Hi Sue :-) I found these two recipes on the internet. I have not tried them. I hope this is what you are looking for. Let me know if either of these works for you.

Peanut Butter Fudge

2 cups brown sugar
1 cup evaporated milk
1/4 to 1/2 cup peanut butter
1 teaspoon butter
vanilla
1/2 cup chopped walnuts or pecans, optional

Put all ingredients into a saucepan. Bring to a boil and continue to boil gently until a little dab added to cold water forms a soft ball. About 238° on a candy thermometer. Add peanut butter, butter, and vanilla; beat until the mixture begins to thicken. Add nuts, if using. Spread in a buttered loaf pan; chill until fully set and cut into squares.


Favorite Peanut Butter Fudge

2 cups sugar (half brown sugar if desired)
1/2 cup evaporated milk
2 tablespoons light corn syrup
1/4 teaspoon salt
1 teaspoon vanilla
1/2 cup peanut butter
1/2 to 1 cup chopped nuts, optional

Mix sugar, salt, syrup and milk in pan. Bring to boil slowly.

Cook until small amount forms soft ball in cold water, about 234 degrees on a candy thermometer. Remove from heat, add peanut butter and vanilla. Do not stir. Cool to lukewarm then beat just until creamy, losing gloss and beginning to hold shape. Stir in nuts if used. Pour into a buttered loaf pan or 8- x 8-inch pan and cool. Cut in small squares.
