What is oat flour?

Oat flour is a whole-grain flour made from rolled oats that is high in fibre and rich in nutrients. It has a mild nutty taste and is slightly more grainy than all-purpose flour.

Oat flour can be purchased at most grocery stores or easily made at home. It’s a great and healthy alternative to using wheat flour in baked goods and pancakes and is also gluten-free if it’s made with gluten-free certified rolled oats.

These Oat Flour Banana Muffins are similar to oatmeal muffins, but have a finer texture.

Expert tips for making oat flour muffins

  • Use overripe spotty bananas. You know those really old bananas sitting on the counter that you’re debating if you should throw out? Those are the best bananas to use in muffins! They will give the best taste and add natural sweetness.
  • Don’t overmix the batter. Overmixing muffin batter will lead to dense and tough muffins.

  • Add any mix-ins you love. Chocolate chips, walnuts and dried fruit are all delicious in these muffins!
