I've had many compliments on this fudge. My mom used to make it all the time when I was growing up. I always thought it was my grandmother's recipe and that's where she got it from. But a few years before my mom passed away, we were talking and eating this fudge. I made a comment about grandma making this fudge. My mom said, What?! grandma couldn't make fudge to save her life! LOL! She said this is from my friend's mother! So, I just call it mom's peanut butter fudge because she taught me how to make this and I always think of her when I even hear the words peanut butter fudge! This recipe posting is in honor and memory of you, mom!
Mix all ingredients (EXCEPT the peanut butter) over medium heat until mixture reaches soft ball stage. This takes about 7 - 7 1/2 minutes. You can use a candy thermometer to check this or you can do what my mom did. She used a small dish of cold water. She would place a very small amount(just a few drops)of the boiling mixture into the water to see if it would hold a ball shape. If it dissolved in the water as soon as it hits the water, it's not ready. If it hardens immediately upon hitting the water, it's too late. If you can push the mixture easily into a ball shape it's ready.
After you've reached soft-ball stage, add peanut butter. Stir thoroughly and until peanut butter is completely melted. Pour into buttered dish. ENJOY!!
