Servings and Nutrition
- Servings: 6–8 spider treats
- Calories: ~120 per serving (varies based on cotton candy size and candy eyes)
- Course: Dessert / Party Treat
- Cuisine: American / Halloween-themed
Ingredients
- 1 bag of cotton candy (any color, preferably neon or bright)
- Candy eyes (small or medium size)
- Black licorice strings or black edible sugar strands (for spider legs)
- Optional: tonic water spray (for glow under blacklight) or neon food coloring sprays
- Small skewers or toothpicks (for assembly, optional)
Step-by-Step Preparation
Step 1: Prepare the Cotton Candy
- Pull small portions of cotton candy into round spider bodies.
- Shape each portion gently into a puff that will serve as the spider’s torso.
Step 2: Add the Spider Legs
- Cut black licorice strings into equal lengths. You will need 8 pieces per spider.
- Insert or press 4 licorice strings on each side of the cotton candy puff to create the spider’s legs.
Step 3: Attach the Candy Eyes
- Place 2 candy eyes on the front of each cotton candy puff using a small dab of edible glue, frosting, or simply pressing lightly into the cotton candy.
Step 4: Optional Glow Effect
- Lightly spray the cotton candy with tonic water (quinine will glow under blacklight) or neon food coloring sprays.
- Place under a blacklight for a glowing effect.
How to Serve
Serve these spiders on a black or dark-colored platter to enhance the glow effect. You can scatter small fake spider webs around the platter for decoration. These are best enjoyed immediately, as cotton candy dissolves quickly in humid conditions.
Recipe Tips
- Work quickly – Cotton candy can dissolve if handled too long or exposed to moisture.
- Use small skewers – For taller presentation or easy handling at parties.
- Be gentle – Avoid pressing too hard, or the candy eyes may sink.
- Experiment with colors – Purple, green, or neon orange cotton candy adds a fun twist.
Variations
- Gummy Spider Legs: Replace licorice with thin gummy strips for a softer option.
- Mini Spider Web Cups: Place the spiders atop small cups of black frosting or pudding for a creepy “web effect.”
- Glittery Spiders: Lightly dust edible glitter on the cotton candy for extra sparkle.
- Party Favors: Wrap each spider in clear cellophane with a ribbon for take-home treats.
Freezing and Storage
- Storage: Cotton candy spiders are best served fresh; do not store in humid conditions.
- Freezing: Not recommended, as cotton candy loses its texture.
Special Equipment Needed
- Black licorice or edible sugar strands (for legs)
- Candy eyes
- Toothpicks or skewers (optional, for assembly)
- Blacklight (optional, for glow effect)
