What is oat flour?

Oat flour is oats ground into a powder for use in baking and other recipes. It is a simple way to turn a familiar pantry ingredient into a flour at home.

This version uses old-fashioned oats and a food processor or spice blender, so you can choose how fine to grind the flour.

Nutrition and macros by portion

The nutrition label shows one serving as written: 154 calories, 5g protein, 27g carbs, 3g fat.

The oats provide most of the carbohydrates, with a smaller amount of protein and fat. Pair a serving of the finished recipe in which you use this flour with a protein-rich food or fruit to make a more balanced plate.

Choosing the oats

Old-fashioned oats: use them as listed for a straightforward, versatile flour. Check that they are plain oats rather than flavoured or sweetened.

Getting the texture right

Fine flour: keep blending until the oats look powdery and even. Pause to check the texture so you do not stop while larger flakes remain.

Coarser flour: stop earlier if your recipe or preference calls for more texture.

Using a blender

Food processor: add the oats and blend until they reach the desired consistency. A spice blender is another option for grinding them.

Small batches: if your appliance struggles to move the oats evenly, grind less at a time and repeat until all the oats are processed.

How much to make

This recipe starts with 180 g of oats and takes about 5 minutes in total. Make only what you need, or grind the batch and keep the remainder stored airtight.

Ways to use it

Baking: use oat flour in recipes that call for it, such as pancakes or biscuits. Follow the recipe’s guidance, as oat flour does not behave exactly like wheat flour.

Serving ideas: use it in a dish that already calls for oat flour rather than substituting it without checking the recipe.

Recipe notes & tips

• Make sure the food processor or spice blender is clean and completely dry before adding the oats.
• Blend in short bursts if you want more control over the final texture.
• Pause and check for any larger flakes before deciding the flour is smooth enough.
• Grind a smaller amount at a time if the oats are not moving around the appliance evenly.
• Measure the flour after grinding when following a recipe that specifies a quantity of oat flour.

Variations

• Coarse grind: stop blending sooner for a more textured flour.
• Fine grind: continue blending until the oats form a uniform powder.
• Spice blender: use it instead of a food processor to grind the oats.
• Small batches: divide the oats into smaller portions if that suits your appliance.

Common mistakes to avoid

• Stopping too soon: check for visible flakes and blend again if you want a smooth flour.
• Overfilling the appliance: grind the oats in smaller batches so they can move freely.
• Using damp equipment: dry the blender or processor thoroughly before adding the oats.
• Assuming every grind is identical: check the texture and stop when it suits the recipe you are making.

How to store

Keep homemade oat flour in an airtight container in a cool, dry cupboard and use it within a few weeks for the best quality. Discard it if it develops an off smell or shows signs of moisture.
