Step by Step Instructions
Making glow-in-the-dark cookies is surprisingly simple. Here’s how to bring them to life pun intended!
1. Prepare the dough
In a medium bowl, whisk together the flour, baking powder, and salt. In a separate large bowl, cream together the butter and sugar until fluffy about 2–3 minutes. Beat in the egg, vanilla extract, and tonic water.
Gradually mix in the dry ingredients until a soft dough forms. If the dough feels sticky, add a little more flour. Divide into two discs, wrap in plastic, and chill for at least one hour.
2. Roll and cut
Preheat your oven to 350°F (175°C). Line baking sheets with parchment. Roll out one dough disc on a lightly floured surface to about ¼-inch thick. Use Halloween-themed cookie cutters to cut shapes and transfer to the baking sheet.
3. Bake
Bake for 8–10 minutes or until the edges are just turning golden. Let them cool on the sheet for a couple minutes before moving to a wire rack.
4. Make the icing
Whisk powdered sugar with tonic water and corn syrup. Adjust consistency with more sugar or water. Add food coloring and decorate your cooled cookies. Let icing set for at least 1 hour.
5. Test the glow
Turn on a black light and watch them glow! The quinine in tonic water reacts under UV light, creating the eerie glow effect.
Tips for Success
Want bakery-quality results every time? Here’s what works:
- Use room temperature butter for smooth mixing.
- Chill your dough. It helps the cookies keep their shape.
- Don’t overbake. Sugar cookies can dry out quickly.
- Let the icing dry fully before stacking or storing.
- For extra sparkle, top your icing with a little Caramel Apple Puppy Chow dust for sweet crunch.
Variations on Glow in the Dark Halloween Sugar Cookie Cutouts
Looking to put your own twist on it? Here are fun, beginner-friendly variations.
Gluten-Free Version
Swap the flour for a 1:1 gluten-free baking blend. Just be sure to chill the dough longer to avoid spreading.
Add a Streusel Topping
Before baking, sprinkle a light cinnamon streusel mix on top. It won’t glow, but adds flavor and texture. Try pairing it with these Healthy Pumpkin Oatmeal Bars for a spooky dessert spread.
Vegan Option
Use a plant-based butter and replace the egg with a flaxseed egg (1 tbsp ground flax + 2.5 tbsp water). Works great, though the dough may be a little softer.
Creative Cutouts
Instead of traditional shapes, try making spooky “eyeballs” with white icing and a candy pupil. Or mimic glowing bones using skeleton molds.
How to Store and Freeze
You’ll want these cookies to last especially if baking ahead for a party.
- At room temp: Store in an airtight container for up to 5 days.
- Refrigerated: Keeps for 1 week with icing intact.
- Frozen: Freeze unfrosted cookies up to 2 months. Thaw and ice before serving.
These are perfect to prep alongside other fall treats like Brown Sugar Pumpkin Loaf or Pumpkin S’mores Cookies for a dessert table that wows.
