EATING MY EMPIRE
Line a 9-by-13-inch baking pan with two strips of waxed or parchment paper (one lengthwise, one crosswise) so ends overhang sides of pan; coat evenly with cooking spray. Set aside.
Put sugar, salt, butter, cream, and marshmallows in a heavy-bottomed saucepan over medium heat. Cook, stirring, until butter and marshmallows are almost melted, 5 to 6 minutes.
Bring mixture to a boil; cook, stirring occasionally, 5 minutes. Remove from heat. Add chocolate chips and vanilla; stir until chips are melted. Pour mixture into lined pan.
Let fudge cool in the pan at room temperature 3 hours. Use edges of paper to lift out fudge; place on cutting board, and remove paper. Cut out shapes with cookie cutters, and top with crushed mints.
