Begin by gathering a large mixing bowl. Add the rolled oats, pumpkin puree, almond butter, honey (or maple syrup), and vanilla extract to the bowl.
Sprinkle in the pumpkin pie spice, ground cinnamon, and a pinch of sea salt. Use a wooden spoon or spatula to mix thoroughly until all ingredients are well incorporated, resulting in a sticky batter-like consistency.
Gently fold in the chopped pecans or walnuts along with the dark chocolate chips or dried cranberries, making sure they are evenly distributed throughout the mixture.
With your hands, pinch off portions of the mixture and roll them into balls, approximately 1 inch in diameter. Ensure a compact shape by rolling them in your palms.
Arrange the formed energy bites on a baking sheet lined with parchment paper, allowing space between each ball.
Transfer the baking sheet to the refrigerator and chill for at least 30 minutes to allow the bites to set and firm up.
Notes
For an appealing display, serve the energy bites in a decorative jar or a vibrant small bowl. Store any leftovers in the refrigerator.
