Why oat flour? Oat flour is a favorite for good reason: it’s a whole grain, naturally gluten‑free (when certified), and provides more fiber and protein than white all‑purpose flour. It works well in quick bakes like pancakes and muffins, and gives these cookies a tender, slightly different texture that’s delightfully chewy.

Ingredient Notes
- Oat flour – Both homemade and store‑bought oat flour work well. For gluten sensitivity or celiac disease, choose certified gluten‑free oat flour to avoid cross‑contamination.
- Coconut sugar – An unrefined option with a brown‑sugar flavor. Brown sugar can be substituted if needed.
- Tapioca starch – Adds structure and chewiness to the cookies.
- Chocolate chips – Use dairy‑free chips for a vegan option, or any preferred chocolate chips.
See the recipe card below for the complete ingredient list.
Sara’s clean food tip: To reduce exposure to pesticide residues like glyphosate, choose organic oat flour when possible. For chocolate, select chips made from simple ingredients (chocolate liquor/cocoa, cane sugar, cocoa butter) and consider organic or Fair Trade options when available.
Substitutions and Variations
- For dairy‑free cookies, substitute softened coconut oil or vegan butter and use dairy‑free chocolate chips.
- Add about ½ cup chopped walnuts or pecans for a nutty variation.
- For a salty‑sweet finish, sprinkle flaky sea salt on the cookies right after they come out of the oven.
How to Make Oat Flour Chocolate Chip Cookies
- Step 1: Preheat oven to 350°F and line two baking sheets with parchment paper. Cream the butter and coconut sugar for about 1 minute.
- Step 2: Add the egg, extra egg yolk, and vanilla. Mix on medium‑low until combined.
- Step 3: Add baking soda, salt, tapioca flour, and half of the oat flour. Mix on low until nearly combined.
- Step 4: Add the remaining oat flour and mix until the dough is evenly combined.
- Step 5: Fold in the chocolate chips so they’re distributed throughout the dough.
- Step 6: Scoop about 2 tablespoons of dough per cookie onto the prepared sheets, spacing them roughly 2 inches apart.
- Step 7: Bake at 350°F for 8–10 minutes, until edges are just set and lightly browned. Allow cookies to rest on the sheet for 5 minutes before transferring to a cooling rack.
Top Tip: Use a spring‑loaded cookie scoop for easy portioning — oat flour dough tends to be a bit stickier than traditional dough.
Is Store‑Bought or Homemade Oat Flour Best?
Both homemade and store‑bought oat flour produce excellent results. Making oat flour at home is inexpensive and easy: blend rolled oats in a high‑speed blender until finely ground. If you don’t have a powerful blender, a packaged oat flour works perfectly and saves time.
Helpful Tips and Notes for the Best Cookies
- Bring butter to room temperature at least 2 hours before baking. If short on time, microwave for about 7 seconds to soften.
- When measuring oat flour, scoop into the cup and level off with a knife to avoid overpacking and dry cookies.
- Do not overbake — remove when edges are set and centers still look slightly soft; cookies will continue to firm as they cool.
- Avoid overmixing to keep the texture chewy rather than cake‑like.
- For perfectly round cookies, gently nudge warm cookies with a round cutter after baking to shape the edges.
Recipe FAQs
They are naturally gluten‑free when you use certified gluten‑free oats or oat flour. Oats can be processed in facilities that also handle wheat, so choose certified products if gluten sensitivity or celiac disease is a concern.
Oat flour lacks gluten, so structure depends on the right moisture and fat balance. Crumbliness often results from too much flour (avoid packing the measuring cup) or overbaking. Measure carefully, slightly underbake, or add a tablespoon or two of milk if needed.
No — chilling isn’t necessary and can limit spread. If you prefer thicker, puffier cookies, chilling will help, but it’s optional.
Oat flour is a whole grain and typically provides more fiber, protein, and nutrients than refined white flour, making it a nutritious alternative.
Yes — scoop dough balls and freeze them on a sheet, then transfer to a freezer container for up to 3 months. Thaw to room temperature before baking for best spread; baking from frozen will give less spread.
Storing and Freezing
Room temperature: Store in an airtight container for up to 3 days, or refrigerate to extend freshness a few more days.
Freezer: Fully cooled cookies freeze well for up to 3 months in a freezer‑safe container.
Freeze dough to bake later: Scoop dough onto a sheet, freeze until solid, then store in a freezer bag or container for up to 3 months. Thaw to room temperature before baking for best spreading; baking from frozen yields less spread.
