Monster Cookies

This recipe combines several favorite flavors—peanut butter, butterscotch and chocolate—in one big cookie. Before baking, I like to press a few extra M&M's on top for added color. —Patricia Schroedl, Jefferson, Wisconsin

    These cookies were horrible. I could not find my Monster cookies recipe and I knew a Taste of Home recipe would be good. The cookies were so dry and crumbly before and after baking. This was an expensive waste of ingredients. I'm still trying to figure out how to salvage the rest of the dough.

    These are a hit, and I've made them a few times. One note: don't use crunch peanut butter. I did that recently but it seemed to make the cookies "dry."

    These were a big hit at my baby's dedication gathering! I've renamed "Many Blessings" cookies cause they are packed with lots of good things! Only alternation to the recipe I made was I did not add the peanuts cause I don't like nuts in stuff. So, instead of peanuts, I put in 1 cup of white choc chips. :o) They were a hit!

    NO flavor...they were soooo bland. I followed the recipe exactly. Put them in airtight container overnight, next day they were as hard as a rock. SOOO disappointing!

    These are good, very peanut & peanut buttery. They aren't super sweet as far as cookies go. We made them 1/2 as big as the recipe says since our kids are smaller. Easier to handle if you put a few drops of water on your palms every 5 cookies or so.
