1Line a 9-in. square pan with foil. Grease the foil with 1 teaspoon butter; set aside. In a heavy saucepan, melt the Tootsie Rolls, peanut butter and remaining butter over low heat, stirring constantly. Gradually stir in the confectioners' sugar, milk and vanilla (mixture will be very thick). Fold in pecans.
It may be so thick and hard to work with you think you did somehting wrong but don't worry. It is supposed to be that way. I do not use foil when I use aluminun pans.
2Spread into prepared pan. Using a sharp knife, score the surface into 1-in. squares. Press a M&M's candy into the center of each square. Cool. Using foil, remove fudge from pan; cut into squares. Store in an airtight container. Yield: about 2 pounds.
