Pulse the oats (optional): If you prefer a smoother, dough-like texture, pulse the rolled oats in a food processor for 10–15 seconds to create a coarse flour. If you like more chew, leave them whole.
Mix the dry ingredients: In a medium bowl, whisk 1 1/2 cups rolled oats, 1/2 cup protein powder, and a pinch of salt.
If using ground flax or chia, whisk those in now (1–2 tablespoons).
Stir the wet ingredients: In a separate bowl, stir together 1/2 cup almond butter, 1/4 cup maple syrup or honey, 1 teaspoon vanilla extract, and 2–3 tablespoons milk. Start with 2 tablespoons milk; you can add more if needed.
Combine and adjust: Pour wet ingredients over the dry. Stir with a sturdy spoon or spatula until a thick dough forms.
If the mixture is too dry or crumbly, add milk 1 teaspoon at a time. If it’s too sticky, sprinkle in a little more oats or protein powder.
Fold in chocolate chips: Add 1/3–1/2 cup mini chocolate chips and fold until evenly distributed.
Roll into bites: Scoop about 1 tablespoon of dough and roll between your palms to form balls. You should get roughly 16–20 bites, depending on size.
Chill to set: Place the bites on a parchment-lined plate or tray.
Chill in the fridge for at least 20–30 minutes to firm up.
Enjoy or store: Once set, transfer to an airtight container. Keep chilled for best texture.
