Brownies
["6 oz. unsweetened baking chocolate", "1 c. butter", "2 c. sugar", "4 large eggs", "1 c. all-purpose flour", "1 Tbsp. vanilla extract", "2 c. mini-marshmallows", "1 1/2 c. semi-sweet chocolate chips", "1 1/2 c. chopped nuts (optional)"]
["Preheat oven to 300\u00b0.", "Do not attempt to bake at a higher temperature or the brownies will burn. Generously grease and flour a 13 x 9-inch baking pan. Combine chocolate and butter in a medium saucepan, over low heat, stirring constantly until the chocolate is nearly melted. Remove from heat and stir until smooth."]
