Working quickly, spoon approximately 1-2 tablespoons of the praline topping over the cookies. Immediately sprinkle praline topping with remaining chopped pecans. Let praline topping harden before serving.
Cookies can be stored using the FoodSaver® system for 3-6 weeks in the pantry or for 1-3 years in the freezer.
If praline topping begins to harden before you are finished frosting the cookies, simply reheat with ½ - 1 tablespoons heavy cream over low heat until frosting is pourable again.
