Keto Peanut Butter Fudge


In pre-keto days, I made batch after batch of fudge and pralines.  Mark used to kid me and say that it wasn’t really Christmas until I had had a batch of fudge fail to set up properly.  Well, with this keto version, there’s no worries about reaching a hard-ball stage and no need to bother with a thermometer.  I don’t worry about overcooking it, I don’t worry about undercooking it, I don’t worry about it making me fat.  I am thankful for keto and for the keto-friendly sweeteners we have available now!
