    A chunky twist on easy oatmeal cookies!

    Cookies are Kyle’s favorite snack and oatmeal raisin is his favorite type of cookie. He really likes these Happy Thumbprint cookies, too. (Honestly, everyone loves these- they vanish in an hour!) These cookies are a twist on a childhood favorite. By adding walnuts to classic oatmeal cookies, we have a little crunch in every bite that makes these cookies irresistible!

    Walnut oatmeal cookies ingredients

    The ingredients you need for these cookies are pretty basic:

    • Butter
    • Brown sugar
    • Granulated sugar
    • Egg
    • Oatmeal
    • Cinnamon
    • Flour
    • Baking powder

    That’s pretty much it. You have to let the dough chill in the fridge for 2 hours so they keep their shape and taste better. Or you can simply make the dough the night before and refrigerate the cookie dough overnight. 

    Oatmeal Walnut Cookies are easy and simple to make. They are perfect for the holidays.

    Quick oatmeal or 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.  

    How to make oatmeal walnut cookies

    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.

    How long should I bake oatmeal cookies for?

    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.

    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.  

    Walnut oatmeal cookie variations

    • Oatmeal raisin walnut cookies: add 1/2 cup raisins to the batter with the walnuts.
    • Cranberry oatmeal walnut cookies: add 1/2 cup dried cranberries to the cookie dough with the walnuts.
    • Oatmeal chocolate chip walnut cookies: use 1/2 cup chocolate chips in the cookie dough while adding the walnuts.

    These walnut oatmeal cookies are crunchy with a hint of cinnamon that makes them perfect for anytime of the year!

      Oh how I love oatmeal cookies! And these are the absolute perfect combination of chewiness and crunch. I did add pecans instead of walnuts because they are what I had on hand and they still came out awesome. And don’t get me started on that touch of cinnamon – I can see why your son likes your cookies so much!
