How to Measure Oat Flour Accurately

To measure oat flour accurately, use the spoon-and-level method: loosen it, spoon it into a dry measuring cup, and level the top. Scooping the cup straight into the bag packs oat flour down and adds weight.

  1. 1

    Loosen the powder

    Stir or whisk the oat flour in its container to break up clumps and settled layers.

  2. 2

    Spoon it into a dry measuring cup

    Spoon it in lightly until the cup overflows. Do not tap, shake, or press the cup.

  3. 3

    Level the top

    Sweep a straight edge, such as the back of a knife, across the rim to remove the excess.

  4. 4

    Weigh it for an exact amount

    Set a bowl on a kitchen scale, press tare, and add oat flour until the scale shows the gram amount in the recipe.
