S’mores Brownies with a Graham Cracker Crust

This month’s Improv Challenge theme was to create a dish using the ingredients Chocolate and Marshmallows. S’mores lovers will be delighted with these S’mores Brownies…a crumbly graham cracker crust topped with a fudgy brownie and toasted marshmallows.

We spent many family vacations camping out west…and when we weren’t camping we were picnicking  around a roaring campfire. We hit most of the National Parks: Banff, Yellowstone, the Grand Tetons, Rocky Mountain, the Grand Canyon…all in either our Plymouth station wagon without a radio or air conditioner or the Big Blue Dodge van. S’mores were always a given when we were dining outdoors. I liked mine charred and gooey all the way through. But these S’mores Brownies are so much better than their rustic inspiration. Totally irresistible!

A Home Run with This S’mores Dessert

My youngest was home from college when I made these, and they sure disappeared fast. He has not been impressed with dorm food thus far…I have a feeling this sort of treat does not make their menu.  I even sampled a couple…it’s the graham cracker crust that tempts me every time! If you’re a fan of s’mores inspired desserts, these S’mores Cookie Bars and S’mores Cookies are tasty, too.
