Making fudge with added pecans is as simple as any other fudge recipe out there, you need to bring all your ingredients together in a pan until boiling, stirring in the butter, sugars, and any other added ingredients. Then just fold the pecans into the fudge and leave to set. Fudge recipes allow for any type of nuts or toppings to be added easily once you’ve got the base layer of your fudge mixed.
