Oatmeal walnut cookies are chunky and tasty. Have these chunky oatmeal cookies  with a glass of milk to taste all the happiness!

Another oatmeal cookie recipe for your oatmeal cookie cravings! Some our favorite oatmeal recipes are cranberry oatmeal cookies, chocolate chip oatmeal cookies and maple oatmeal cookies. Oatmeal walnut cookies are chunky and tasty. Have these chunky oatmeal cookies  with a glass of milk to taste all the happiness!

A chunky twist on easy oatmeal cookies!

Oatmeal walnut cookies are a twist on an all-time favorite. Inspired by the man of the family!

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!)

Oatmeal walnut cookies ingredients

The ingredients you need for these cookies are pretty basic: butter, eggs, oatmeal, flour. 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.

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

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 350F. 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.

Walnut oatmeal cookie variations

  • Oatmeal raisin walnut cookies: add 1/2 cup raisins to the batter with the walnuts.
  • Oatmeal cranberry 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 oatmeal walnut cookies are crunchy with a hint of cinnamon that makes them perfect for anytime of the year!
