1 (16 oz.) box of powdered sugar, sifted
1 stick butter (can substitute 1 Tbsp. Black Walnut Oil for 1 Tbsp. butter to enhance Black Walnut flavor)
1/4 cup milk
1/2 cup cocoa
1 tsp. vanilla
1 cup Hammons Black Walnuts (plus a few extra for the top)
Line a 9-inch plate or pie pan with aluminum foil and butter the foil.
In a 2-quart microwave safe bowl, put sugar, cocoa, butter and milk (do not stir). Place in your microwave for 2 minutes until the butter is melted. Remove and immediately add vanilla and black walnuts stirring quickly until well combined. Pour onto buttered dish, smoothing with a spatula if necessary (press additional black walnuts on top now, if desired).
Place the dish in the freezer for 10 to 15 minutes to allow fudge to set. Tip the fudge from the plate and peel off the foil. Cut into pieces with a warm knife.
