In a medium-sized pot, combine the brown sugar, salted butter, and evaporated milk. Bring the mixture to a boil over low medium heat while whisking constantly.
Once the mixture has come to a boil, allow it to cook for 3-4 minutes while whisking. The mixture should become thick and have a creamy consistency.The perfect consistency for this sauce is when it coats the back of a spoon without immediately running off. It should be sticky, thick, yet pliable.
Once the mixture coats the back of the spoon, lower the heat. Add your chopped nuts to the hot sauce, give the ingredients a whisk, and remove them from the heat.Allow the pecan praline sauce to cool completely before adding it on top of your cooled cheesecake. Alternatively, you can store this sauce in a clean mason jar.
