Chewy Oatmeal Cookies, just like Grandma used to make, are the best cookies that take you straight back to your childhood!
Full of chewy oats, brown sugar, walnuts, and spices, you just can't beat the taste and texture of these classic homemade cookies. This chewy oatmeal cookie recipe will become a favorite!

Chewy Oatmeal Cookies are, not surprisingly, a favorite of a lot of people. What's not to love? They're sweet, super chewy, and the oatmeal tricks your brain into thinking they're healthy!
I've made many cookies in my day. From what I call anytime cookies like Birthday Cookies with sprinkles and Toasted Macadamia Coconut Cookies, to cookies that are especially popular during holidays like Christmas and Valentine's Day... I will never turn down a freshly made cookie.
How to make oatmeal cookies:
- As with any cookie recipe, you'll start by preheating your oven and lining a baking sheet with silpat or parchment.
- In a medium bowl or using your stand mixer, you will cream together the butter and sugars. Next I like to beat in the eggs one at a time, followed by the vanilla. You will combine the dry ingredients in a separate bowl and stir them into the creamed mixture. Finally, you'll mix in the oats and nuts.
- You'll get the best results if you use a small or medium cookie scoop and drop dough 2 inches apart on cookie sheet. I like to flatten each cookie slightly.
- Bake for exactly 8 minutes in preheated oven. Any longer and you'll end up with crispy cookies. Allow cookies to cool on baking sheet for 5 minutes before transferring to a wire rack to cool completely.

How to make oatmeal cookies chewy:
There are two factors that make these cookies chewy.
First has to do with the bake time. You'll pull them out of the oven when they don't look fully cooked and the allow them to sit on the hot cookie sheet for a bit of time. This allows them to finish cooking but not get overly crisp.
The second factor is the brown sugar. I find that using a combination of brown sugar with a smaller amount of granulated sugar leads to a more chewy cookie.
Be sure to store your cookies in an airtight container to keep them fresh and chewy.

I made these cookies with gluten free flour and cane sugar vs beet sugar otherwise followed the recipe exactly. My husband said these were the best oatmeal cookies I have ever made. Will definitely use this recipe again.
Darcey
Delicious and easy! I made oatmeal cream pie cookies with canned vanilla icing in between two cookies.
They were a huge fan favorite all around here!
Susan
I did exactly what you said including flattening a little bit. They are really flat. Is there supposed to be a little baking powder (maybe 1/2 teaspoon? Also, I live in high altitude so wonder if that makes a difference?
Krissy
Yes, altitude and freshness of baking soda could have an impact. I would definitely add a bit of baking powder or increase flour a bit next time to see if it helps.

I have been making these since my first baby was born in 2019 and they work well for lactation! Also they stay chewy for over a week and are a great bedtime snack for a sweet tooth!
