How to Make Jello Cookies
Step 1: Preheat and Prep
Start by preheating your oven to 350°F. Line a large baking sheet with parchment paper to ensure your Jello Cookies bake evenly and release easily. Trust me, this little step makes clean-up delightful, too!
Step 2: Cream the Butter and Sugar
In a large mixing bowl, cream together the softened butter and sugar with a hand mixer until the mix is fluffy and light in color. This is your secret to that perfect, melt-in-your-mouth texture. Beat in the egg and vanilla until smooth and fully combined.
Step 3: Combine the Dry Ingredients
In a separate bowl, whisk together the flour, baking powder, baking soda, and cream of tartar. Whisking aerates the flour and helps distribute the leaveners so your cookies rise evenly with every batch.
Step 4: Mix Wet and Dry Ingredients
Gradually add the whisked dry mixture to your bowl of creamed ingredients. Mix on low speed, just until a soft dough forms. Be careful not to overmix, as this keeps your cookies tender and delicate.
Step 5: Divide and Flavor the Dough
Divide the dough evenly into four sections—one for each Jello flavor you’re using. Each portion is about to transform! Sprinkle two tablespoons of Jello powder onto each section, then knead gently by hand until the color and flavor are evenly distributed. For extra wow factor, add a couple of drops of matching food coloring.
Step 6: Roll and Coat
Pinch off small, 1-inch balls of dough and roll them smoothly in your hands. Next, give them a playful toss in either additional Jello powder or plain sugar to coat them—this step delivers that signature sweet crunch on the outside.
Step 7: Shape and Bake
Place your cookie dough balls on the prepared baking sheet, leaving about two inches around each for spreading. Gently press down on each ball with the bottom of a glass to flatten—a classic Jello Cookie touch! Bake for 8 to 10 minutes until just barely set but still soft in the center.
Step 8: Cool and Enjoy
Carefully transfer the baked cookies to a wire rack to cool completely. As they rest, the cookies will firm up just enough while staying supremely soft in the middle. Now’s the time to grab a glass of milk and taste the joy you just baked!
How to Serve Jello Cookies

Garnishes
Jello Cookies love to dress up! Sprinkle them with colorful sanding sugar while still warm, or drizzle with a light glaze for an extra pop. If you’re feeling really festive, decorate with tiny candies or edible glitter for a celebration-ready batch.
Side Dishes
These cookies pair perfectly with classic cold milk, or try them with fruity teas for an elevated afternoon snack. For parties, set out a platter of Jello Cookies alongside bowls of fresh berries and a scoop of vanilla ice cream—simple, but unforgettable!
Creative Ways to Present
Arrange your cookies by color like a rainbow on a big platter or stack them in clear treat bags tied with ribbon for edible party favors. You could even sandwich a swirl of whipped cream or buttercream between two cookies for a homemade, Jello Cookie whoopie pie!
Make Ahead and Storage
Storing Leftovers
Keep Jello Cookies fresh by storing them in an airtight container at room temperature. They’ll stay soft and flavorful for up to five days—if they last that long without being devoured!
Freezing
Want to make ahead? Freeze the baked cookies by layering them in a freezer-safe container separated by wax paper to avoid sticking. They’ll keep beautifully for up to three months and thaw in minutes at room temp.
Reheating
If you like your cookies just-baked warm, pop them in a 275°F oven for 2-3 minutes or give them a quick zap in the microwave for about 10 seconds. The flavors bloom and the texture is pure bliss!
FAQs
Can I use different brands of gelatin for the Jello Cookies?
Absolutely! While classic Jell-O adds that nostalgic flavor, any store-brand gelatin powder in your favorite flavors will work and bring your cookies to life.
Do I need to add food coloring for vibrant Jello Cookies?
The Jello powder usually gives a gorgeous tint, but a drop or two of food coloring can bump up the vibrancy if you want truly electric colors. Totally optional—and lots of fun for themed occasions!
How do I keep my Jello Cookies soft and chewy?
Be careful not to overbake them; pull them from the oven when the edges are just set. Storing in an airtight container quickly after cooling also preserves their perfect buttery texture.
Can I make Jello Cookies gluten free?
Yes! Substitute your favorite gluten-free all-purpose flour blend for regular flour. Just be sure it includes xanthan gum or another binder to keep the dough together nicely.
What’s the best way to mix multiple flavors in one batch?
Divide the dough and knead in different flavors and colors separately. For extra fun, you can even swirl two colors lightly together in one ball for a marbled effect—totally eye-catching!
