In a large mixing bowl, combine pumpkin puree, nut butter, honey, and vanilla extract. Blend until smooth and creamy.

In a separate bowl, whisk together rolled oats, protein powder, ground cinnamon, nutmeg, and salt.

Gradually add the dry mixture into the wet ingredients, stirring until a thick, sticky dough forms.

Cover the bowl with plastic wrap and refrigerate the dough for 20-30 minutes.

Once chilled, use a tablespoon to portion out the mixture and roll into balls.

Transfer the rolled balls to an airtight container and store in the refrigerator for up to a week.
