Super Easy Peanut Butter Fudge

"This recipe is very simple, but if you do not know how to make candy then please follow instructions precisely. I have altered the instructions after a few reviews that it was crumbly. This is not the recipes fault, it is inexperience. Proper candy making is about temperatures. 4 minutes of boiling (from the time the first small bubbles form) bring this candy up to proper fudge/softball temperature as long as you are cooking over medium heat. When in doubt, use a thermometer...."
