My sister, Marilyn, is a gourmet-type cook and she possesses a vast recipe and cookbook collection. She emailed this recipe for my youngest daughter to make on her own. It really is foolproof.

1/2 pound margarine, melted
3/4 cup peanut butter
4 cups powdered sugar (1 pound)
3 large rounded tablespoons cocoa
1 teaspoon vanilla

Mix all ingredients together, beating by hand until smooth. Lightly butter a
9-inch square pan and line with waxed paper. Smooth fudge in pan.
Refrigerate till set (about 1/2 hour). Remove from pan and cut into 1-inch
pieces.

* If you refrigerate longer, let it sit out for a while before you cut it or
it will crumble when cutting.
