In a bowl, whisk together the oat flour, protein powder, baking powder, baking soda, and salt. No need to overthink—just remove the clumps.
In a separate bowl, mix the dairy-free milk, maple syrup, chia or flax (if using), and vanilla extract. Stir until well combined.
Pour the wet into the dry and mix until just combined. If the batter looks thick, add a splash more milk; if it’s too runny, add a little more oat flour. You’re aiming for a pourable, dollop-friendly consistency.
Let the batter rest for 5 minutes. This helps the chia/flax absorb liquid and the bubbles settle in. Patience, young pancake chef.
Heat a nonstick pan over medium heat and lightly grease. Pour 1/4 cup batter per pancake and cook until bubbles form on top and edges look set, about 2–3 minutes.
Flip carefully and cook another 1–2 minutes until golden. Transfer to a plate and keep warm with a loose cover if stacking.
