A twist on the classic
While nothing beats the classic oatmeal raisin cookies, I think a twist on a classic recipe could be fun and delicious. This recipe calls for walnuts instead of raisins which makes it chunky and really tasty. These cookies are crunchy with a hint of cinnamon that makes them perfect for anytime of the year!
The best thing about this oatmeal cookie recipe is that you can make the dough ahead of time and chill it in the fridge for 2 hours up to 3 days. You can also freeze the dough or the baked cookies to enjoy later!
3 tips for the best oatmeal cookies
- Use old-fashioned oatmeal: There are several types of oatmeal available at a regular supermarket: quick. old fashioned, steel cut, etc. Make sure to use old fashioned oatmeal when it comes to cookies.
- Room temperature ingredients: Keep the butter and the eggs at room temperature, they'll mix much better.
- Don't overbake: Remember, when you remove the baking sheet from the oven and leave it on the counter, the cookies will keep baking for a few more minutes since the baking sheet is still hot. It's best to remove the cookies when they're a bit underdone so they don't get hard and too crispy after they cool.
Ingredients
- Butter: It's best to use unsalted butter that's at room temperature. Soft butter mixes very well wit the sugar and eggs. Make sure the butter isn't melted.
- Sugar: For this recipe you need both brown sugar and granulated sugar.
- Egg: Again, you'll need room temperature egg.
- Oatmeal: Old fashioned oatmeal works for this recipe.
Quick oatmeal vs old fashioned oatmeal
To make this recipe, I used old fashioned oatmeal as I almost always do when it comes to baked oatmeal cookies. Old fashioned oatmeal gives a nice texture to cookies and it makes them pretty chewy. Check out this article to learn more about old fashioned oatmeal vs quick oatmeal for baking.
Instructions
Start with creaming butter and sugar in a large bowl. Add in the egg and mix well until fully combined. Add in flour, oatmeal, cinnamon and baking powder. Stir using a spatula or a wooden spoon. Then add chopped walnuts and stir well. Refrigerate the cookie dough for about two hours.
Preheat the oven to 350ºF. Line a baking sheet with parchment paper and scoop out the oatmeal cookie dough onto the baking sheet using a cookie or ice cream scoop. Place them two inches apart from each other to give them room to spread. Bake in the oven and cool completely on a baking sheet before serving.
Pro tip: Make sure not to over bake the cookies otherwise they'll turn hard and dry. The cookies are ready once the edges are set and golden and the middle is still soft.
Frequently asked questions
I usually bake oatmeal cookie for about 12-15 minutes until the edges are golden brown. The cookies are usually pretty soft once they're out of the oven and you can transfer them to the wire rack after 5-10 minutes.
You can make the cookie dough and keep it in the fridge for up to 3 days. When ready to bake, simply follow the baking instructions in the recipe card. You can also bake the cookies and keep them in an airtight container a couple of days in advance.

To make these walnut oatmeal cookies gluten free, use 1:1 gluten free all purpose flour. As for dairy free, I don't recommend switching ingredients since alternatives such as coconut oil or flax eggs would change the flavor and texture of the cookies.

I buy butter sticks from Costco so when the recipe ask for a stick of butter - my stick is only 1/2 cup butter. Is this the same?
Shadi HasanzadeNemati
Yes, a stick is equal to 1/2 cup butter 🙂
Darc Mansfield
All sticks are a half cup so you're ok with what you bought
