Tips & Variations

• For a stronger glow, use tonic water with quinine and keep treats under UV light or blacklight.
• Try mixing different neon colors for a fun layered effect.
• Substitute the tonic water with regular water for non-glowing treats but keep the vibrant colors.
• Add sprinkles or candy eyes before the treats set to keep decorations firmly in place.
• Use large marshmallows chopped into small pieces if mini marshmallows aren’t available.

Storage

Store the treats in an airtight container at room temperature for up to 3 days to keep them fresh and chewy. Avoid refrigeration, as it can make them hard. For best glow, serve them fresh and keep away from prolonged exposure to sunlight.

FAQs

Will these treats glow without tonic water?

No, tonic water contains quinine, which is responsible for the glow effect under UV light. Without it, the treats will have bright colors but won’t glow.

Can I use regular food coloring instead of neon?

Regular food coloring works to add color but won’t create the vibrant neon look that enhances the glow. Neon food coloring is recommended for the best effect.
