Black Cherry Swirl Fudge
Ingredients
1-1/2 teaspoons plus 3/4 cup butter, divided
3 cups sugar
3/4 cup heavy whipping cream
1 package (10 to 12 ounces) vanilla or white chips
1 jar (7 ounces) marshmallow creme
2 envelopes unsweetened black cherry soft drink mix
Directions
Line a 13-in. x 9-in. pan with foil and grease the foil with 1-1/2 teaspoons butter; set aside. In a heavy saucepan, combine the sugar, cream and remaining butter. Bring to a boil over medium heat, stirring constantly. Cook and stir for 4 minutes.
Remove from the heat; stir in vanilla chips and marshmallow creme. Pour 1 cup into a bowl; set aside. Stir black cherry drink mix into the remaining marshmallow mixture. Pour into prepared pan. Spoon reserved marshmallow mixture over top; cut through mixture with a knife to swirl.
Refrigerate for 1 hour or until firm. Using foil, lift fudge out of pan. Discard foil; cut into 1-in. squares. Store in an airtight container in the refrigerator. Yield: about 3 pounds.
