How to Make Rainbow Jello Sugar Cookies
Preheat your oven to 175°C (350°F) and line your baking trays with parchment paper. This helps prevent sticking and makes for easy clean-up later.
Cream softened butter and granulated sugar in a mixing bowl for 3-4 minutes, until the mixture is light and fluffy. This process incorporates air, giving your cookies a perfect texture.
Add in the egg and vanilla extract, beating until well combined. This step ensures your cookies have a rich flavor and moist texture.
Whisk together the flour, baking soda, baking powder, and salt in a separate bowl until well-combined. This will help evenly distribute the dry ingredients throughout the dough.
Combine the dry mixture with the wet ingredients gradually, mixing until a smooth dough forms. Be careful not to overmix; you want to maintain that lovely texture in your cookies!
Divide the dough into four equal portions. Mix in different flavors of jello powder into each portion, creating colorful variations for your Rainbow Jello Sugar Cookies.
Shape the dough into 2.5 cm balls and roll them in granulated sugar. This not only adds sweetness but gives your cookies a beautiful, sparkly exterior.
Place the dough balls on the prepared baking trays, spacing them apart to allow for spreading. Bake in the preheated oven for 8-10 minutes, just until the edges are golden but the centers remain soft.
Cool your cookies on the trays for about 5 minutes before transferring them to a wire rack to cool completely. This helps set their shape while keeping them deliciously soft.
Optional: For an extra touch of fun, sprinkle an additional layer of colorful sugar on top before baking.

Tips for the Best Rainbow Jello Sugar Cookies
• Flavor Experimentation: Don’t be afraid to mix and match jello flavors to create unique combinations. This keeps things fresh and exciting every time you bake.
• Dough Consistency: If your dough feels too soft and sticky, chill it for about 15 minutes before baking. This prevents excessive spreading and helps maintain the cookie shape.
• Avoid Overbaking: For soft cookies, keep an eye on your baking time. The cookies should be lightly golden on the edges, while the centers remain soft.
• Storage Solutions: Store your Rainbow Jello Sugar Cookies in an airtight container at room temperature for up to a week. This keeps them fresh and delicious!
• Rolling Tips: When rolling dough balls in sugar, roll them well to ensure a nice sugary crunch on each cookie. This enhances the delightful texture!
Make Ahead Options
These Rainbow Jello Sugar Cookies are perfect for meal prep enthusiasts! You can prepare the cookie dough up to 24 hours in advance by mixing all the ingredients and dividing the dough into portions with the jello flavors mixed in. Simply wrap each portion tightly in plastic wrap and refrigerate them. This not only saves time on busy days but also allows the flavors to meld beautifully. When you’re ready to bake, just roll the chilled dough into balls, coat them in sugar, and bake as directed. This way, you’ll enjoy fresh, colorful cookies just like they were made that day, maintaining their soft and chewy texture!
