01 - In a large mixing bowl, combine the oats, protein powder, chia seeds, cinnamon, nutmeg, and salt. Mix thoroughly to ensure even distribution of spices.
02 - Add the pumpkin puree, almond butter, maple syrup, and vanilla extract to the dry ingredients. Stir vigorously until a thick, cohesive dough forms throughout the mixture.
03 - Fold in chocolate chips and nuts if desired. Distribute evenly throughout the dough.
04 - Using your hands or a small cookie scoop, roll the mixture into 12 evenly sized balls, approximately 1 tablespoon each. Apply gentle pressure to ensure they hold their shape.
05 - Arrange the balls on a parchment-lined baking sheet. Refrigerate for at least 30 minutes to firm up before serving or storing.
06 - Transfer to an airtight container and store in the refrigerator for up to one week, or freeze for up to 3 months. Thaw frozen balls in the refrigerator before eating.
