Start by lining a baking sheet with parchment paper.

In a small saucepan, combine the pumpkin puree, coconut oil, brown sugar, and peanut butter over medium-high heat. Stir continuously until the mixture melts and becomes uniform, about 3-5 minutes.

Bring the mixture to a gentle simmer for 60-90 seconds while stirring steadily to prevent sticking.

In a large mixing bowl, combine the oats, salt, pumpkin pie spice, and vanilla extract. Stir well to distribute the flavors.

Pour the cooled pumpkin mixture over the dry ingredients and fold everything together until combined.

Drop portions of the mixture onto the prepared baking sheet, aiming for small, evenly sized rounds.

Allow the cookies to cool and set at room temperature for at least 30 minutes.
