I have to say, I’m a softy for a REALLY good cookie. (Think, an ooey gooey Peanut Butter Oatmeal Chocolate Chip Cookies Recipe!)

I used to tease my husband and call him a cookie monster as he’d eat every cookie in sight. Turns out, age is making me the same way!

I love when there’s a delicious cookie in front of me. And I’m not entirely fussy on the kind but do have a few faves. One of which I’m sharing today!

Peanut Butter Oatmeal Chocolate Chip Cookies Recipe {Outrageously Delicious + Secret Tips!}

Outrageously Delicious Cookie Combination

My soft spot especially lands with the Peanut Butter Oatmeal Chocolate Chip options. There’s something about that triple combination that makes them unbeatable.

I could eat these cookies every single week! Pour a big glass of milk and it makes the perfect bedtime snack!

Big Fat Cookies – Secret Tips

If you have envy over those photos of the perfect cookies, look no further. I have a secret tip for you. Well, actually a couple.

First off, be sure to follow the recipe closely. Pay attention to details like mixing times.
The second tip is to make sure you refrigerate this dough as instructed.
Thirdly, don’t overbake unless you’re looking for a crispy cookie! Once the edges are slightly brown, get them out and let them finish baking on the pan for 5 additional minutes.
Those 5 minutes of ‘baking/cooling’ time on the pan are important. Please don’t skip!
Finally, once the cookies come out of the oven, gently press a couple of additional chocolate chips on top. This gives the perfect finishing touch for a magazine-worthy cookie!

Prep Time: 15

Cook Time: 10

Additional Time: 20

Total Time: 45

Servings: cookies

Ingredients

1 1/2 cups all purpose flour
1 teaspoon baking soda
3/4 teaspoon sea salt
1 teaspoon baking powder
2 sticks room temperature butter
1 cup sugar
1/2 cup brown sugar light or dark will work
2 large eggs room temperature
1 cup creamy peanut butter
2 teaspoons vanilla extract
2 cups old-fashioned oats
2 1/2 cups chocolate chips + additional for topping

Instructions

Whisk flour, baking soda, baking powder, and sea salt into a medium sized mixing bowl. Set aside.
In a large mixing bowl (I prefer a stand mixer), beat butter until smooth. Minimum of 1 minute.
Add the white and brown sugars. Beat for 2 additional minutes.
Then add eggs, peanut butter, and vanilla. Continue beating for 1 minute, scraping sides when necessary.
Add the dry ingredients you had mixed in step 1 into the stand mixer bowl. Gently combine on low.
Then add the oats and continue mixing until those are combined as well.
Finally add the chocolate chips and mix for an additional minute.
Cover the bowl and chill dough in refrigerator for 20 minutes.
Preheat oven to 350 degrees. (If convection oven, drop to 325 degrees.)
Line your baking sheet with a silicone baking mat or parchment paper.
Place large tablespoons of cookie dough onto pan, about 2 1/2 inches apart.
Bake for 10-12 minutes or until the edges are slightly brown.
Remove from oven and gently top each cookie with a couple additional chocolate chips.
Let cool on pan for 5 minutes.
Remove from pan and finish cooling on cooling racks.
Enjoy!

Notes

Once completely cool, store cookies in an air tight container.

Between baking batches, place the dough back in the refrigerator to keep it cool.

Let pans cool between batches too.

As always, if you know your oven bakes hotter or cooler, please adjust the baking temp accordingly. (The temp, not the time. Because you don’t want to rush the baking process as that’s part of the magic!)

Absolutely one of the best cookies I’ve made in my 70 years. I used half milk chocolate and half dark chocolate chips. Divine!

Can you add chopped walnuts? If so, how much do you suggest?

Hi Gail,

I have not with this recipe but I don't see why you couldn't! When I've added nuts to cookies, I tend to start with 1/2 cup. That usually gives me the consistency and flavor I'm looking for.

I followed the recipe exactly as I’m searching for the perfect oatmeal peanut butter chocolate chip cookie. The cookies are fabulous!!!! The specific mixing times/cook time/rest time were perfect, especially the 5min rest on the cookie sheet after taking out of the oven. I believe I have found my perfect cookie!!
