I really liked these cookies. I went with some suggestions and substituted the margarine with peanut butter, otherwise I left the recipe the same. It gave it a hint of PB without being overpowering. My family gobbled them up! Cookies like these are why I don't bake anymore unless I'm baking for church or something. I couldn't stop at just one!!

Made the recipe as written, cookies were very good. Kids and husband loved them. Thanks!!

I didn't find these to be anything like a monster cookie. I cooked them and they came out very thin, and stuck to the pan. The only thing I could really taste in them was the chocolate.

I made these cookies for a co-workers going away party and everyone loved them. I'm even getting requests for the recipe. I halved the recipe, which was more than enough and substituted 3/4 cup peanut butter for a 1/2 cup margarine, 3 cups of quick oats instead of 2, 1 cup of flour instead of 2 and I added an extra tsp of vanilla. I also used 1 cup of mini semi-sweet chocolate chips and 1 cup of mini candy-coated pieces instead of the half the recipe recommends. Upon recommendation, I rolled the dough into golf ball size balls and smashed them down into neat circles with a spoon, baking 6 at a time. The size was perfect and the cookies turned out AWESOME. I did end up with a couple left; be forwarned that after 4 days, the cookies will be stale, however I look forward to making this recipe again and freezing some for the holidays. Thanks!

i'm guilty of not following the recipe exactly but instead the tips of others: bake at 325 degrees for 13 minutes, substitute peanut butter for margarine, halved the recipe (yield 4 dozen cookies!). tasted great right out of the oven but they were solid rocks the next day. there are much better recipes.

These cookies were so good! I did alter the recipe though...I halved it first off, and instead of butter subbed in peanut butter. Also, I cut out about 1/2 cup of flour and put in extra rolled outs instead. I added butterscotch chips in too, but wished I hadn't since they were the overpowering flavor (but still good!). They came out huge (I used an ice cream scoop, and didn't press the dough down at all once on the sheet), chewy and great looking!

My husband doesn't like chocolate, so I made a couple of changes. I replaced the 1/2 cup of margarine with 1/2 cup peanut butter. And I took out the chocolate chips and M&M's and used about a cup of Reeces Pieces instead. I followed a couple other reviewers in the cooking time--I baked them at 325 degrees for about 15 minutes and they were nicely browned but still soft and chewy inside. My husband took one bite and started saying how good they were! I halved the recipe and got a lot of cookies--12 JUMBO and about 15 regular/large size. This is my new favorite peanut butter cookie recipe! Thanks for sharing!

I have finally found 'MY' cookie recipe! Delish! This makes alot but is so easy to throw together because it is the perfect sized batch to fit in my big Kitchen Aid. And with no peanut butter or nuts it is ok for school lunches. I am taking some to 4H later on this afternoon.

This is my favorite cookie recipe! I've been making it for about 6 yrs. and I always get rave reviews. I substitute peanut butter for the margarine and make 1/2 recipe. I use the med. Pampered Chef scoop (about 2 T.) for each cookie and bake for 11 min.

THESE COOKIES ARE EXCELLENT! I was looking to make the same monster cookies you buy from Sobey's Bakery (IGA) and these have oatmeal, which I wasn't thrilled about at first... They are everyone's favourite... It makes 2 icecream pail's full and I've made them SEVERAL times -- Candy pieces-- Smarties are a must!!

ADDICTIVE. I half the recipe when i make these. Instead of margerine I use smooth peanut butter. These are really delightful.

Yummo!

Huge batch to make with original recipe. I may cut it in half next time. They worked out well for giving out some holiday cookies. Tasty chewy cookies with a great texture and flavor.

After looking at MANY different recipes and reading lots of reviews for this one on this site; I used several of the other's suggestions and this is what I came up with. I used 1 1/2 cups of peanut butter, 1 cup of butter, 2 3/4 cups of brown sugar, 3/4 cups of white sugar (this was plenty sweet for our taste). I increased vanilla to 2 Tbl. only used about 3 1/4 cup flour, increased the oatmeal to 5 cups and used half quick cooking and half regular. I also followed another's suggestion and ran this through my mini food processor. I used 1 cup of mini chocolate chips and 1 cup of mini M&M pieces, 1 cup of chopped pecans and 1 cup of coconut. Made golf ball size rolls, flattened slightly and baked for 11 minutes at 350. These came out looking really nice, not dry, held their shape and tasted great! Soft and chewy. I got 6 dozen out of my recipe with cookies about 3 inches across. I have never eaten Monster Cookies but I liked the idea of them having peanut butter and I followed another's suggestion and made a few tweaks of my own. That said, I still think they are a 5 star but since I made so many changes, I wasn't sure how to rate this. I think you could really just "play with" this basic recipe.

This was ALMOST 5 stars, because I think all monster cookies should have peanut butter! I followed the recipe and added a 1/2 cup of peanut butter when creaming the sugar, butter and eggs. They turned out fantastic, but I did have to bake them about 11 minutes to get chewy cookies. yum!

taste much better after freezing I found, will make again.

These are a very good cookie; a pleasant change from the usual choc chip. I followed the recipe as is, but next time I will increase the amount of M&M's and use mini choc chips as opposed to regular. My first batch was rather thin, so the following batches I increases the cookie size in hopes of having a chewier cookie. Looks good so far, but they aren't totally cool yet so they may still fall.

I made these once now every time my kids have a youth event, I'm asked to bring a batch. People who don't like oatmeal cookies are always surprised when that ask about what is in them. Thanks for giving me a fool proof recipe that makes lots of big cookies.
