Anyone that grew up in Iowa City will tell you that the monster cookie at Cookies & More in the Old Capitol Mall is the all-time greatest cookie. I have been testing monster cookie recipes for years trying to crack the code. I finally got it (it’s not an oatmeal cookie with peanut butter, it’s a peanut butter cookie with oatmeal). My sister-in-law, Katherine, tested the recipe and said the only thing it lacks is awkward adolescence and the mall smell.
If using Jif/Skippy peanut butter instead of natural peanut butter, add an extra 1/2 cup quick oats to the recipe.
- 1 cup butter, room temperature
- 1 1/4 cups natural peanut butter
- 1 cup brown sugar
- 1/2 cup white sugar
- 1/4 cup honey
- 1 1/2 tsp vanilla extract
- 2 eggs
- 1 cup all-purpose flour
- 1 tsp. baking soda
- 1/2 tsp. baking powder
- 1/2 tsp. salt
- 1 1/2 cups quick oats
- 1 cup chocolate chips
- 1 1/2 cups M&Ms
Cream butter, peanut butter, sugars and honey together until very light and fluffy, scraping down the bowl as needed, until the mixture is uniform in color.
Beat in eggs, one at a time. Scrape bowl.
Sift flour, soda, powder and salt and add to mixer. Stir until well combined, scrape bowl and mix well. Add oats and chocolate chips and mix well, scraping if necessary. You CAN mix in the M&Ms at this point, but if you want to be able to see them perfectly on top, reserve M&Ms until you have scooped the cookies.
Using about 3 TBSP of dough per mound, scoop the dough into mounds on a cookie sheet or plate that you can fit in your refrigerator to chill. Press 5-6 M&Ms onto the top of each mound. Chill at least an hour, or overnight.
When ready to bake: Preheat oven to 350 degrees. Transfer cookie dough balls to a parchment lined baking sheet, spaced about 3″ apart (you can roll them slightly into a more uniform ball at this point if you are into that sort of thing). Press each cookie down to flatten slightly.
Bake for 12-15 minutes until the edges are starting to brown. The center will look slightly under-baked. Cool completely on cookie sheets- they will fall apart if you try to remove them too quickly, but will firm up as they cool.
Repeat with remaining dough, or freeze dough balls and bake on demand. The cookies can be baked from frozen, you will just need to lengthen the baking time by 5 minutes or so.
