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 until a thick, cohesive dough forms. The mixture should hold together when pressed.
03 - Fold in chocolate chips and nuts if using. Distribute evenly throughout the dough.
04 - Using your hands or a small cookie scoop, roll the mixture into 12 equal-sized balls, approximately 1 inch in diameter. Apply gentle pressure to ensure they hold their shape.
05 - Arrange the balls on a parchment-lined baking sheet and refrigerate for at least 30 minutes to firm up. This step is crucial for proper texture and easy handling.
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 serving.
