Roast the pecans on the stovetop until fragrant, then set aside.
In a skillet, melt most of the butter over medium heat.
Add powdered sweetener and heavy cream to the pan, stirring frequently.
Add pecans and cook until caramel color appears.
Remove pan from heat and stir in the remaining butter and vanilla extract.
Scoop the mixture onto a baking sheet lined with parchment paper using a tablespoon.
Chill in the fridge for about an hour or until set.
Enjoy!
