The Health Benefits of Oat Flour
Oat flour is rich in dietary fiber, particularly beta-glucan, which helps lower cholesterol levels and improve heart health. It's also packed with essential vitamins and minerals like magnesium, iron, and B, making it a nutritious choice for baking. Oat flour is a safe and delicious alternative for those following a gluten-free diet, provided it's certified gluten-free to avoid cross-contamination.
Besides its nutritional benefits, oat flour has a lower glycemic index than refined wheat flour. This means it leads to a slower rise in blood sugar levels, making it a good option for those managing diabetes or aiming to maintain steady energy levels throughout the day.
Ingredients Needed for Oat Flour Cookies
Here is a quick look at what you will need. The full measurements are in the recipe card below.

- Oat flour: Oat flour is the star ingredient in these cookies. It gives them a chewy and hearty texture, making them perfect for dunking in milk or coffee.
- Baking soda: This helps the cookies rise and creates a soft and fluffy texture.
- Salt: A pinch of salt brings out the flavors in the cookie dough.
- Light butter (softened): Using light butter instead of regular butter will reduce the amount of fat and calories in your cookies without sacrificing flavor.
- Sugar substitute: I like to use Swerve as my sugar substitute because it measures 1:1 with traditional sugar, making it easy to swap out in recipes.
- Brown sugar: Adding brown sugar gives these oat flour
- Egg: This acts as a binding agent and helps to create a soft and chewy texture.
- Libby chocolate chips: No oat flour cookie is complete without some delicious chocolate chips! Feel free to use your favorite brand or try different flavors like white chocolate or peanut butter chips.

How to Make the Perfect Oat Flour Cookies
- Mix the Dry Ingredients: In a bowl, combine oat flour, baking soda, baking powder, and salt. Set aside.
- Cream the Butter and Sugars: In another bowl, beat the butter and sugars until light and fluffy. This usually takes about 2-3 minutes.
- Add the Eggs Beat the eggs one at a time, followed by the vanilla extract.
- Combine: Gradually add the dry ingredients to the wet mixture until just combined. Fold in the chocolate chips.


Baking the Cookies
- Preheat the Oven: Preheat your oven to 350°F (175°C) and line a baking sheet with parchment paper.
- Scoop the Dough: Use a cookie scoop to drop mounds of dough onto the prepared baking sheet, spacing them about 2 inches apart.
- Bake: Bake for 10-12 minutes or until the edges are golden but the centers are still soft. Allow the cookies to cool on the baking sheet for a few minutes before transferring them to a wire rack to cool completely.


Variations and Substitutions
- Nut Butter: Swap traditional butter or margarine with almond, cashew, or peanut butter for added protein and healthy fats. This not only enhances the nutritional profile but also imparts a rich, creamy flavor to your cookies.
- Natural Sweeteners: Instead of artificial sugars, consider using natural sweeteners like honey, maple syrup, or agave nectar. These options provide sweetness while offering additional nutrients and a lower glycemic impact.
- Gluten-Free Options: For those avoiding gluten, ensure that your oat flour is certified gluten-free. Combine it with other gluten-free flour like almond or coconut flour to create a delicious, gluten-free cookie.
- Vegan Choices: If you're looking for a vegan option, replace eggs with flaxseed meal mixed with water (1 tablespoon of flaxseed meal with 2.5 tablespoons of water per egg) or unsweetened applesauce to maintain moisture and binding without using animal products.
Equipment
- Mixing Bowls: A set of mixing bowls in various sizes will help you combine ingredients without spilling or mess. Glass or stainless steel bowls are durable choices.
- Measuring Cups and Spoons: Accurate measurements are crucial for baking success. Invest in a set of dry and liquid measuring cups and spoons.
- Rubber Spatula: This handy tool is perfect for scraping down the sides of bowls and ensuring that all ingredients are well-mixed.
- Baking Sheets: Non-stick or parchment-lined baking sheets will help your cookies bake evenly and prevent sticking.
- Cooling Rack: Once your cookies are baked, transferring them to a cooling rack allows them to cool down properly, maintaining their texture.
- Stand Mixer or Hand Mixer: While you can mix by hand, a stand mixer or handheld mixer can save time and energy, especially when combining ingredients smoothly.

Storing Oat Flour Cookies
Room temperature: Oat flour cookies can be stored at room temperature for up to 5 days. However, if you live in a hot and humid climate, they may only last 2-3 days before becoming stale.
Refrigerator: If you want your oat flour cookies to last longer, store them in the refrigerator for up to 2 weeks. Place them in an airtight container or wrap them tightly with plastic wrap.
Freezing: Oat flour cookies can also be frozen for longer storage. Place them in a freezer-safe container or zip-top bag, and they will last up to 3 months. When ready to eat, thaw at room temperature or heat in the oven for a few minutes to enjoy a freshly baked taste.
Tips for Baking with Oat Flour
Experimenting with Add-Ins: Don’t be afraid to get creative! Add nuts, dried fruits, or spices like cinnamon and nutmeg to your dough for extra flavor and texture.
Achieving the Right Consistency: Oat flour can sometimes result in crumbly dough. If this happens, add a tablespoon of milk or water until the dough comes together.
Boosting Flavor: Toast the oat flour lightly in a dry skillet before using it in your recipe to enhance its nutty flavor.

FAQs about Oat Flour Cookies
Making oat flour at home is simple and requires just one ingredient: rolled oats. Start by measuring out the desired amount of rolled oats, typically one cup for a standard batch of cookies. Place the oats into a high-speed blender or food processor. Blend them on high for about 30 seconds to 1 minute or until the oats reach a fine, flour-like consistency. It’s important to stop occasionally and scrape down the sides to ensure even blending. Once finished, sift the oat flour through a fine-mesh sieve to remove larger particles. Store your homemade oat flour in an airtight container in a cool, dry place, or refrigerate it for a longer shelf life. Using freshly ground oat flour enhances the flavor and nutritional value of your baking!
Yes, making the dough ahead of time is possible; it can enhance the overall taste and texture of your oat flour cookies. Allowing the dough to rest gives the flavors more time to meld, resulting in a richer end product. You can prepare and refrigerate the dough for a day or two before baking or freeze it for longer storage. When you're ready to bake, follow the steps for pre-baking from frozen or refrigerated dough and delight in warm, delicious cookies any time you desire!
Oat flour cookies are generally healthier due to the high fiber content and lower glycemic index of oat flour. They also contain essential nutrients like magnesium and iron, making them a nutritious treat.
