    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.
