I love experimenting with alternative flour options like almond flour, coconut flour, and oat flour! It’s an easy way to increase the nutrient density of your baked goods while exploring new ingredients.
Oat flour is a nutritious, whole-grain flour that can be used in a variety of healthy baking recipes including pancakes, brownies, cookies, and bread (homemade banana bread, anyone?). It has a mildly sweet, nutty flavor. Plus, it’s naturally gluten-free when made with certified gluten-free oats.
While you can buy oatmeal at most grocery stores, it’s super easy (and way more affordable) to make at home – it literally takes just 1-minute – let me show you how!
What is oat flour?
Oat four is simply rolled oats that are blended into fine flour! The best part? Homemade oat flour requires only one ingredient; oats!
- Rolled oats are ideal. You can use old-fashioned rolled oats or quick oats. I always look for organic oats as I love to focus on high-quality ingredients. Be sure to choose certified gluten-free oats if you want to make gluten-free oat flour.
You can also make oat flour using whole oat groats or steel-cut oats. Because they are both harder in texture than rolled oats, they will need a little extra time in the blender! If possible, I recommend using a high-speed blender since they are more powerful.
Is Oat Flour Gluten Free?
While oats are naturally gluten-free, they may come in contact with gluten-containing grains such as wheat, rye, and barley at the farm, in storage, or during transportation. This is why it’s important to choose certified gluten-free oats if you want to ensure that your oats are gluten-free.
Is Oat Flour Healthy?
Oat flour is a healthy alternative to wheat flour because it contains a variety of nutrients! naturally gluten-free. Here are some of the health benefits:
- Protein – I’m always looking for ways to increase my protein intake! And, oat flour offers 5-6 grams of plant-based protein per 1/2 cup serving (or 40 grams).
- High in fiber – Oat flour contains both soluble and insoluble fiber, which can help us to feel fuller for longer!
- Rich in vitamins and minerals – Nutrient density is important when eating a healthy diet! Oat flour contains iron, phosphorus, magnesium, and vitamin B6 (just to name a few!).
- Gluten-free: Oat flour is naturally gluten-free as long as you use gluten-free oats. This makes it a great option for people with gluten sensitivities or celiac disease.
- Affordable – The stress of eating healthy can be REAL! But oats are a simple, nutritious ingredient that is also very affordable. You can often find over 16 ounces of oats for around 3 dollars and they are even less expensive when bought in bulk.
What I love about making my own oat flour is that I always have oats in my pantry. So making healthy, homemade oat flour is never a problem! And since it’s so quick and easy to do, I rarely buy it pre-made.
How To Make Oat Flour at Home
Dare I even call this a recipe?! It’s just so easy! But hey, we all have to start somewhere. Here’s all you have to do.
- Place your rolled oats into a blender or food processor.
- Blend the oats until they are broken down. This will take about 30 seconds. At first, they will look like smaller pieces of oats. But you will know your oat flour is done when it is finely ground and looks like a fine powder.
How to Store: Transfer oat flour to a resealable, airtight container. Mason jars work really well! If you plan to make a lot of oat flour, I also really love these POP containers for storing sugar and flour.
How To Substitute for Oat Flour
Because oat flour is lighter in volume than traditional white or wheat flour it’s not a 1-to-1 swap. If you want to substitute oat flour for white or wheat flour you would need to increase the volume of flour used by about 1/3 cup of flour per cup.
For example, if a recipe calls for 1 cup of white or wheat flour, you will swap in 1 and 1/3 cups of oat flour. It may take a little trial and error – if the batter or dough seems too stiff, add a little more liquid.
