Very good!! My family loved them!! Makes a lot of cookies!! But well worth the time and effort.

I made these last night and they turned out great! I added about a 1/2 cup of shredded coconut, delicious. will be making them again. YUM

great cookies i used a whole bag of chocolate/caramel swirled chips and mini m&m's everyone loved them went really well. made a huge batch but will make them again and again

A very good and very easy to prepare recipe for Monster Cookies! Made these today b/c I was craving all sorts of flavors (I had a taste for PB, oatmeal, chocolate, butterscotch - you get the idea!). The only change I made was to add a little bit of everything I had on hand - butterscotch, semi-sweet, milk and white chocolate chips, M&M's (a couple packages of candies are fine - no need to buy a large bag of baking bits). I was able to clear out a lot of odds and ends in my pantry (hooray!) These are now my "everything but the kitchen sink" "monster" cookies (monster b/c they DO make a MONSTER batch - perfect for bake sales). Used a large cookie scoop (3 T.) to form cookies and baked for 13.5 minutes and they came out uniform in size and chewy. Goes great with a tall glass of cold milk : ) Oh, and these keep well - a little crisp, but easily softened when dipped in liquid. Thanks!

I wanted to point out that an 18 oz. jar of peanut butter equals 2 cups (not 1 1/2 cups like another reviewer posted). So you'll need one and a half 18 oz. jars of peanut butter to equal the 3 cups needed for this recipe. I like to use the crunchy kind. Great recipe!!

Awesome recipe, mine didn't go flat. Mine are good looking cookies, contrary to other reviews. Made the cookies into balls and flattened them only slightly on a parchment-lined cookie sheet. Baked them at 350 for 10 mins and let them finish cooking for 2 more mins on the cookie sheet out of the oven. In my experience using parchment is key to turning out great cookies. They are crunch on the outside and chewy in the centre. Made half a batch and it almost overflowed my kitchenaid mixer. I would not have wanted to try and mix this by hand, it is a very stiff dough. Also used chocolate chips only, no m&ms.

These cookies are GREAT!! I didn't alter anything and they came out perfectly. My fiance and our roommates loved them. They might not be the prettiest cookies but, they aren't ugly, they look just like oatmeal raisin cookies and they are not too chewy and not too crunchy. I will absolutely be making these again.

My first batch of cookies tasted a little bit on the blah side. I would have given the recipe 2-3 stars except that I did find a way to save them (which was fortunate since I don't know what I would have done with such an enormous amount of batter). I ended up using every last bit of leftover Christmas baking "stuff" ( butterscotch chips, chocolate swirl chips, peanut butter m&ms, semi-sweet chocolate chips, milk chocolate chips, mini m&ms, peanut butter chips). Yeah. That definately made them great! I will now call this my Everything cookie. It really was great, especially with the butterscotch chips to make them sweeter!

These are pretty good. I halved the recipe, because I didnt need 6 dozen cookies :) I also, added a 1/4 C raisins! yum!

This does take awhile. They are truely monsterous! Very good recipe. We liked them "just" baked. The one pan we over-baked was a little hard, but still tasty. Added this one to the "recipe box"!!!

These were pretty good. I wanted to use up some peanut butter and oats, so it worked for that! The mixture almost overflowed my Kitchenaid; it makes a ton! Our family wasn't able make a dent in them, so my husband took them to work and they were polished off in no time.

This was fantastic! I had to have my husband stir in the last 3 cups of oats, and the choco chips and M&Ms, but I baked all of them. . that took about 1.5 hours! Yum!! These are for a bake sale at church. . .you can't go wrong with monster cookies for a bake sale! I have 6 dozen to sell, and still more than 3 for my family to enjoy! Thank you!

My Grandma gave me this recipe years ago, my cousin & I have a picture of us making htese in our jammies when we were about 13. They were so much fun. I make them now every christmas for the cookie exchange in our neighborhood. Its easy- not so fast- but certainly fun! I make the original recipe that calls for the 18C of oats.... I type the recipe up & turn it into a christmas card to go along with the christmas plate of cookies i give.

I have had this recipe in my collection for years. The only difference is mine calls for 2 tablespoons of maple syrup instead of the 1 1/2 teaspoons of corn syrup. These are chewy and rich and are the cookie I'm asked most for at work.

I found this exact recipe in my church cookbook - each time I've made it, it has been too runny, so I added 1 cup of flour for 1/2 batch. My recipe also called for 3 1/2 cups of brown sugar. Maybe less would have helped. My kids loved the cookies and sure couldn't keep them for long! They make great gifts!

a fantastic cookie, an instant hit. these have now become my #2 favourite cookie behind my mom's chocolate chip cookies.
