Colorful Homemade Jello Cookies

Colorful Homemade Jello Cookies

If you can make sugar cookies than you can make Jello cookies! These colorful and flavored cookies can be customized with any color and cut into fun shapes. We made both traditional round cookies and magical unicorn cookies! My kids had a blast helping and of course, eating our creative snacks!

How to make Jello Cookies

1 cup sugar
1.5 cups softened butter
2 eggs
1 teaspoon vanilla
3.5 cups flour
1 teaspoon baking powder
Several packages flavored Jell-O

Cream together the sugar and butter until light and fluffy. Mix in the eggs and vanilla and stir until smooth. In a separate bowl mix together the flour and baking soda and add it to the sugar and butter mixture a little at a time. Stir and then knead the dough until the ingredients are fully combined. Separate your homemade sugar cookie dough out into small bowls and mix in 2 tbsp. of flavored Jell-O powder per bowl. Turn out onto a piece of parchment paper and knead the dough until combined.

Form 1 1/2 inch cookie dough balls on a parchment paper lined cookie sheet and slightly flatten each ball. If you are making sugar cookie shapes, roll out a quantity of Jello cookie dough until about 1/4 inch thick and cut out the shapes with a cookie cutter. Allow the cookie dough balls or shapes to chill on the baking sheet in the refrigerator for 30 minutes before baking.

Bake your homemade Jello cookies for 8 to 9 minutes in the oven at 350 degrees. Remove the cookies from the oven and allow them to cool on the baking sheet for a few minutes before moving each Jello cookie to a wire rack to fully cool. Enjoy!

Baking mishaps to avoid

Don’t roll out your sugar cookies too thin if you are making shapes. Chilled 1/4 inch thick cookie shapes baked for the proper amount of time turn out beautifully!

Don’t bake your Jello sugar cookies when the dough is too warm. They will flatten out too much in the oven and become a goopy mess.

Don’t over bake your cookies, set the timer for 8 minutes and check them. Bake for another minute if needed.

Don’t allow your cookies to stay on the hot cookie sheet too long once removed from the oven. Your sugar cookies may over bake and turn brown around the edges.

Don’t try to decorate your Jello cookies with icing until they are fully cooled. A bit of patience will produce gorgeous cookies!

Yummy Jello flavored sugar cookies

Our flavored sugar cookies and colorful unicorn shaped Jello cookies turned out so cute! These would be prefect for a kids birthday party or special occasion. We made them for fun to enjoy as a snack. I accented the unicorn cookies with purple icing and decorative sugar pearls. Kids can easily help bake these cookies as a creative afternoon activity. Which flavors will you choose?

Magical unicorn cookies are the best! Thanks for including mishaps to avoid, I tend to overbake and overcook literally everything I ever prepare, so it’s good to be reminded not to do that.


What an adorable idea. My niece would love these. And they bake super quick too – 9 minutes is fab!


This is very interesting, those colours look really happy! I didn’t know what Jell-o meant, is that a kind of gelatine?
