Monster Cookies

Giant cookies filled with peanut butter, oatmeal, chocolate chips, and M&M candies are the perfect treat. Don’t you think? This recipe is one that has stood the test of time. I first posted about these cookies in 2009 but figured an update was due. I based my recipe off my Great Grandma Nona’s recipe. She used flour in her recipe which I left out in mine and added in some more oats to help keep the cookies together. The result is a wonderful chewy oatmeal peanut butter cookie.

She was a wonderful baker and cook. She actually worked for many, many years as a lunch lady in the Spencer, IA schools, so she had tons of experience. This was back in the day when lunch ladies actually cooked and prepared real lunches instead of heating up processed food like most school cafeteria workers have to do today.

Oatmeal Monster Cookies

This current batch of monster cookies was baked for the teachers and staff at the girls’ school. Last week was teacher and staff appreciation week at the school and PTA parents brought in baked goodies for the teachers and staff to enjoy in the staff lounge. I took an informal poll on my Facebook page wondering what your favorite cookie flavor was. Monster cookie won hands down. So I delivered monster cookies to the school and you get to benefit from an updated recipe with clearer directions! Win-win.

If you use certified gluten-free oats all your gluten intolerant friends can indulge in the peanut butter and chocolate goodness of these chewy cookies too. Remember sharing is caring. If you are looking for certified gluten-free oats check out Bob’s Red Mill. I really like the easy availability of their products in the grocery store. Plus they do have the option of ordering directly from their website. I haven’t been compensated to say this I just really like their products. 

These cookies freeze beautifully if you want to save them.

  1. Monster cookies are also awesome straight from the freezer!!! My kids loved them that way in the hot hay field!
    Have you ever made the Doubletree cookies?

    1. Kath -I haven’t tried that recipe yet. I have come across it several times maybe one of these days I will finally give it a go.

  2. Oh my goodness! A fabulous looking cookie recipe with no flour. I’m going to have to try these. I’ve made the flourless peanut butter cookies and added oatmeal to them but these have even more wonderful things added in.
