1. In a nonstick saucepan, melt butter over medium-low heat.

2. Add sweetened condensed milk, pumpkin purée, pumpkin pie spice, cinnamon, and salt.

3. Cook, stirring constantly, until the mixture thickens and pulls away from the sides of the pan, about 12–15 minutes.

4. Remove from heat and stir in vanilla extract.

5. Transfer the mixture to a greased plate or dish. Let cool to room temperature, then chill in the fridge for at least 1 hour.

6. Once chilled, scoop and roll into 1-inch balls.

7. Roll each ball in cinnamon sugar until fully coated.

8. Serve immediately or refrigerate in an airtight container for up to 5 days.
