The Best Texas Sheet Cake Cookies

"When I first started thinking about WHAT to make for this crazy, crazy as in awesome, week of #Choctoberfest I could not get Texas Sheet Cake Cookies out of my head. Why? I guess I wanted a chance to make something I’d never eaten before and that not everyone else would be making. I wanted new and different to eat and I found what I was looking for in Texas Sheet Cake Cookies. Before these cookies, I’d only ever made a Texas Sheet Cake once."
