Penny, I found this recipe on the Kitchenlink under Candy and Chocolate Recipes. It sounds real good. Check it out, there are many, many more fudge recipes there.

PEANUT BUTTER FUDGE

1 (12 oz.) pkg. peanut butter flavored chips
1 (14 oz.) can sweetened condensed milk
1 c. miniature marshmallows
1 c. chopped peanuts

In heavy saucepan, over low heat, melt chips with sweetened condensed milk.
Add marshmallows; stir until melted. Stir peanuts into mixture. Spread into
wax paper-lined 8 or 9-inch square pan. Chill 2 hours or until firm. Turn
fudge onto cutting board; peel off paper and cut into squares.

Hope this helps.
