Coconut Flour Oatmeal Cookies
I remember the first time I swapped all-purpose flour for coconut flour in a cookie — the texture surprised me in the best way. These coconut flour oatmeal cookies are lightly sweet, pleasantly cakey, and come together faster than you’d expect. They’re perfect for a weekday treat, a lunchbox pick-me-up, or when you want an oat-forward cookie that’s not heavy. If you like coconut-forward bakes, you might also enjoy this take on coconut oatmeal cookies I tried before: coconut oatmeal cookies.
Why you’ll love this dish
This recipe balances coconut flour’s absorbency with rolled oats so the cookies stay tender instead of drying out. They’re quick to mix in one bowl, flexible with ingredients (butter or coconut oil; brown sugar or coconut sugar), and kid-approved for their familiar oatmeal flavor. Make them when you want something that feels homey but also a touch lighter than traditional cookies.
“Soft in the center, lightly crisp at the edges — these became my go-to afternoon cookie.” — a regular tester
If you’ve tried almond-based versions, you’ll see a different crumb and coconut flavor; compare notes with this almond flour oatmeal recipe to understand the texture swap: almond flour oatmeal cookies.
How this recipe comes together
Overview: Whisk the dry ingredients, blend the melted fat with eggs and vanilla, fold wet into dry, scoop, and bake. Expect sticky dough — coconut flour soaks up liquid fast — but the oats provide structure so you don’t need extra flour. Total hands-on time is about 10–15 minutes, with 10–12 minutes in the oven.
If you want a slightly different mixing order or a one-bowl approach, there’s another method I tested: another coconut oatmeal method.
What you’ll need
Key ingredients (makes roughly 18–24 cookies, depending on size):
- 1 cup coconut flour
- 1 cup rolled oats
- 1/2 cup brown sugar or coconut sugar (use coconut sugar for lower glycemic index)
- 1/2 cup butter or coconut oil, melted (adds flavor; coconut oil increases coconut aroma)
- 2 eggs
- 1 teaspoon vanilla extract
- 1/2 teaspoon baking powder
- 1/4 teaspoon salt
Notes and substitutions inline:
- Rolled oats: use old-fashioned oats for chew; quick oats will make a softer crumb.
- Sugar: brown sugar gives deeper flavor and chew; coconut sugar is a one-to-one swap.
- Fat: salted butter adds seasoning; if using coconut oil, consider adding a pinch more salt.
- Eggs: provide lift and structure — vegan swaps require careful testing (flax egg may yield denser cookies).

Step-by-step instructions
- Preheat and prepare. Set the oven to 350°F (175°C). Line a baking sheet with parchment paper.
- Mix dry ingredients. In a large bowl, whisk coconut flour, rolled oats, brown or coconut sugar, baking powder, and salt until evenly blended.
- Combine wet ingredients. In a separate bowl, whisk the melted butter or coconut oil with the eggs and vanilla until smooth.
- Bring dough together. Pour the wet mix into the dry ingredients and stir until the dough clumps and looks slightly sticky. If it seems too dry, add 1–2 teaspoons of milk and mix again.
- Portion cookies. Use a cookie scoop or tablespoon to drop spoonfuls onto the prepared sheet. Space them about 2 inches apart and gently flatten each mound with the back of the scoop or a fingertip.
- Bake. Put the tray in the oven and bake 10–12 minutes. Look for lightly golden edges and centers that look set but not browned.
- Cool properly. Let the cookies rest on the baking sheet for 3–5 minutes, then transfer to a wire rack to cool completely. This helps them finish setting without breaking.
Best ways to enjoy it
Serve these with a cold glass of milk, coconut milk latte, or a simple afternoon tea. For a brunch spread, plate them with fresh fruit and yogurt. To make an indulgent sandwich cookie, spread a thin layer of nut butter or whipped cream between two cookies. You can also crumble them over vanilla ice cream for a quick crunchy topping.
Storage and reheating tips
Store cooled cookies in an airtight container at room temperature for up to 3 days. For longer keeping, refrigerate up to 7 days. To freeze: layer cookies between parchment in a freezer-safe container for up to 3 months. Thaw at room temperature. Reheat briefly in a 300°F oven for 4–6 minutes or microwave one cookie for 8–12 seconds if you want that just-baked warmth. Always let cookies cool completely before sealing to avoid condensation and sogginess.
Pro chef tips
- Measure coconut flour carefully; it’s highly absorbent — spoon it into the cup and level, don’t scoop directly with the measuring cup.
- Melted—but not hot—fat prevents cooking the eggs when you combine ingredients. Let butter or oil cool slightly.
- If your dough feels crumbly, don’t panic: add liquid by the teaspoon (milk, almond milk, or an extra egg white) until it binds.
- Flip the baking sheet halfway through if your oven has hot spots for even browning.
- For a chewier cookie, use brown sugar and press slightly flatter before baking. For cake-like cookies, leave them taller.

Creative twists
- Chocolate chip: fold in 1/2 cup dark or semi-sweet chips.
- Spiced: add 1/2 teaspoon cinnamon and a pinch of nutmeg for warmth.
- Citrus-kissed: fold in 1 teaspoon finely grated orange zest with the vanilla.
- Nutty boost: stir in 1/3 cup toasted chopped pecans or walnuts.
- Lower-sugar: reduce sugar to 1/3 cup and add 1–2 tablespoons maple syrup for moisture.
- Vegan attempt: replace eggs with flax eggs (1 tablespoon ground flax + 3 tablespoons water per egg) but expect a denser texture.
Helpful answers
Q: Are these cookies gluten-free?
A: Yes, if you use certified gluten-free oats. Coconut flour itself is gluten-free, but oats are often cross-contaminated unless labeled GF.
Q: Can I make these without eggs?
A: You can try flax eggs (1 tbsp ground flax + 3 tbsp water per egg), but the result will be denser and more fragile. Coconut flour needs binding — eggs give structure — so proceed with caution.
Q: My cookies turned dry. What went wrong?
A: Most likely too much coconut flour or not enough liquid. Measure coconut flour properly and add a teaspoon or two of milk or an extra egg if the dough is crumbly.
Q: How long do they take from start to finish?
A: About 25–30 minutes total — 10–15 minutes prep and 10–12 minutes baking.
Q: Can I add mix-ins like raisins or seeds?
A: Yes. Fold in up to 1/2 cup total of raisins, seeds, or nuts. For raisins, consider soaking briefly to keep them plump.
