How to Make This Recipe for Jello Cookies

This is a super simple recipe to prepare. After you make the cookie dough, all you have to do is separate it for each flavor of jello. This way you will have some jello sugar cookies of each color! We love this basic cookie recipe because it takes on new flavors very well.

Ingredients Needed to Make Jello Sugar Cookies

• Flour – all-purpose is best for these cookies
• Cream of tartar – This is needed to stabilize the egg whites and it helps the cookies rise in the oven when combined with baking soda.
• Baking soda
• Salt 
• Butter – Make sure it is softened before you start combining ingredients
• Granulated sugar – You will need a little bit extra to roll out the cookies
• Eggs – Let your eggs sit out on the counter and come to room temperature
• Milk
• Vanilla extract 
• Jello gelatin, you will need 2 tablespoons each  – Choose any 4 flavors you like! 

Instructions for Jello Cookies

Step 1

Preheat your oven to 350 degrees F.

Step 2

Prepare your baking sheets by adding parchment paper or a silicone baking mat. This will make it easy to get the cookies off of the pan after they’re baked.

Step 3

Mix your dry ingredients; flour, cream of tartar, baking soda, and salt in a medium bowl.

Step 4

Cream the butter and sugar together in a large bowl until fluffy.

Step 5

Add the wet ingredients; eggs, milk, and vanilla to the large bowl with your butter and sugar mixture.

Step 6

Next, slowly mix in the dry ingredient mixture with the wet ingredients.

Tip: Avoid overmixing and mix until just combined. This will prevent tough, flat cookies.

Step 7

Separate the cookie dough into 4 equal portions and place each in a separate bowl.

Step 8

Sprinkle the jello mix into each bowl (one flavor for each one) and knead gently until it’s combined.

Step 9

Use a cookie scoop or a tablespoon and scoop out the chilled dough and roll it into 1-inch balls.

Step 10

Add the extra sugar into a small bowl and roll each cookie dough ball in the sugar before placing it on the parchment-lined cookie sheet. Repeat this until all of the dough is used.

Step 11

Bake the cookies for about 8-10 minutes. You’ll know they’re done when the edges are slightly browned.

Step 12

Remove the baking sheet from the oven and let the cookies cool for at least minutes before transferring them to a wire rack so they can cool completely.

Step 13

Enjoy with a nice glass of milk and store leftovers in an airtight container.
