These cookies are also a great choice if you are looking for a flourless cookie. Make sure to use gluten free oats if you want to make the cookie truly gluten free.

- Add the the oats and mix until combined, then add the chocolate chips.
- Scoop dough onto the prepared baking sheets, spacing the mounds at least 2 inches apart. I use a 1/4 cup scoop.

Monster Cookie Tips

- Room Temperature – Having your ingredients at room temperature will help them to combine better.

This recipe doesn’t say when to add the corn syrup… Which meant it didn’t get added when creaming butter an sugars 🙁 I assume that’s when to add it?
Also, the instructions say to add salt, yet salt is not listed in the ingredients??Reply
Leigh Anne Wilkes says
Sorry about that – add the corn syrup in with the sugar and there is 1/4 tsp salt although I’ve made them without the salt too and they work fine.

These cookies are just wonderful! I had the opportunity to take dinner to a family in our ward who just had a new baby arrive last Friday and they have a wheat allergy. I was looking everywhere for a baked good to take with dinner that didn’t have flour and remembered this recipe 🙂 I’m so glad and greatful for you and your willingness to share your recipes!
