"bought a fundraiser container of monster cookie dough and the hubbie stated it was awful. i found this recipe and had all ingredients on hand. just taking the last pan out of the oven now and i just threw away the rest of the awful tub of dough from the fundraiser. these are EXCELLENT!! hubbie likes them crispy so i baked them a few minutes longer for him. i like mine chewy and the baking time is spot on. tasty, not crumbly, easy dough to work with after the chilling time. thinking of making ice cream sandwiches with them for a summer treat."

"These are soooo good. Followed the recipe exactly EXCEPT one of the grand kids does not like raisins. I used chopped dates. Used baking M&M's., and a mixture of milk choc and dark choc chips. They were gone so fast. Made them for the nursing home for the residents and they loved them. I have a propane stove and it took a tad longer to bake. After 6 minutes reversed the tray front to back and baked for an aditional 6 to 8 minutes. Came out soft in the center and light brown on the edges. Used a large scoop as I thought using a measuring cup slower."

"I made these today. Oh my the smell of peanut butter permeating throughout the house is amazing. These cookies are the perfect amount of crunchy and soft. I didn't not use the corn syrup, instead I used molasses. I also used dark chocolate chips instead of semi sweet."

"Have been making these for myself, our senior adult Sunday school class and work for many years. At work, most are around 30 years old and eat these instead of the donuts that are brought in. Marathon and triathlon runners asks for these because mine are high in protein and complex carbs. I add chopped walnuts, use dark chocolate chips, no M & M's, use coconut sugar instead of brown sugar, coconut oil in place of butter and a Truvia in place of sugar. This way they have a very low glycemic index as well for those who are diabetic or anyone who wants to reduce sugar intake."

"I have made this cookie for 30 years and it does not have corn syrup in it! If you don't make the whole batch and put the extra dough in the fridge the oatmeal expands and there is more dough than you started with, lol."

"Made this today, followed someone's else's suggestion and used half a cup of flour also did not use the corn syrup. Worked beautiful. Thank you

Edit: second batch, used half a cup of flour and cut the cooking time to 12 mins. Made a lot of difference, the cookies are chewy insides and crispy outsides :-)"

"These cookies are excellent! The fact that these don't have any flour in them is a definite plus for those with wheat allergies. The only substitution I made was to use agave syrup instead of corn syrup due to a corn allergy. I used a medium scoop and baked them for 12 minutes with excellent results. Definitely a keeper!"

"I found the dough would not hold together when I made it by the recipe. They were raw in the middle and too brown at the edges. I added 1/2 cup flour and made them smaller, and I got a more satisfactory result."
