Blend oatmeal and water until completely smooth. Optional: add a pinch of salt. Let the batter rest 5–10 minutes to thicken slightly.
Lightly oil a pan over low heat. Spread the batter thinly into a round shape. If it's too thick, it might turn out like a pancake and won't puff.
Cook on low heat for 4–5 minutes until the surface looks set and dry. Flip, then increase to medium-high heat.
Gently press the bread with a spatula while cooking. Flip and press a few times until it puffs up and the inside is fully cooked. Don't rush this step — the puffing happens with heat + pressure.
