Oat Flour

Find out how to bake with Oat flour and make delicious recipes like breads, muffins, and cookies.

Oat flour is fun to cook with and easy to make at home. It brings a creamy taste and unique health benefits to any recipe. Rich in soluble fiber, this flour makes for noticeably moist breads, scones, and muffins. Oats are also virtually gluten-free, meaning people with gluten allergies (Celiac's) can often tolerate foods made with this type of flour.

It can be bought or made at home simply by putting uncooked oatmeal in the blender until it becomes the consistency of flour. Oat groats (whole oats) can be used to make flour, as well, but you will need a coffee or wheat grinder to grind it fine enough.

Once you have your oat flour you can try one of our featured recipes or better yet, adapt a recipe of your own and share it with the rest of us.. But before you do, there are certain things you should know:

  • Oat flour contains little-to-no gluten. So when cooking yeast breads you can only substitute about 1/3 of the recipe's flour with flour from oats. Any more than this and your bread won't rise or even worse, you'll bake a brick.

  • When substituting this type of flour in a recipe, add a touch more water because oats soak up a lot of water.

  • Never make flour out of Instant Oats. They are precooked, so cooking them again will turn them into mush. Always use standard oats. They are not cooked (just rolled thicker or thinner).

    Banana Oat Muffins

    Ingredients (Serves 12)

    3/4 cup Old Fashioned Oatmeal, uncooked
    1/2 cup wheat flour
    1/2 cup oat Flour
    To make your own flour from oats, place 3/4 cups quick or old-fashioned oats, uncooked, in blender or food processor. Cover and blend 60 seconds. Makes 1/2 cup flour.
    1/4 cup white Flour
    1/4 cup bran
    1 1/2 teaspoon baking powder
    1/4 teaspoon baking soda
    1/8 teaspoon Salt
    1/4 cup flaxseed, ground (optional)
    1/4 cup sunflower seeds
    1/4 cup pumpkin seeds
    1/2 cup walnuts, chopped
    2 large eggs
    3 large bananas, mashed (see substitutes)
    1/3 cup honey (see substitutes)
    2/3 cup low-fat plain yogurt (see substitutes
    1 teaspoon vanilla


    Preheat oven to 350 degrees (F) and line muffin tin with paper liners.

    In a large bowl, mix together dry ingredients.

    In a separate bowl, beat eggs. Mix in mashed bananas, honey, yogurt, and vanilla until well blended.

    Stir wet ingredients into the dry ingredients just enough to moisten the dry ingredients.

    Spoon batter into the prepared muffin tins and bake for 15 to 20 minutes, or until a toothpick inserted into the center of a muffin comes out clean.

    Cool about 15 minutes.

    These delicious and healthy muffins can be prepared ahead of time and frozen. Then for a quick breakfast or snack, just reheat them in the microwave for a few seconds.

    Substitutions and Additions

    Substitute 2 cups of diced Granny Smith apples for the bananas. First mix the diced apples with 1 teaspoon cinnamon and 1/4 teaspoon nutmeg. Then mix them into the dry ingredients before adding the wet ingredients.

    1 1/3 cups sugar plus 1/3 cup water can be substituted for the honey.

    Buttermilk can be substituted for the yogurt. Don't have buttermilk? Just add 1 tablespoon of lemon juice to milk and let stand 5-10 minutes.

    oat flour cookies

    Easy Cut-Out Cookies

    Ingredients (Serves 60)

    1 1/2 cups confectioners' sugar
    1 cup butter
    1 egg
    1 teaspoon vanilla extract
    2 1/4 cups all-purpose flour
    1 1/4 cup oat flour
    To make your own flour from oats, place 1 2/3 cups quick or old-fashioned oats, uncooked, in blender or food processor. Cover and blend 60 seconds. Makes 1 1/4 cup flour.
    1 teaspoon baking soda


    In a large bowl, add the confectioners' sugar and butter. Beat with an electric mixer set on medium until creamy. Beat in the egg and vanilla.

    In a separate bowl, combine all the flours and baking soda. Then stir dry-mix into the creamed mixture. Cover the dough, and chill for 30 minutes to 1 hour.

    On a lightly floured surface, roll the dough out to 1/8 inch thickness (if the dough is too thick you will lose some of your shapes). Using cookie cutters, cut dough into desired shapes. Place cookies 2 inches apart onto an ungreased cookie sheet.

    Preheat the oven to 375 degrees F (190 degrees C). Bake for 7 to 8 minutes and watch carefully to make sure the cookies don't over-brown or burn. Remove from baking sheets and cool on wire racks. Eat plain or frost with your favorite cookie frosting (these cookies only need a tiny amount of frosting).
