Oat Powder Recipe

Making your own oat powder at home couldn’t be easier! Here’s a simple step-by-step method:


  • Rolled oats or steel-cut oats
  • Blender or food processor


  • Add oats to a high-speed blender or food processor. Use roughly 2 cups oats to start.
  • Blend the oats on high speed for 20-30 seconds, stopping to stir or shake periodically. They should grind down into a fine, flour-like powder.
  • Keep blending in short 5-second bursts and shaking the blender to get the oats as fine as possible. It should feel smooth like regular flour when done.
  • For storage, transfer the freshly made oat powder to an airtight container. Enjoy in baked goods or store for later use.


It only takes a minute or two to go from whole oats to fine fresh oat powder. Be sure to use a powerful high-speed blender for best results.

Let’s look at some specific tips for working with different oat varieties when making powder:

Rolled oats: These oats have been steamed and flattened, making them easy to grind into powder. They produce oat powder with a smoother consistency.

Steel-cut oats: Since steel-cut oats are less processed and dense, they take longer to grind down. But the end result is worth it – steel-cut oat powder has a delightful hearty texture.

No matter which you use, you can’t go wrong crafting homemade oat powder!

How to Use & Store Oat Powder in Baking

Now comes the fun part: putting your fresh oat powder to use in delicious baked treats! Here are some tips:

  • Start by using oat powder to replace 25% of the all-purpose or white flour called for in a recipe. This will allow you to keep the texture while adding nutrition.
  • Cookies, muffins, quick breads like banana and zucchini, and even pancakes are all great places to use oat powder.
  • To replace all the normal flour in a recipe, use a blend of roughly half oat powder and half almond flour or other gluten-free flour instead.
  • Allow thick batters and doughs to rest for 5-10 minutes after mixing to let the oat powder fully hydrate for best results.
  • Get creative and come up with your own recipes highlighting oat powder! It brings great flavor and texture to bars, donuts, breads, scones, and more.

Here’s a handy table outlining substitution ratios when using oat powder in baking:

Like any freshly milled flour, proper storage is key to preserving the taste and shelf life of your homemade oat powder. Here are some tips:

  • Store oat powder in an airtight container in a cool, dark place like your pantry for everyday use. A large mason jar works great.
  • To maximize freshness, keep oat powder in the refrigerator for up to 4 months.
  • For long term storage, put oat powder in a freezer bag or freezer-safe container. It will keep for up to 1 year in the freezer.
  • No matter where you keep it, make sure oat powder stays in an airtight container to prevent moisture exposure.

Taking a little time to store your oat powder properly ensures it stays fresh so you can enjoy using it for months to come!

My name is Sarah and I'm a baker who loves trying out new recipes and flavor combinations. I decided to challenge myself to use a new spice or ingredient powder in my baking each week for a year. Some successes were the cardamom sugar cookies, vivid turmeric cake, and beetroot chocolate cupcakes. Failures included the bitter neem brownies and overwhelmingly hot ghost pepper snickerdoodles. Through this experience I've discovered amazing additions to spice up desserts while learning how to balance strong flavors. Follow my journey as I push the boundaries of baking with unique powders!
