Ingredients

Vegetable-oil cooking spray 

2 cups sugar 

1 teaspoon salt 

6 tablespoons unsalted butter 

1 cup heavy cream 

3 1/2 cups mini marshmallows 

3 cups semisweet chocolate chips 

1 teaspoon pure vanilla extract 

1/2 cup crushed peppermint candies 

Preparation

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.
