Line baking sheet with parchment paper and set aside.
Place large saucepan on stovetop over medium-high heat. Add 1 tablespoon refined coconut oil and let oil melt completely, swirling and tilting saucepan occasionally to distribute oil across surface.
Once oil has melted, add 6 tablespoons 100% pure pumpkin purée, ¼ cup pure maple syrup, and 2 tablespoons creamy peanut butter. Stir ingredients together until peanut butter has melted and ingredients are fully combined.
Remove saucepan from heat. Add ½ tablespoon pure vanilla extract, ¼ teaspoon ground cinnamon, 1 pinch salt, and 1 cup rolled oats to pumpkin mixture and stir well until ingredients are fully incorporated.
Optional: Add ½ cup chocolate chips to mixture and gently fold in until just incorporated.
Let mixture cool enough to handle, then use 1-inch cookie scoop with release handle to portion cookie batter onto prepared baking sheet, leaving space between each scoop to allow for spreading.
Once entire pumpkin mixture has been portioned into individual cookies, place filled baking sheet in refrigerator, ensuring baking sheet sits flat. Refrigerate cookies 1 hour minimum.
When ready to serve cookies, remove baking sheet from refrigerator. Carefully peel cookies off of parchment paper and transfer to serving plate or airtight container. Serve cookies chilled or at room temperature.
