Hi friends!

I’m adding a classic cookie recipe to your arsenal today – Chocolate Chip Walnut Oatmeal Cookies. Everyone has a favorite chocolate chip cookie – a tried and true staple that never fails. For me, that’s these Chewy Gluten-Free Chocolate Chip Cookies. But it’s also good to have a few more go-to recipes, usually some with fun mix-ins!

Oatmeal Chocolate Chip Walnut Cookies

That’s where this recipe comes in! It’s a classic chewy chocolate chip cookie recipe with hints of cinnamon and lots of chopped walnuts, chocolate chips and oats mixed in.

If you, like me, do not actually love walnuts, you could swap in pecans like I often do! You could even use slivered almonds or chopped peanuts.

You could also swap chocolate chips for raisins for a different spin.

What makes these the best chocolate chip walnut cookies?

This recipe has the perfect ratio of mix-ins to cookie dough. The oats add some texture to basic cookie dough while the chocolate chips add the perfect amount of sweetness. But it’s the walnuts that make this cookie really shine. The understated walnut flavor really shines through in these cookies and they offer the perfect balance of crunch from the walnuts and chewiness from the dough.

Chocolate Walnut Cookies

In developing this recipe, my emphasis was on the walnuts and making them the star of the show. If you’d like a bigger focus to be on the chocolate, there are a few things you could do. Leave out the oats and:

• Use dark chocolate – It has a richer, slightly stronger flavor which will make it stand out more.
• Use chocolate chunks – Instead of using chocolate chips, grab a bar of your favorite dark chocolate and chop it up into larger chunks. They’ll take up more space in the cookies and make their presence known!
• Add cocoa powder – Add 1/3 cup cocoa powder to your dough when you add the dry ingredients for a chocolate walnut cookie everyone will love!

Chocolate Oat Walnut Cookies

If you love the idea of oats and walnuts together but also want a chocolate cookie, feel free to follow this recipe as it’s written but add 1/3 cup cocoa powder when you mix in the dry ingredients.

Why add Oatmeal to Chocolate Chip Walnut Cookies?

As a Registered Dietitian, oats are one of my favorite additions to muffins, cookies and other baked goods. They’re a whole grain and a great source of fiber. They also mix seamlessly into most doughs and batters and are an easy way to add some nutrient density to a recipe.

They also add a nice texture and are a great source of vitamins and minerals.
