How to Store Leftovers

Recipe Tips
- Use fresh marshmallows for the best gooey texture.
- Do not press the cereal too hard into the pan.
- Melt the candy in short bursts to avoid burning.
- Use a toothpick to make the tiny stitch details.
- For a party, double the batch for a crowd.
- Add a pinch of salt to balance the sweetness.
- Ensure the treats are cool before dipping in chocolate.
- Spray your spatula with oil to prevent sticking.
Ways to Switch It Up
- Swap green for purple to make different monsters.
- Use gluten-free puffed rice cereal if needed.
- Add chocolate chips to the cereal for extra crunch.
- Use white chocolate dyed with green instead of melts.
Common Questions
Can I make these ahead of time?
Yes, you can make them the day before your party. They stay soft and delicious in a sealed container. Just keep them in a cool spot.
What if I do not have gel food coloring?
Liquid coloring works but the green may be lighter. Gel gives you that vibrant monster neon look. Use a little extra if using liquid.
Will the pretzel sticks fall out?
Dip the ends in melted candy to act as glue. This helps them stay secure in the treats. It adds a nice salty crunch too.
I hope these little monsters bring joy to your Halloween. They are so much fun to make and eat with family. Happy haunting and happy snacking!
