In a food processor, combine pumpkin puree, peanut butter, maple syrup, toasted pecans, pumpkin pie spice, flaxseed meal, chia seeds, sea salt, and old-fashioned rolled oats. Pulse until the mixture forms a thick, cohesive paste.

Using a medium cookie scoop, portion out the mixture and roll into bite-sized balls, aiming for about 15 bites total.

Place the rolled bites on a parchment-lined baking sheet and freeze for 30 minutes.

In a microwave-safe bowl, combine chocolate chips and coconut oil. Heat in 30-second intervals until smooth and melted.

Drizzle the melted chocolate over the energy bites once they are firm, then sprinkle lightly with cinnamon.

Return bites to freezer for 10 minutes to set the chocolate.

Transfer the energy bites to an airtight container for storage, keeping in the freezer for up to 3 months.
