR use a standing mixer or electric mixer.
My preferred method is to use an electric mixer so my warm hands don’t overwork the dough. Wipe the bowl and beater clean with a paper towel after each color. If you make colors in this order, you minimize spreading one color to the next: Yellow, Green, Blue, Red/Pink.
While working with each color, keep the unused dough in the refrigerator.
You will NOT use all of the Jello powder.
Scooping the cookies
Use a 2-tablespoon scoop and roll the dough into a ball. Roll in extra jello powder.
