In a small saucepan over medium heat, combine the peaches, water, sweeteners, and cinnamon. Bring to a simmer and cook until the peaches are tender and soft. Remove from heat and set aside.
Pecan Crumble
In a small saucepan over medium, combine the pecans, butter, sweetener, and salt. Cook, stirring frequently, until the pecans are lightly toasted, 4 to 5 minutes. Remove from heat and let cool completely.
Cheesecake Filling
In a large bowl, beat the cream cheese until very smooth. Add the sweetener and vanilla extract and beat until well combined.
In another bowl, beat the whipping cream until it holds stiff peaks. Fold the cream into the cream cheese mixture until no streaks remain.
To assemble
Break up the pecan mixture with your fingers into small pieces. Add about 1 tablespoon of the pecan crumble to the bottom of 6 small dessert glasses (about 1/2 cup capacity).
Spoon or pipe the cheesecake filling into the glasses. Divide the peach sauce overtop the cheesecake.
Sprinkle with additional pecan crumble. Serve immediately or chill until ready to serve.
Notes
Storage information: Store the cheesecake cups in the fridge for up to 3 days.
