Pulse the oats (optional). For a softer bite, blitz the oats in a food processor for 5–10 seconds. If you like more chew, leave them whole. Your snack, your rules.
Mix the wet team. In a large bowl, stir together pumpkin puree, nut butter, maple syrup/honey, and vanilla until smooth and glossy.
Add the dry team. Stir in protein powder, oats, pumpkin pie spice, chia seeds, and salt. Use a sturdy spatula. If it's too dry and crumbly, add milk 1 tablespoon at a time. If it's too sticky, add a tablespoon of oats or protein powder.
Fold in chocolate chips. Keep a few for the tops if you want that bakery look.
Chill the dough (10–15 minutes). This firms it up and makes rolling easier. Also prevents chocolate from smearing like you finger-painted your snack.
Roll into bites. Scoop about 1 heaping tablespoon per ball (around 18–22 bites). Roll tight for better hold.
Set and serve. Refrigerate for 20 minutes to set. Eat straight from the fridge or let them warm up for ultra-soft, cookie-dough vibes.
