Ingredients
Dry Ingredients
- 2½ cups all-purpose flour
- 1 teaspoon baking soda
- ½ teaspoon baking powder
- ½ teaspoon salt
Wet Ingredients
- 1 cup unsalted butter, softened
- 1½ cups granulated sugar
- 1 large egg
- 1 teaspoon vanilla extract
- ½ teaspoon cotton candy extract
Flavor & Color
- 3 tablespoons cotton candy-flavored gelatin powder
- Neon food coloring (pink, blue, purple, green)
Fun Garnishes
- ½ cup cotton candy, torn into small pieces (for garnish)
- ¼ cup edible glow-in-the-dark sugar (optional but magical)

Instructions
Step 1: Preheat and Prep
Preheat your oven to 350°F (175°C) and line a baking sheet with parchment paper.
Step 2: Whisk the Dry Stuff
In a medium bowl, whisk together the flour, baking soda, baking powder, and salt. Set aside.
Step 3: Cream Butter and Sugar
In a large bowl, beat the softened butter and sugar together until light and fluffy—about 2–3 minutes.
Step 4: Add Eggs and Flavor
Mix in the egg, vanilla extract, and cotton candy extract. Stir until smooth and creamy.
Step 5: Add the Gelatin Powder
Mix in the cotton candy-flavored gelatin powder until fully incorporated. This adds color and flavor!
Step 6: Combine Dry and Wet
Gradually add the dry ingredients to the wet mixture, mixing just until a soft dough forms. Do not overmix.
Step 7: Divide and Color
Divide the dough into 3 or 4 portions. Tint each with a different neon food coloring and mix until fully colored.
Step 8: Swirl and Scoop
Take small bits of each colored dough and swirl them together by hand to form a multicolored ball. Don’t over-mix—you want those gorgeous color streaks. Roll into 1½-inch balls and place on your baking sheet.
Step 9: Add the Glow
Lightly press the edible glow-in-the-dark sugar onto the tops of each dough ball for a twinkly finish.
Step 10: Bake and Cool
Bake for 10–12 minutes, or until the edges are set but the centers are still soft. Let them cool on the baking sheet for 5 minutes before transferring to a wire rack.
Step 11: Garnish with Cotton Candy
Once completely cool, gently press a tuft of cotton candy on top of each cookie right before serving. (Add this step last—cotton candy melts with moisture.)
Tips for the Most Magical Cookies
- Don’t overbake! These are best soft and chewy in the middle.
- Add the cotton candy garnish just before serving to keep it fluffy.
- Use a blacklight at your party to show off the glow-in-the-dark sugar!
- Make them mini for bite-sized fun or jumbo for a dramatic treat.
FAQs
Where do I find glow-in-the-dark edible sugar?
Look for edible luster dust or UV-reactive sugar at baking supply stores or online. Just make sure it’s labeled food-safe!
Can I freeze the dough?
Yes! You can roll and freeze the dough balls (without sugar coating) for up to 2 months. Just bake straight from frozen—add 1–2 minutes to the bake time.
What if I can’t find cotton candy extract?
You can skip it and rely on the gelatin for flavor, or sub in a drop of vanilla or raspberry extract for a fruity twist.
Conclusion
These Glow-in-the-Dark Cotton Candy Cookies are pure joy in cookie form—bright, sweet, soft, and just a little magical. Whether you’re throwing a birthday bash, hosting a glow party, or just want to bring some sparkle to your kitchen, these cookies deliver.
