I combined a couple recipes for these and I'm not sure that's a good thing--they are SOOO good, it may be dangerous! Super easy, stuff you usually have on hand, and a no-mess version of the s'more!
2 cups graham cracker crumbs
1 stick (1/2 cup) melted butter
1 cup sugar
2 cups chocolate chips
1/2 bag mini marshmallows (2 cups)
*Combine crumbs, butter and sugar. Spread half of the mixture into a greased 8x8 pan. Sprinkle chocolate chips over crust, then marshmallows. Sprinkle the remaining graham cracker crumb mixture over the top of the marshmallows. Bake at 350 degrees for 15-17 minutes, or until golden brown on top and bubbly. Enjoy! (You could easily double this recipe for a 9x13--nothing has to be super exact).
