Ingredients for Oat Flour Chocolate Chip Cookies

The exact amounts of each ingredient are indicated in the recipe card at the end of the post. Toggle between US Customary (volume) and Metric (weights) for preferred measurement option.

These oat flour chocolate chip cookies are made with a handful of simple pantry ingredients. Each one plays an important role in creating a soft, tender cookie with rich chocolate flavor.

• Oat flour (certified gluten-free, as needed)
• Flaxseed meal
• Coconut sugar (see notes for alternatives)
• Almond butter (or the nut butter or seed butter you prefer)
• Vanilla extract
• Baking soda (not baking powder)
• Dark chocolate chips (certified gluten-free and/or vegan, as needed)

You will also need some water (I use filtered water from my tap) to make the cookie dough. Salt is optional. If using unsalted almond butter, I recommend adding a small pinch.

How to Make Oat Flour Chocolate Chip Cookies

Note that the complete directions are also in the recipe card below.

Step One: Preheat Oven & Prepare Baking Pan

Preheat the oven to 350F (180C). Line a large baking sheet with parchment paper (to prevent the cookies from sticking to the pan). You can also use a silicone baking mat.

Step Two: Whisk the Wet Ingredients

Whisk the almond butter, flaxseed meal, coconut sugar, vanilla extract and warm water in a medium mixing bowl until blended and smooth.

Step Three: Add the Dry Ingredients

Add the oat flour, baking soda, optional salt, and chocolate chips to the bowl of wet ingredients. Use a rubber spatula or large wooden spoon to stir and blend until completely combined into a thick cookie dough.

Step Four: Portion the Cookie Dough

Using a small cookie scoop or a heaping tablespoon measure, scoop 10 portions of the cookie onto the prepared baking sheet, spacing about two inches apart. With damp fingertips (dip in water), gently flatten the dough into circles (about 2 inches/ 5 cm in diameter).

Step Five: Bake Cookies

Bake the cookies in the preheated oven for approximately 8 to 11 minutes just set, pale golden, and the surface of the cookies appears dry (begin checking for doneness at 8 minutes).

Step Six: Cool Cookies

Let the cookies cool, on the cookie sheet, on a cooling rack for 1 minute. Using a pancake turner or other spatula, transfer the cookies from the baking sheet to a cooling rack, Cool completely.

Texture & Flavor

The natural fats from the almond butter and flaxseed meal give these oat flour chocolate chip cookies a soft, tender texture with lightly crisp edges. The flavor is reminiscent of traditional chocolate chip cookies, with a warm vanilla-scented dough that is just sweet enough to balance the melty dark chocolate chips.

How to Store Oat Flour Chocolate Chip Cookies

Store the cooled oat flour chocolate chip cookies in an airtight container:

• Room temperature: up to 2 days
• Refrigerator: up to 1 week
• Freezer: up to 6 months

Expert Tips for the Best Oat Flour Cookies

1. Use finely ground oat flour. Finely grind rolled oats in a blender or use store bought oat flour. Oats that are roughly ground in a food processor will produce cookies that are less tender and do not hold together as well.
2. Slightly flatten the cookies before baking. The cookies do not spread, so you need to use damp fingers to flatten the mounds of cookie dough before baking.
3. Do not overbake. Begin checking for doneness at the minimal suggested baking time (8 minutes). Continue checking every other minute if they are not set. The second batch of cookies will likely need less time if re-using the same baking sheet (it will be hot from first batch), unless you cool the baking sheet under cold water first.
4. Cool 1 minute on baking sheet. These cookies firm up as they cool. They will also be easier to transfer to the cooling rack afterwards.
5. Don’t skip the flaxseed meal. Flaxseed meal adds both fat (important for a tender texture) and structure to the cookies (in the absence of both eggs and gluten).

Ingredient Substitutions

If you need to adjust ingredients, here are a few tested substitutions.

• Can I use a different gluten-free flour instead of oat flour? I do not recommend substituting the oat flour. The ratio of wet to dry ingredients is formulated specifically for oat flour and other gluten-free flours or blends will alter the texture and structure.
• Can I use ground chia seeds in place of flaxseed meal? Possibly. I have only tested with flaxseed meal, but in theory, any equal weight of ground chia seeds should work as a substitute.
• Can I use other sweeteners in place of coconut sugar? Yes. Use an equal amount (1/3 cup) of your preferred granular sweetener, such as brown sugar, date sugar, or natural cane sugar.

Flavor Variations for Oat Flour Chocolate Chip Cookies

You can easily vary the flavor of the oat flour chocolate chip cookies with a few simple additions or changes:

If you need to adjust ingredients, here are a few tested substitutions.

• Nut Butters & Seed Butter. Use different varieties of smooth nut butter or seed butter in place of the almond butter, such as cashew butter, peanut butter, sunflower seed butter, or tahini.
• Warm Spices. Add 1/2 to 3/4 teaspoon of cinnamon, pumpkin pie spice, cardamom, allspice, or 1/4 teaspoon nutmeg to the cookie dough.
• Seeds & Nuts. Add 1/3 cup finely chopped nuts or seeds (raw or toasted) to the cookie dough. Pecans, walnuts, almonds, sunflower seeds, green pumpkin seeds (pepitas), and hazelnuts all work well.
• Chopped Dried Fruit. Swap the chocolate chips for an equal amount of chopped dried fruit, such as dried apricots, raisins, dried cranberries, dried cherries or dried blueberries.
