The Basics of Oat Flour & Why It Works So Well for Cookies

Oat flour is a popular choice for baking, especially for those who prefer a gluten-free diet. It’s easy to digest and packed with health benefits.

Oat flour is naturally high in fiber, which supports digestion, and provides a good amount of protein, making it a more nutritious option compared to regular all-purpose flour.

It also contains essential nutrients like manganese, iron, and magnesium, which contribute to overall health.

When used in cookies, oat flour gives them a chewy texture and a subtle, nutty flavor. Plus, it’s often considered a healthier alternative to traditional flour because it’s less processed.

However, if you need the cookies to be completely gluten-free, be sure to choose certified gluten-free oat flour to avoid cross-contamination.

No. of Servings: 16 cookies
Baking Time (Minutes): 10
Calories: 94 per cookie

Ingredients

Ingredient Amount
Oat Flour 1 ½ cups + 1 ½ tbsp
Butter ½ cup
Brown Sugar ⅓ cup
Egg 1 large
Vanilla Extract 1 tsp

Step 1: Cream the Butter and Sugar

cream-the-butter

Begin by softening the butter at room temperature. In a medium bowl, beat the softened butter and brown sugar together using an electric mixer.

Mix until the butter and sugar are light and fluffy, which will take about 2 minutes. This step helps create a smooth texture in the cookie dough. The air incorporated into the butter-sugar mixture will give the cookies a soft, chewy bite once they’re baked.

Step 2: Add the Egg and Vanilla

add-the-egg-vanilla

Once your butter and sugar are well combined, crack the egg into the bowl and add the vanilla extract. Use the mixer to beat these ingredients together until fully incorporated.

The egg acts as a binder, helping hold the cookie dough together and giving it structure. The vanilla will enhance the flavor of the cookies, balancing out the sweetness of the sugar and adding depth to the overall taste. Continue mixing for another 1-2 minutes.

Step 3: Combine Dry Ingredients

In a separate bowl, whisk together the oat flour. Slowly add the oat flour to the butter mixture, stirring gently with a spatula or spoon. It’s important to mix the ingredients until fully combined, but avoid overworking the dough.

The consistency should be slightly thick but soft enough to scoop. If the dough feels too dry, you can add a teaspoon or two of water to bring it together, but be careful not to add too much liquid to keep the dough from becoming too sticky.

Step 4: Shape and Bake

shape-and-bake

Once your dough is ready, scoop it into tablespoon-sized balls. Use your hands to gently roll the dough into balls and place them on a lined baking sheet, leaving about 2 inches between each cookie.

Flatten each dough ball slightly with your hands or a fork. This ensures that the cookies bake evenly and have a nice, round shape. Preheat your oven to 350°F and bake for 10 minutes, or until the edges of the cookies are lightly golden. Keep an eye on them to avoid over-baking.

Step 5: Cool and Serve

cool-and-serve

After removing the cookies from the oven, let them cool for a few minutes on the baking sheet. This step helps them firm up so they don’t break apart. Once they are firm enough to handle, transfer them to a wire rack to cool completely.

The cookies will continue to firm up as they cool, giving them the perfect chewy texture. Once cooled, enjoy your delicious oat flour cookies, or store them in an airtight container for up to 5 days.

Ingredient Amount
Oat Flour 1 ½ cups

Chocolate Chips ¾ cup

Step 1: Cream the Butter and Sugar

cream-the-butter-and-sugar

Begin by softening the butter at room temperature for easier mixing. In a medium bowl, use a hand mixer to beat the softened butter and brown sugar until the mixture is light and fluffy. This step should take about 2 minutes.

The air incorporated into the butter and sugar mixture helps give the cookies their soft, chewy texture. Creaming the butter and sugar also ensures an even consistency throughout the dough for perfect results.

Step 2: Add the Egg and Vanilla

add-egg-and-vaniila

Once the butter and sugar are fully combined, crack in the egg and add the vanilla extract. Beat the mixture for another 1-2 minutes until everything is fully incorporated.

The egg will bind all the ingredients together, giving the dough structure and helping the cookies hold their shape while baking. Vanilla extract deepens the flavor of the cookies, enhancing the sweetness from the sugar and creating a well-rounded, delicious taste.

Step 3: Combine Dry Ingredients

combine-dry

In a separate bowl, whisk together the oat flour and a pinch of salt. Slowly add this dry mixture to the wet ingredients, stirring gently with a spatula or spoon until fully combined.

The oat flour will make the dough thick but still soft. Be careful not to over-mix the dough as this can cause the cookies to be dense rather than chewy. If the dough feels too dry, you can add a teaspoon of water to help bring it together without making it too sticky.

Step 4: Add Chocolate Chips and Bake

Once the dough is mixed, fold in the chocolate chips. Gently stir them in until evenly distributed throughout the dough. Preheat your oven to 350°F (175°C) and line a baking sheet with parchment paper.

Using a tablespoon or a cookie scoop, form dough balls and place them on the baking sheet about 2 inches apart. Flatten the balls slightly with your hands or a fork. Bake for 10 minutes, or until the edges are golden and the centers are set. These cookies will stay chewy as they cool.

Step 5: Cool and Serve

Let the cookies cool on the baking sheet for a few minutes before transferring them to a wire rack. This allows them to firm up without breaking apart. After they’ve cooled completely, you can enjoy them or store them in an airtight container for up to 5 days.

These cookies are perfect for any occasion, and their soft, chewy texture is sure to satisfy your chocolate chip cookie cravings!
