Rocky Road Bars
Makes 16 - 2-inch bars
7 tablespoons unsalted butter, melted
1-1/2 cups fine graham cracker crumbs
1/4 cup sugar
1 cup walnut halves or large pieces
12 regular marshmallows, quartered
1 cup milk chocolate or semisweet chocolate chips
Preheat oven to 350 degrees. Position racks in the upper and lower thirds of the oven. Line the bottom and all 4 sides of an 8-inch square pan with foil.
Mix the butter with the graham cracker crumbs and sugar until everything is moist. Turn the mixture into the lined pan and spread it evenly, pressing very firmly all over the bottom to form a crust. Scatter half the nuts evenly over the crust.
Bake on the lower rack for 10 minutes, or until golden brown. Remove from oven and scatter the marshmallows, chocolate chips and remaining nuts evenly over the crust. Turn the oven temperature to 375 degrees, return the pan to the oven on the top upper rack and bake for 10-12 minutes, until the marshmallows are golden brown and merged with one another. Set on a rack to cool completely.
Lift the ends of the foil liner and transfer the bars to a cutting board. Use a long sharp knife to cut into 16 2-inch bars. May be kept in an airtight container for 4-5 days.
