Monster cookies are the epitome of childhood in a cookie. Also called “everything but the kitchen sink” cookies, they have, well, pretty much everything you could ever want in a cookie inside! Peanut butter, oats, m&ms, smarties (for Canadians :D), chocolate chips, skor bits, the possibilities are endless!

Last week I tried these Earth Day Bars from my friend Jenn, and they were quite good (though I did something to them so mine were really dry, might have been the homemade “bisquick” mix). But when my husband saw them on the counter he said “What’s this?! Monster cookie bars?!?”, and a lightbulb went off in my head.

Why not try making monster cookies as a bar? If the cookies are that good, bars would be even MORE amazing! The challenge was on!

I dug up the recipe from my friend Darla‘s mom, Beccy (mom of 11!), from our homeschool home ec classes. I distinctly remember her teaching us to make these cookies in a church basement kitchen, creaming what must have been 9 cups or so of peanut butter, BY HAND! I can see myself wooden spoon stirring and stirring and commenting about the muscles people must have had before electric mixers :D Good times!

This recipe has been an old faithful cookie recipe, and I must say, as a bar, it totally upped the bar! Hee hee, get it?! I changed some of the amounts and in the end removed enough batter to make 9 large cookies so the pan wasn’t too full.

Press into a lightly greased 9×13 pan. (Drop by large spoonfuls onto greased cookie sheet for cookies – I took out batter for about 9 large cookies).

Bake for 25-30 minutes (8-10 minutes for cookies).  They may seem underdone, but they’re perfect this way!
Give them a taste test. Go on, see if you can stop eating them.
