Pinto Bean Fudge

I know, I know. It doesn't sound great. But it is a creamy, delicious fudge that never has a grainy texture. It tastes like chocolate, not beans! Check out the other options for utilizing dry beans here.
1 cup cooked pinto beans, drained
1 TB vanilla extract
6 TB unsweetened baking chocolate
6 TB butter
2 pounds powdered confectioner sugar

Puree 1 cup of soft, cooked pinto beans with a dash of milk to reach the consistency of mashed potatoes. Make sure they are smooth. Add 1 TB of vanilla to the bean mixture.

In a double boiler, melt
6 TB unsweetened baking chocolate and 6 TB of butter.

Pour the hot chocolate mixture into the beans and stir until slightly thickened.

Work in 2 pounds of powdered confectioner sugar.
Knead the mixture until smooth and spread into a 9x13 buttered baking dish. Refrigerate.

Knead mixture until smooth texture is achieved.

Spread new fudge into a buttered dish and chill until set.
It can then be cut into bite-sized pieces.
Set into paper candy cups to serve.
