4 cups sugar
1 cup whole milk (no substitutes)
1 teaspoon vanilla
25 large marshmallows, cut in half
1 cup real butter (no substitutes)
13 ounces semi-sweet chocolate chips
2 ounces unsweetened chocolate
13 ounces milk chocolate chips
1 cup chopped pecans (optional)
Mix sugar, milk, butter and vanilla. Bring to a boil for 2 minutes.
Turn off heat, add marshmallows and stir until completely melted. Add chocolates one type at a time and beat until melted. Spread into a large, deep and buttered cookie sheet or a 12-inch by 16-inch by 1-inch cake pan.
Note: Since the chocolate chip packages are now only 11.5 ounces, add extra milk chocolate chips from an additional package of chips. The recipe makes about five pounds of fudge.
