These chewy oatmeal cookies are perfect for breakfast on the go. A simple and easy recipe packed with oats to keep you full for a long time. This is my basic recipe, which you can use to make so many other variations, from chocolate chips to dried fruit and nuts, as well as candy.

If I ever need breakfast on the go, this is it. I love oats and I have oatmeal porridge or granola every day for breakfast. A long time ago, when I traveled often, this was the cookie I always had in my bag. It was the best breakfast for me. And, it still is the perfect snack at any time of the day.
About these cookies
This is a standard cookie recipe and you don't even need to get your stand mixer out. As long as all your ingredients are at room temperature, this will give you the most delicious oatmeal cookies you have ever tasted.
The best thing about these cookies for me is the crisp edges with a soft and chewy center. It's the best of both soft, chewy and crisp all in one cookie.
This is my basic oatmeal cookie recipe and I use it to make my oatmeal raisin cookies, oatmeal chocolate chip cookies, and oatmeal M&M cookies (this gets my kids eating oatmeal cookies). I even make some with peanut butter chips.

Ingredients and substitutes
- Oatmeal - You want to use old-fashion rolled oats for this cookie. Quick-cooking oats won't do well in this recipe, but if that's all you have, I recommend my raisin and pecan oatmeal cookies with quick-cooking oats.
- Flour - I use regular plain flour, all-purpose flour. That's all you need.
- Brown sugar - I prefer light brown sugar because it adds that nice chewy texture to it but still gives the cookies a nice light brown color.
- White sugar - Adds crispness and structure to the cookie. It ensures the cookie doesn't break so easily.
- Butter - I always use unsalted butter, but if salted butter is all you have then use it and omit the salt in the recipe.

Step by step instructions
- Preheat the oven at 180 C / 390 F.
- Combine together - flour, cornstarch, baking powder, baking soda, salt, and cinnamon powder. Set aside.
- Cream butter and sugar until light and fluffy.
- Add eggs and egg yolk.
- Followed by the oatmeal. Combine well.
- Then, add the flour mixture.
- Use a cookie scoop or use 2 tablespoon to drop spoonfuls on a baking tray.
- Bake them in a preheated oven for 10 to 12 minutes or until the edges have a slight color but the center is set, not wet.
- Cool on the baking tray for 10 minutes. Then, transfer to a wire rack to cool completely.
