You can find the full printable recipe, including ingredient quantities, below. But first, here are some explanations of ingredients and steps to help you make this recipe perfect every time.
- Place oats in a food processor or blender.
- Cover and pulse on low until the oats are mostly broken down.
- Use a spatula to stir the oats.
- Cover and pulse, gradually increasing the speed.
- Repeat this process until you achieve the desired texture.
To achieve a fine flour, you’ll need a high-speed blender. Other blenders will work, but you may not be able to achieve a finely-milled flour product.
Ingredients & Substitutions
You’ll need oats for this recipe, and that’s it. But the quantity does matter.
The minimum amount of oats you can use in a blender or food processor is one cup, but 2 cups will work even better.
What type of oats is best for making flour?
I find that old-fashioned or rolled oats are best for grinding oats into flour. You can also use instant oats, which have been processed a bit more, and have a finer grain.
Oat Flour Conversion
It’s good to know how much oats you’ll need for use in your recipes.
- Add 1 cup + 3 tablespoons of rolled oats to a blender to process into 1 cup of oats flour.
- If you add 2 cups of rolled oats to a blender, it will create approximately 1 3/4 cups of oatmeal flour.
- When baking with flour from oatmeal, for every 1 cup of all-purpose flour called for in a recipe, substitute 1 1/3 cups of ground oat flour. Assess your batter. If it seems too stiff, you can add a bit more liquid.
Storage Tips
Store flour from oats in an airtight container. It will keep in the pantry for up to 2 months, but it can go stale, so I prefer to refrigerate it. You can store it in the fridge or freezer for up to 6 months.
Using Oatmeal Flour in Gluten-free Baking
Is oat flour gluten-free? It’s an important question when you’re baking gluten-free. Some oats are milled on the same equipment as other grains.
Be sure to look for oats or flour from oats that are labeled gluten-free. This guarantees that the flour is free of any traces of other grains and is safe for those who are celiac or have sensitivity to gluten.
Ground oats make a great addition to most gluten-free baking recipes because they add a whole-grain nutritional boost without the strong taste of some gluten-free flours.
Additionally, it can help with binding dough together and adds subtle sweetness to the finished product. It’s a versatile flour that has many baking uses.

Oatmeal Flour

- Repeat processing until a flour texture is achieved. This may take several minutes using a food processor.
- Blender Method: Add oats to a blender jar and pulse in short bursts until the oats are broken down into smaller bits. Use a rubber spatula to remove oat bits on the side or bottom of the jar.
