I’m going to tell you right off—make these! They are insanely good. Think of it as a black and white cookie but with half of it being a brownie cookie from here and the other half being the oatmeal cookie from here. From there I decided to give it a caloric pump by making it a monster cookie with added chocolate chips, Pretzel M&Ms, and chocolate covered pretzels.
I know caloric overkill, but that’s a theme here now and again—load up on the butter and sugar, then find your balance with the healthy savory recipes from around here. Yep, I have total polar opposite taste when it comes to sweet and savory.
Off the food subject, if you follow me on Instagram, than you know I shared the behind scene shot of shooting this set than shortly thereafter I checked in to deliver the newest addition of awesomeness to our family. Who by the way was probably was not so happy about me constantly bending over to style this shot, so he kicked his way out—well, at least he did 25 hours later from when he busted the water seal.
My point in telling you this . . . I had intended on reshooting on these, but life interrupted that, so these photos are as good as they get. And by the way, if you get lazy like I do when it comes to cookie making—just drop the two doughs in a jelly roll sheet and make this as dunking bars instead of cookies.

This is my ultimate hormonal PMS-y dream come to LIFE! Gorgeous!
Ahhh these cookies look fantastic! I’m such a sucker for Monster cookies and anything with M&M’s, so these are something I need to make ASAP, regardless of the fact that it’s practically summer beach time. More importantly though, congratulations on your newest addition of awesomeness! 🙂
These cookies look delicious! I love all the great flavors going on – so much fun!
These are amazing. You never have to decide between a cookie and a brownie again.
I think the kids will like it.
