With just four simple ingredients plus colorful jello powder, you'll create a rainbow of cookies that will delight both kids and adults.

I first made these cookies for my daughter's rainbow-themed birthday party. The kids were mesmerized by the vibrant colors, and now they're requested for every special occasion in our home.
Ingredients
- Snickerdoodle cookie mix: 17.5 ounce bag provides the perfect cookie base and saves time on measuring dry ingredients
- Butter: 1/2 cup melted adds richness and helps bind the cookies
- Large egg: creates structure and helps the cookies rise properly
- Red jello powder: adds cherry or strawberry flavor and creates vivid red cookies
- Blue jello powder: perfect for creating blue raspberry flavored treats
- Green jello powder: lime flavor adds a refreshing tanginess to the green cookies
- Yellow jello powder: lemon flavor provides a bright citrus note
- Granulated white sugar: for rolling creates a sweet sparkly exterior
Step-by-Step Instructions
- Preparation:
- Preheat your oven to 350°F. This temperature creates the perfect environment for the cookies to spread slightly while maintaining their chewy centers. Line your baking sheet with parchment paper or a silicone mat to prevent sticking and ensure easy cleanup.
- Mix Base Dough:
- Combine the snickerdoodle cookie mix, melted butter, and egg in a large bowl. Stir thoroughly until no dry patches remain. The dough will be slightly thick and somewhat sticky. Make sure your butter has cooled slightly before adding the egg to avoid cooking it.
- Divide And Color:
- Separate the dough equally among four small mixing bowls. This is where the magic happens. For precise portions, use a kitchen scale or estimate by eye, dividing the dough into quarters.
- Add Flavor:
- Knead 3 tablespoons of each jello powder into each portion of dough. Use your hands for best results, working the powder completely into the dough until the color is uniform throughout. The dough will become vibrant and fragrant as you mix.
- Prepare Sugar Coating:
- Place 1 cup of granulated sugar in a shallow bowl. This will be used to coat the cookie balls before baking, creating a sweet, slightly crisp exterior that contrasts beautifully with the soft interior.
- Form Cookies:
- Use a 2 tablespoon cookie scoop to portion the dough. Roll each portion into a ball between your palms, then coat completely in sugar. The sugar not only adds sweetness but helps prevent the cookies from spreading too much.
- Bake To Perfection:
- Place the sugar coated balls on your prepared baking sheet, allowing 2 inches between each cookie. Bake for 10 to 13 minutes, watching carefully. The cookies are done when the tops become firm but not browned. Overbaking will result in crunchy rather than soft cookies.
- Cool And Enjoy:
- Allow the cookies to cool on the baking sheet for 3 to 5 minutes before moving. This resting period helps them set up properly. Enjoy warm for a gooey center or completely cooled for a chewier texture.

The blue raspberry jello cookies are my family's unanimous favorite. Something about that vibrant color combined with the sweet fruity flavor makes them disappear first every time I serve a mixed plate. My youngest always claims them before anyone else can grab them.
Storage And Freshness
These jello cookies maintain their soft texture and vibrant color for up to 5 days when stored in an airtight container at room temperature. Place sheets of parchment paper between layers to prevent sticking and color transfer. For longer storage, these cookies freeze beautifully for up to 3 months. Simply thaw at room temperature before serving. The colors may fade slightly over time, but the flavor remains delicious.
Flavor Variations
While this recipe calls for standard jello flavors, feel free to experiment with seasonal or unique options. Try watermelon for summer parties, grape for a deep purple cookie, or orange for Halloween treats. During holidays, match your cookie colors to the season. Christmas works beautifully with just the red and green batches, while patriotic celebrations call for red, white (plain dough), and blue cookies. You can even mix dough colors together for a marbled effect that creates stunning visual appeal.

Decorating Ideas
Take these cookies to the next level with simple decorations. Before baking, press a coordinating candy into the center of each ball. After baking and cooling, drizzle with a simple powdered sugar glaze in contrasting colors. For birthday parties, press a chocolate candy in the center immediately after baking for a melty surprise. You can also sandwich two cookies together with frosting for an extra special treat that showcases the vibrant colors.
