I just made this again recently, and quickly remembered why I had saved this recipe! Originally found it somewhere online, under the name “Alpha’s Peanut Butter Fudge”. I made a few modifications, and I believe they improved an already great recipe!
2 1/2 cup sugar
5 oz Evaporated Milk
1/2 cup of butter
1 Tbsp light corn syrup
18 oz Peanut Butter
1 tsp Vanilla
In a medium saucepan, dissolve sugar in evaporated milk. Add butter (cut in pieces, if desired) and corn syrup, and, stirring constantly, cook over low heat until butter is melted. Continue cooking, stirring frequently, to soft ball stage. (Using our candy thermometer, this was to 240ºF.)
Remove from heat and mix in peanut butter. Cool to about 120º F and mix in vanilla. Spread in suitable size pan (the larger the pan, the thinner each piece of candy will be). Fudge will still be very soft at this stage; it takes a few hours to set up.
I actually doubled this recipe (because of our large family) … sort of. I forgot to double the peanut butter, but did double everything else, and that was just fabulous. So I would recommend perhaps halving the peanut butter, or if doubling, just use one 18oz jar. Still very peanut buttery … and fantastic!
It took about four hours to cool/set, and then was ready to serve!
