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 and seeds.
02 - Add the pumpkin puree, almond butter, maple syrup, and vanilla extract to the dry ingredients. Stir vigorously until a thick, cohesive dough forms and all dry ingredients are fully incorporated.
03 - Fold in chocolate chips and nuts if desired, distributing them evenly throughout the dough.
04 - Using your hands or a small cookie scoop, roll the mixture into 12 evenly sized balls, applying gentle pressure to ensure they hold their shape.
05 - Arrange the balls on a parchment-lined tray and refrigerate for at least 30 minutes to firm up before serving or storing.
06 - Store in an airtight container in the refrigerator for up to one week, or freeze for up to 3 months. Thaw frozen portions in the refrigerator before eating.
