1. In a medium-sized mixing bowl, combine the rolled oats, pumpkin pie spice, and a pinch of salt. Stir them together well with a spoon or spatula to ensure the spices are evenly distributed.

2. Pour in the pumpkin puree, nut butter, maple syrup (or honey), and vanilla extract into the bowl with the dry ingredients.

3. Using a sturdy spoon or your hands, mix all the ingredients until a thick, uniform dough forms. It should be well combined and sticky enough to hold together when pressed. If using, fold in any optional mini chocolate chips or chopped nuts at this stage.

4. Cover the bowl with plastic wrap and place it in the refrigerator for at least 30 minutes. This chilling step is important as it helps the mixture firm up, making it much easier to roll into balls.

5. Once chilled, remove the mixture from the refrigerator. Scoop out small portions (about 1 tablespoon each) and roll them between your palms to form compact, bite-sized balls.

6. If desired, roll the formed balls in shredded coconut or a sprinkle of extra pumpkin pie spice for an added layer of flavor and texture.

7. Place the finished energy balls in an airtight container. Keep them refrigerated until you’re ready to enjoy them.
