In a saucepan over medium heat combine the sugar, butter, and heavy cream. Heat to the softball stage which is about 235 degrees℉, stirring constantly. Then stir for about 3 minutes while boiling.
Remove from heat and stir in the marshmallow cream and white chips. Stir until the white chips are well blended and melted.
Reserve 1 cup of the mixture and set aside in another bowl.
Add orange extract and food coloring to the remaining mixture left in the saucepan. Stir well and pour into the greased 9x13 inch pan.
Then pour or drizzle the reserved white mixture that you set aside over the orange fudge. With a knife swirl it into the fudge back and forth.
Refrigerate until set, about 2 hours. Then cut into squares and serve.
Notes
Be sure to grease your 9 x 13 inch pan. If you don’t the fudge may stick to the pan, and the presentation won’t look as good. You could also use parchment or wax paper, and place it in the bottom of the pan.
