Brown butter starts this recipe off, filled with lots of oats, M&M's and chocolate chips they are the perfect cookie. Bite-size these Brown Butter M&M Oat Cookies are dangerous to have around!

Two weekends ago I went down to San Diego for a Bachelorette night for one of my favorite bunnies ever! Ashley and I became friends through work and we have all become a little family at our pub. This cutie pie is getting married in about a month and I am so happy for her!

I went with 3 other girls, and since it was a road trip (more like 2 hours) I knew I needed snacks cookies for the drive. And since brown buttah is mah thing and I had a new bag of mini m&m, brown butter oat m&m cookies were made.
They were so good. Perfect size. Perfect texture. And chock a block full of m&ms and chocolate, a definite must in a cookie.

These cookies were fabulous, even at three o'clock in the morning. I won't lie this is great after the club snack 😉 This and a fresh quesadilla that is!

Notes
I personally brown butter in batches and keep some in fridge but if you can do it this way too.
