These Jello cookies are one of my favorite colorful baking projects to make with kids. They’re messy and fun, bake up beautifully bright, and taste fantastic. Instead of relying solely on food coloring like typical sugar cookies, these use dry Jell-O mix for both vivid color and real fruit flavor. The cookies turn out soft, fluffy, and bursting with flavor.

Cookies Made with Jello
These Jell-O sugar cookies aren’t just pretty — they actually taste like the flavors they show. I split the dough into five portions and add a different Jell-O flavor and matching gel color to each. You’ll get a rainbow of cookies tasting like strawberry, lime, lemon, orange, and berry blast. The Jell-O powder is fully incorporated so the color and fruit flavor run through every bite.
For variety, try combining colors for a marbled effect or freezing shaped dough balls for easy bake-ahead treats. A short chill keeps the cookies from spreading and preserves their bright hues, so they come out soft, tender, and vibrantly colored every time.

Chill the Dough for Perfect Cookies
Chilling the dough before baking is essential for round, fluffy Jell-O sugar cookies. Freezing shaped dough balls for 15 minutes firms them up, lets the cornstarch take effect, prevents excess spreading, and helps the colors stay vivid during baking.

Jello Cookies Recipe
Equipment
-
Kitchen scale (optional)
-
Hand mixer or stand mixer
-
2 baking sheets
-
Cookie portion scoop
Ingredients
- 3 cups all-purpose flour
- 1 teaspoon baking soda
- 1 teaspoon cornstarch
- ½ teaspoon kosher salt
- 1 cup unsalted butterslightly melted (2 sticks)
- 1 cup granulated sugar
- 2 large eggs
- 2 teaspoons pure vanilla extract
- 5 tablespoons dry Jell-O mix
- Gel food coloring
Instructions
-
In a medium bowl, whisk together the flour, baking soda, cornstarch, and salt. Set aside.
-
In a large bowl, beat the slightly melted butter and granulated sugar with a hand mixer until light in color, about 2 minutes.
-
Add the eggs and vanilla to the butter mixture and beat until light and fluffy, about 1 minute.
-
Add the flour mixture to the butter mixture and beat on low just until combined. Do not overmix.
-
Divide the dough into five bowls (about 187 grams per bowl if measuring by weight).
-
Sprinkle 1 tablespoon of dry Jell-O powder into each bowl, using a different flavor for each portion.
-
Add a drop of gel food coloring to each bowl to deepen the shade (red for strawberry, green for lime, orange for orange, yellow for lemon, blue for berry blast) and stir the Jell-O and color into the dough with a spatula or clean hands.
-
Preheat the oven to 350°F and line a baking sheet with parchment paper.
-
Using a 2-tablespoon cookie scoop, portion dough into balls (about 30 grams each) and roll into smooth balls. Arrange on a tray and freeze for 15 minutes to firm.
-
Line a second baking sheet with parchment. Place chilled cookie balls 3 inches apart and bake one tray at a time for 12–13 minutes. Centers may look slightly soft — they’ll finish on the hot tray.
-
Let cookies cool on the tray for 15 minutes before transferring to a wire rack to cool completely.
Notes
Tips:
- Measure flour using the spoon-and-level method to avoid dense cookies.
- The recipe uses 5 tablespoons total of Jell-O powder, divided among the five portions. Use any flavors you like.
- If you want less artificial dye, try Jell-O Simply Good or natural colorings (beet juice, butterfly pea powder, matcha), or reduce/eliminate added gel food coloring for softer pastels.
- Do not overwork the dough to prevent rubbery cookies.
- Slightly underbaking keeps the cookies soft and preserves vibrant color; browning will dull the hues.
- If bottoms brown too much, gently remove the browned layer with a grater.
Make-Ahead: Scoop dough balls, freeze them on a tray, then store in a sealed bag for up to 2 months. Bake from frozen, adding a minute or two to the bake time.
Storage: Store in an airtight container at room temperature up to 3 days, in the refrigerator up to 5 days, or frozen up to 1 month. Freeze in a single layer until solid, then transfer to a bag. Thaw at room temperature before serving.
How to Make Jello Sugar Cookies Step-by-Step
Prep: Gather the ingredients. Slightly melt the butter in the microwave for about 30 seconds.

Mix the Dry Ingredients: In a medium bowl, whisk together 3 cups all-purpose flour, 1 teaspoon baking soda, 1 teaspoon cornstarch, and ½ teaspoon kosher salt. Set aside.

Mix the Wet Ingredients: In a large bowl, beat 1 cup slightly melted unsalted butter and 1 cup granulated sugar until light, about 2 minutes. Add 2 large eggs and 2 teaspoons vanilla and beat until fluffy, about 1 minute.

Divide the Dough: Add the flour mixture to the butter mixture and mix on low until just combined. Divide the dough into five bowls (about 187 grams each if using a scale). Sprinkle 1 tablespoon of dry Jell-O into each bowl.

Color the Dough: Add a drop of gel food coloring to each bowl (red, green, orange, yellow, blue) and stir the Jell-O and color into the dough thoroughly. Kids enjoy this step, but gel coloring can stain — use aprons and wipes for easy cleanup.

Shape and Chill: Preheat the oven to 350°F and line a baking sheet with parchment. Scoop dough with a 2-tablespoon scoop into balls (~30 grams each) and roll smooth. Freeze the tray of dough balls for 15 minutes to firm.

Bake: Line a second baking sheet with parchment. Place chilled cookie balls 3 inches apart and bake one tray at a time for 12–13 minutes. Remove from oven while centers are still slightly soft and let cool on the tray 15 minutes before transferring to a wire rack.

How to Store
Store Jello cookies in an airtight container or Ziplock bag at room temperature for up to 3 days, in the refrigerator up to 5 days, or in the freezer up to 1 month. Freeze in a single layer until solid, then transfer to a sealed bag. Thaw at room temperature before serving.
