1:1 substitution for cake flourOat flour is gluten-free and contains soluble fibers that can thicken liquids, which can benefit custards by adding body. However, it lacks gluten, so the custard may be less elastic and slightly denser.
Use finely ground oat flour and sift it well to avoid graininess. Be aware that oat flour may cause the custard to appear less translucent.
The final product will have a slightly different flavor and texture, with a creamier but less smooth mouthfeel compared to cake flour.
