Chocolate Potato Fudge

2 medium potatoes (about 10 ounce total),
    peeled and cut up
1 to 2 tablespoons milk
1 (6 ounce) package semisweet chocolate chips
1 cup peanut butter
1 teaspoon vanilla extract
3 cups confectioners' sugar
1 cup finely chopped peanuts

In a large saucepan cook potatoes until very tender. Drain and mash with enough milk to make fluffy; mashed potatoes should measure 2/3 cups.

In a heavy 3-quart saucepan, heat chocolate chips over low heat until melted, stirring constantly. Remove from heat, stir in mashed potatoes, peanut butter and vanilla extract. Stir in confectioners' sugar. (If necessary, work in last 1/2 cup of confectioners' sugar with your hands.) Stir in half the peanuts. Turn the mixture into a 9-inch square baking pan. Press down evenly. Sprinkle with remaining peanuts and press down into candy. Cover, and chill until firm.

Cut into squares.

Makes about 2 1/4 pounds creamy fudge.
