How To Make Oatmeal Walnut Cookies

It’s a quick and easy treat you can make at any time.

Ingredients:

  • All-purpose flour
  • Unsalted butter – at room temperature
  • Brown sugar
  • White Sugar
  • Egg
  • Oats –Rolled oats, which are also known as old-fashioned oats or traditional oats, are ideal for this recipe because they add texture to the cookies. But you can use instant oats or quick oats too.
  • Walnuts
  • Vanilla extract
  • Baking soda.
  • Pinch of Salt

Tools:

  • Stand mixer or hand mixer
  • Rubber spatula

Directions:

  1. Preheat the oven to 350F/180C.
  2. In a stand mixer with the paddle attachment beat the butter until soft and fluffy.
  3. Stir in white and brown sugar gradually so they incorporate better and beat until well combined.
  4. Then add the vanilla and egg.
  5. In a bowl mix the flour, baking soda, and salt.
  6. Add the flour mixture to the butter mixture beating until is well incorporated.
  7. Mix in the oats in two parts so they’re easier to incorporate.
  8. Finally, add the walnuts and mix well. I like using a rubber spatula for this part.
  1. Let the dough chill in the fridge for at least 30 minutes.
  2. In a baking tray lined with parchment paper or aluminum foil greased and place small balls of dough with enough space in between for them to grow. 
  1. Bake for 8-12 minutes or until golden brown, especially on the edges.
  1. Take them from the oven, and let them cool on a wire rack.
  2. Serve and Enjoy!

Baking Tips

  • For extra flavor try toasting your walnuts a little bit before putting them in your cookie dough, take a little more time to cook them in the oven. This process makes their flavor stronger and brings out their natural oils, making your cookies taste more rich.
  • If you want to add raisins to it, put them in hot water for 10-15 minutes before adding them to the dough. This easy tip makes the raisins in the cookies plump, juicier, and softer. Also, it stops them from becoming hard and difficult to chew.
  • Let the dough cool down and let it get cold in the refrigerator for at least an hour, or even all night. Cooling helps the flavors mix well, makes the texture better, and stops the cookies from spreading too much when baked. You will have cookies that are big, soft, and made perfectly.
  • Try using different spices to make your oatmeal cookies extra special like cinnamon, powdered cardamom for a cozy and slightly citrusy taste, or a touch of nutmeg for a gentle and fragrant boost.
  • Add some citrus flavor to your cookies by mixing in a small amount of lemon, orange, or grapefruit zest into the dough. The tangy citrus flavor will go well with the nutty taste of the walnuts and the oats.
  • Add pieces of your favorite chocolate chips to oatmeal cookies with walnuts. The mix of chocolate, walnuts, and oats will make a delicious treat for chocolate lovers.

Make Ahead and Freeze

If you want to have cookies ready to bake whenever you want, divide the dough into small balls the size of cookies and put them in the freezer on a baking sheet.

After the dough balls have become frozen, move them into a bag that can be sealed again and put back in the freezer. It can last for up to 3 months.

Whenever you want to make cookies, just grab some cookie dough, let it warm up a bit, and bake them like usual. This way, you can have delicious oatmeal walnut cookies whenever you like.

Storing

You can store these cookies in an airtight container, cookie jars or tins for up to 3 to 4 days. Don’t have any of these? No problem a zip-lock plastic bags work well too.

Frequently Asked Questions

Can I substitute the walnuts with a different nut?

Yes, You can substitute walnuts with other nuts like pecans, almonds, or macadamia nuts if you prefer. Make sure to crush or cut them into pieces that are all the same size so that they can be evenly spread out in the cookies.

Can I use instant oats instead of rolled oats?

While instant oats can be used as a substitute, keep in mind that they have a finer texture and may affect the overall chewiness of the cookies. Rolled oats provide a heartier texture and better structure. If you only have instant oats, try pulsing them a few times in a food processor to achieve a more coarse consistency.

Can I make the cookies gluten-free?

I haven’t tried it but in theory, you can use gluten-free flour blend or almond flour instead of all-purpose flour to make the cookies without gluten. Remember that the texture and taste might be a little different, but they should still be very tasty

My cookies turned out too flat. What did I do wrong?

Flat cookies can happen for a few reasons. First, make sure your butter is soft but not melted because really soft butter can make the cookies spread too much. Also, make sure you have enough flour to give your food a solid form. Putting the dough in the fridge before baking can also stop it from spreading too much.
