Gluten-Free Option
This recipe has no flour making it really easy to make gluten-free! It also contains oats that are naturally gluten-free. If there are gluten-free restrictions, check the label on the oats to make sure they are made in a gluten-free facility.
There are also some great gluten-free options for chocolate chips out there. Most chocolate candies are gluten-free as well, just check the packaging before purchasing.

Easy to make Monster Cookies
This recipe is simple to make and it’s even great for beginner bakers. This cookie batter comes together in a matter of minutes without a whole lot of work.
To make these cookies even easier to make, I use silicone mats for non-stick and easy cleanup. One of my favorite tools when making cookies is my cookie scoop. It makes perfectly sized cookies and they are come out the same!
This recipe comes together very easily with very simple ingredients.

These are incredibly easy to mix, you don’t need a mixer. I use one because it’s quicker but it’s not necessary. You can do it by spoon or by hand. If you do make this recipe by hand -the trick is to make wide swipes in the bowl to thoroughly mix the ingredients.
You simply sprinkle and stir in the chocolate chips and M&M’s so you don’t over mix and break the pieces.

Can you freeze the dough? If so does it change the taste? Also, should I thaw them before baking or bake the frozen?

Yes, you can! I'd recommend scooping the dough and then freezing the dough balls in an airtight container. If stored properly the taste should not change. No need to thaw the dough first, just keep an eye on the cookies at the end of the baking time. :)

Amazing cookies!! I used chocolate chips and butterscotch chips instead of M&Ms, and only used about 1/2 bag of each and they turned out perfect. The dough seemed wet but the cookies didn’t spread too much, 13 minutes cook time was perfect. Once I took the cookies out of the oven and they cooled a little the middle looked a little wet, but they were cooked to perfection. Highly recommend!

Hey Jackie! Yup, they're supposed to look underbaked in the center... that's how you get that incredibly soft and chewy cookie! I'm so happy to hear that you enjoyed them!

Our neighbor, Kristin, sent these delicious cookies over earlier this month. She knows I like to freeze dough, and bake later. Kristen put dough balls in a ziploc freezer bag with a note on the bag of what to. I just baked these this morning, and they are delicious! I'm adding them to my baking recipes and sharing your site on my facebook page. Thank you for sharing these!

For some reason the cookies do not seem like they are done within the time frame it says which results in the bottom coming out a little burnt. Help.

Hi Isabella, The cookies should be soft in the middle. They still continue to bake once they are taken out of the oven.

My cookies are coming out completely flat. Is that normal? I'm frustrated cause I followed all the steps and idk when I could have gone wrong

Your butter may be a little too soft. You can chill the dough for about half an hour to prevent the cookies from spreading in the oven.
