You know what my favorite thing about a box of brownie mix is? The possibilities. 
I mean, sure. You could make some plain old brownies with that box of mix. Or you could add every possible good thing in life to that box of brownie mix and create something magical. (Sort of like I did with these Cadbury Creme Egg Brownies!)

This time around, I topped my brownies with plenty of chocolate chips and mini marshmallows. Then I went all crazy and created an easy peanut butter sauce to drizzle daintily over the top. And, okay, whatever. There was nothing dainty about it. I basically just dumped on as much sauce as possible and then buried my face in the pan of gooey goodness.
