Mix the Dry Ingredients In a large bowl, whisk oat flour, protein powder, baking powder, cinnamon, and salt until well combined.
Blend the Wet Ingredients In another bowl, beat the eggs lightly. Add Greek yogurt, milk, vanilla, and sweetener. Stir until smooth.
Combine and Adjust Pour the wet mixture into the dry ingredients. Gently fold until just combined — a few lumps are okay.If the batter is too thick (it should look like cake batter), add a splash more milk. Too thin? Sprinkle in a little oat flour.
Let the Batter Rest (Important!) Allow it to sit for 5 minutes. This hydrates the oats and lets the baking powder activate — your secret to true fluff.
Heat & Cook Preheat a nonstick skillet or griddle to medium-low. Grease lightly. Scoop ¼ cup of batter per pancake.When bubbles form on top and the edges look set (about 2–3 minutes), flip and cook another 1–2 minutes.
Keep Warm & Serve Place finished pancakes on a baking sheet in a 200 °F oven while you cook the rest.Stack, drizzle, top, and devour.
