Common Mistakes to Avoid
When making Gluten Free Flourless Monster Cookies, it’s easy to make a few common mistakes. Here are some tips to help you avoid them.

- Overmixing the dough – Overmixing can lead to tough cookies. Mix just until combined to keep them soft and chewy.
- Not measuring oats correctly – Oats should be leveled off when measuring. Too many oats can dry out your cookies.
- Ignoring baking time – Baking for too long can make your cookies hard. Take them out when they look set, as they will firm up while cooling.
- Not using parchment paper – Skipping parchment paper can cause sticking. Always line your baking sheet for easy removal and cleanup.
