Pinto Bean Fudge

Pinto Bean Fudge
1 C cooked pinto beans, mashed
1/4 to 1/2 C milk
1 Tbsp vanilla
6 oz unsweetened chocolate
6 Tbsp butter
2 lbs powdered sugar

Add milk to mashed pinto beans until the consistency is that of mashed potatoes. Add vanilla.  Melt chocolate and butter in a double boiler and pour melted mixture into bean mixture and stir until slightly thickened.  Work in powdered sugar.  Knead with hands.  Spread into slightly buttered pan.  Refrigerate.  Makes 3 1/2 lbs.  Keep refrigerated.

NOTE:  Unfortunately I can't give credit to the person who gave me this recipe, because I have had it for over 25 years and don't remember who I got it from.
NOTE: I tried making this with mashed white beans and it tasted fine.  The only problem was that the skins didn't mash, so it made the texture different.  If you added walnuts then I don't think the skins would be noticed.
