- Healthy cookies with a satisfyingly crunchy texture, featuring oatmeal as the star ingredient.
- Grass-fed butter takes the flavor to the next level. You can make them wheat-free by using rice flour and coconut flour (*see our notes below).
- Super easy to shape using the "chill and slice" method. Baking time is around 15–17 minutes at 200°C (390°F).
- Endlessly customizable with nuts, chocolate chips, and spices. When we tested them, a cinnamon and walnut combo was a huge hit!
The Charm of Oatmeal Cookies & What This Guide is All About
We’ve put together an easy-to-follow recipe and tips for making homemade oatmeal cookies—the perfect guilt-free snack for when you're feeling a little peckish. The best part about making them at home is that you can easily control the amount of sugar and oil. When we tested this out, we found that chilling the dough and slicing it thinly made it so much easier to get uniform shapes and an even bake. It’s also incredibly fun to see how just a few little tweaks can completely change the texture and flavor!
Ingredients (Makes about 18–22 cookies)
- Oatmeal (Rolled oats) 100g
- Rice flour 80g
- Coconut flour 20g
- Baking powder 1/4 tsp
- Grass-fed butter (room temperature) 100g
- Egg 1
- Lakanto (or your preferred sweetener) 80g
- Chocolate chips 20g (dark/bitter recommended)
- Cashew nuts (roughly chopped) 20g
- Salt a pinch
*These measurements are just a guide. Feel free to adjust the sweetness and the amount of nuts to your liking.
Instructions & Baking Tips
- Bring the butter to room temperature and cream it in a bowl. Add the Lakanto and mix well, then add the egg and mix until smooth. Emulsifying the mixture well at this stage helps create even air bubbles in the dough, resulting in a lighter, fluffier bake.
- In a separate bowl, sift together the rice flour, coconut flour, baking powder, and salt. Add this dry mix to your butter mixture and stir. Make sure no dry, powdery spots remain!
- Fold in the oatmeal, chopped cashews, and chocolate chips with a rubber spatula. If the dough feels a bit too stiff here, add 1 to 2 teaspoons of milk or soy milk to adjust the consistency.
- Wrap the dough in plastic wrap, shaping it into a log, and let it firm up in the fridge for at least 30 minutes (an hour is perfectly fine, too). In our testing, we found that if the dough isn't chilled enough, it tends to crumble when shaping. Chilling it thoroughly makes slicing a breeze and reduces uneven baking.
- Slice the chilled dough log into rounds about 5mm thick and arrange them on a baking sheet. If you like, sprinkle a little sea salt on top.
- Preheat your oven to 200°C (390°F) and bake for 15–17 minutes. If you prefer a crunchier cookie, bake them a little longer; if you're team chewy, pull them out a bit earlier. You'll know they're ready when the edges turn a lovely, light golden brown.
Pro Baking Tips
- Every oven has its own quirks, so baking times can vary. It's always best to keep an eye on them the first time around and add extra time if needed.
- Spacing the cookies evenly on the tray helps prevent uneven baking. Don't overcrowd them!
- They will be quite soft right out of the oven. Letting them cool directly on the baking sheet helps them set without losing their shape.
Fun Variations & Ingredient Substitutions
This recipe is incredibly versatile. Here are a few of our absolute favorite ways to mix things up:
- Flour swaps: Replacing a portion of the rice flour with almond flour adds a wonderful, nutty aroma. Using all almond flour will give you a much moister cookie.
- Sweetener swaps: If you use maple syrup or honey instead of Lakanto, you'll need to adjust your liquids (the dough will become a bit softer).
- Egg-free option: Want to make these vegan? You can easily substitute the egg with a "flax egg" (ground flaxseed mixed with water).
- Nuts & flavors: Adding a dash of cinnamon or nutmeg brings out a beautiful depth of flavor. We tried a cinnamon and walnut combo, and it was the absolute perfect pairing for our morning coffee!
- A note on gluten-free: Depending on the brand, oatmeal can sometimes be cross-contaminated with wheat. If you need these to be strictly gluten-free, be sure to use oats specifically labeled "certified gluten-free."
Storage Tips & Nutritional Info
Store your cookies in an airtight container for 2 to 3 days at room temperature, or up to 5 days in the fridge. If you want to freeze them, wrap each cookie individually in plastic wrap and pop them into a zip-top bag; they'll keep for about a month. Lightly warming them in a toaster oven before eating will bring right back that fresh-baked flavor!
Nutritionally speaking, you're getting a great dose of dietary fiber and beta-glucan from the oats. However, because of the nuts and butter, they do pack a fair amount of calories, so we recommend keeping an eye on your portion sizes. Exact calorie counts will vary depending on the specific ingredients and amounts you use, so if you're tracking your macros, it's best to calculate based on your exact ingredient list.
Final Thoughts
Oatmeal cookies are such a versatile treat—you can completely change their texture just by playing around with the ingredients, mixing methods, and baking times. In the recipe we tested, the "chill and slice" method made shaping a breeze, and the rich flavor of the grass-fed butter made them incredibly satisfying. They're perfect for a quick snack on busy days or a wholesome treat for the kids. We hope you have fun experimenting and finding your own perfect variation!
