Expert Tips
Rolled oats are the least dense ingredient in our database at 0.381 g/ml - they take up a lot of volume for their weight.
Do not substitute instant oats for rolled oats in baking - they absorb liquid faster and can make textures gummy.
For oat flour, pulse rolled oats in a food processor until finely ground. 1 cup rolled oats makes about 3/4 cup oat flour.
