Jello cookies are the happiest, most colorful treat to make with kids and require only a handful of basic pantry ingredients. With bursts of fun flavors and a playful swirl of colors, these cookies brighten up snack time or a party tray in less than thirty minutes.
The first time my daughter and I tried these, her friends could not believe we used powdered gelatin to color and flavor the dough. Now we experiment with new combos every holiday.
Ingredients
- Snickerdoodle cookie mix in a bag: gives a light base with tender crumb Choose a reliable brand and skip the cinnamon-sugar packet
- Salted butter melted: adds rich flavor and moisture Go for high quality as it affects how creamy the dough is
- Large egg: binds everything together Fresh eggs work best for perfect texture
- Red flavored gelatin powder: brings bright color and classic cherry or strawberry taste Make sure it is fresh and lump-free
- Blue flavored gelatin powder: gives a cool hue and sweet berry flavor
- Green flavored gelatin powder: adds playful color and a fresh lime or apple taste
- Yellow flavored gelatin powder: brightens things with lemon or pineapple flavor
- Granulated white sugar: coats each cookie for sparkle and delicate crunch Always use fine sugar for even coverage
Step-by-Step Instructions
- Prep Your Oven and Pan:
- Heat your oven to 350 Fahrenheit and line a baking sheet with parchment or a silicone mat This stops sticking and makes for easy cleanup
- Mix the Cookie Dough:
- In a large bowl fully combine the bag of cookie mix melted butter and egg Use a wooden spoon and mix until everything looks uniform with no dry spots
- Divide and Color the Dough:
- Split the dough evenly into four separate bowls In each bowl knead in three tablespoons of a different color gelatin powder This is easiest and most fun with your hands The dough will become bright and fully colored as the gelatin incorporates
- Roll and Sugar the Dough:
- Pour the sugar into a wide shallow bowl Using a two tablespoon cookie scoop shape balls of dough from each bowl Coat each ball in sugar rolling until fully covered
- Bake the Cookies:
- Space the dough balls on the prepared pan at least two inches apart Bake for about twelve minutes You are looking for slightly firm tops with just a touch of gold If they darken much remove right away
- Cool and Enjoy:
- Let the cookies sit on the baking sheet for three to five minutes before transferring to a rack Enjoy them warm for gooey centers or cool for a crispier bite

My favorite part is rolling the dough in sugar that step brings back childhood memories of baking at my grandma’s house especially when we mixed and matched unexpected color combos
