1/2 pound Kraft Velveeta, sliced
2 sticks butter (1 cup)
1 teaspoon vanilla
1 cup chopped nuts
2 16 oz. boxes powdered sugar
1/2 cup cocoa powder
Spray a 9"square pan with cooking spray. In a saucepan over medium heat, melt butter and cheese together;stirring constantly until smooth. Remove from heat and stir in vanilla and nuts. Sift together sugar and cocoa in a large bowl. Pour cheese mixture into sugar mixture and stir until completely mixed; it will be very stiff. Press candy into prepared pan. Pat top of candy with a paper towel to remove any excess oil. Chill until firm.
For peanut butter fudge--add 1 cup peanut butter to the cheese mixture afterbutter and cheese have been melted together and omit the cocoa.
