Mint Oreo Brownies with Mint Buttercream Frosting

These right here are going to blow your mind. If you like mint and chocolate I suggest you run to your grocery store and get the few things you need to whip these suckers up. I love the mint and chocolate combination so these were very hard to resist. Thankfully I have an office full of taste testers so I was able get their feedback. I popped these suckers down at a table in the main corridor with a post it note and watched as people walked to the kitchen and stopped to take one, and then on their way back with their coffee they stopped for another sliver. Ohhh trouble!



As lame as it is, I made a resolution this year to enjoy holiday’s more. I have been extra grouchy about holidays and the effort they are so I have been trying to dive into the celebrations more this year. I will have fun damn it! So I am throwing myself at St. Patrick’s Day and all things green with wild abandon this year. So expect a few more St. Patrick’s Day themed recipes and posts leading up to the booze soaked day.

Back to the important things… brownies. The mint Oreos provide a lot of minty flavor, plus they provide a lot of moisture from the cream. I suggest baking them until they are just set so they are super fudgy. The frosting makes the over the top minty. I liked topping the brownies with crushed Oreos so it gave everyone a hint as to what was inside the brownies.
