If you’ve ever bought oat flour at the store, you know it can be pricey compared to a bag of oats. The good news? Homemade oat flour is one of the easiest, cheapest, and most versatile flours you can make at home.
Whether you’re gluten-free, off-grid, meal prepping, or just love baking, this pantry staple will save you money while keeping your kitchen stocked with a nutritious flour alternative.

What is Oat Flour?
Oat flour is simply oats ground into a fine powder. It has a mild, nutty flavor and works beautifully in:
- Muffins, pancakes, and waffles
- Cookies and breads
- Energy bites and protein bars
- Smoothies for added creaminess
- Gluten-free baking mixes
It’s naturally high in fiber, protein, and nutrients, making it a great substitute for white flour in many recipes.
How to Make Homemade Oat Flour
Ingredients:
- 1 cup Old Fashioned Oats (certified gluten-free if needed)
Instructions:
- Place oats in a blender, food processor, or high-powered coffee grinder.
- Blend until the oats become a fine, flour-like powder.
- Sift for a super-smooth flour or leave slightly coarse for rustic recipes.
- Store in an airtight container in your pantry for up to 3 months (or in the freezer for 6–8 months).
That’s it! In under 2 minutes, you’ll have DIY oat flour ready for all your baking needs.

Not required, but sifting creates a smoother flour for cakes and pastries.
