Ingredients

• 3/4 cup butter, cut into chunks
• 1 3/4 cups graham cracker crumbs
• 1/4 cup unsweetened cocoa powder (Hershey's)
• 2 tablespoons sugar
• 14 ounces sweetened condensed milk
• 6 ounces semisweet chocolate chips
• 1 cup raisins or miniature marshmallows
• 1 cup chopped nuts

Instructions

1. Preheat oven to 350 degrees F.
2. Place the butter in a 13-by-9-inch baking pan. Heat in the oven until melted; remove the pan from the oven.
3. Stir together the crumbs, cocoa and sugar. Sprinkle evenly over the butter. Pour the sweetened condensed milk evenly over the crumb mixture. Sprinkle with the chocolate chips and raisins. Sprinkle nuts evenly over top and press down firmly.
4. Bake for 25 to 30 minutes, or until the top is lightly browned.
5. Set the pan on a wire rack and cool completely. For firmer cookies that are easier to cut, cover pan with foil and let stand at room temperature for 6 to 8 hours. Using a sharp knife dipped in warm water, cut into bars.
