things people ask

• How much does a cup of oat bran weigh for muffins?
  Around 106 g spooned into the cup and leveled. Classic oat bran muffin recipes — the kind that took off when soluble fiber and cholesterol claims went mainstream — typically call for 1 to 2 cups, so you're working with 106-212 g of bran as the structural base alongside flour, eggs, and oil. Scoop straight from the bag and you'll easily add 10-15 g extra.
• Can I replace flour with oat bran cup-for-cup in bread?
  Not the whole amount. Oat bran has no gluten and absorbs more liquid than wheat flour, so swapping a full cup of flour for a full cup of bran gives you a dense, crumbly loaf. The standard move is replacing about 1/4 of the flour — roughly 30 g of bran per 120 g of flour — which adds fiber without wrecking the rise.
• Is oat bran the same as oat flour?
  No. Oat flour is whole groats milled fine, so 1 cup runs about 90-95 g and behaves like a soft flour. Oat bran is just the fibrous outer layer separated out before milling, so the same cup weighs around 106 g and has visibly larger flakes. They're not interchangeable by volume — bran is concentrated fiber, flour is starch plus fiber.
