Use a large mixing bowl. Line a tray or plate with parchment for setting the bites.
Add oats, flax/chia, protein powder, salt, cinnamon, nuts/seeds, and dried fruit. Stir to distribute evenly.
In the same bowl, add nut/seed butter, honey or maple, and vanilla. Mix with a sturdy spoon or clean hands.
If the mixture crumbles, add water or milk alternative 1 tablespoon at a time. If it's too sticky, add a bit more oats.
Add mini chips or cacao nibs last so they don't melt from overmixing friction. Yes, that's a thing.
Scoop 1–1.5 tablespoons per bite and roll into balls. Lightly damp hands prevent sticking.
Let them rest at room temp for 20–30 minutes to firm up as the oats hydrate.
Transfer to an airtight container with parchment between layers.
