01 - In a large mixing bowl, combine oats, protein powder, cinnamon, nutmeg, ginger, and salt. Mix thoroughly to distribute spices evenly.
02 - In a separate medium bowl, stir together pumpkin puree, nut butter, maple syrup, and vanilla extract until completely smooth and creamy.
03 - Pour the wet mixture into the dry ingredients. Stir vigorously until well combined and a thick, cohesive dough forms. The mixture should hold together when pressed.
04 - Gently fold in chocolate chips and chopped nuts if using, distributing them evenly throughout the dough.
05 - Scoop heaping tablespoons of the mixture and roll into smooth balls using your hands, approximately 1 inch in diameter. Apply gentle pressure to ensure they hold their shape.
06 - Place the formed bites on a parchment-lined tray or plate, ensuring they are not touching each other.
07 - Refrigerate for at least 30 minutes before serving to allow the bites to firm up and flavors to meld together.
08 - Store in an airtight container in the refrigerator for up to 1 week. For longer storage, freeze in a freezer-safe container for up to 3 months.
