BEST Thick Peanut Butter Cookies

Sometimes there’s nothing better than the classics, and one of my favorite classic cookies is peanut butter cookies. Well, I should clarify – these are giant peanut butter cookies because giant is so good, especially when we’re talking about cookies.

  • They are thick, chewy, and all about the peanut butter. It’s like a classic peanut butter cookie on steroids – extra big and filled with Reese’s Peanut Butter Chips.
  • These are easy peanut butter cookies, and each one is made with a whopping quarter cup of dough.
  • These giant peanut butter cookies are also freezer-friendly, which is what I usually do. I’ll make a batch, freeze them, and then pull them out whenever the peanut butter craving hits. They are so good!

Ingredients in GIANT Peanut Butter Cookies

Butter: Softened unsalted butter is the norm for cookies

Peanut Butter: You can use creamy or chunky but don’t use one you have to stir.

Sugar: Brown sugar and granulated sugar make these sweet and perfect.

Large Eggs: The standard size to buy!

Vanilla: For flavor

Milk: My secret peanut butter cookie ingredient!

Salt, Baking Soda, All-Purpose Flour: Typical for cookies. Be sure to measure your flour correctly.

Reese’s Peanut Butter Chips and/or Chopped Peanuts: These mix-ins take the cookies to the next level!

How to Make Thick Peanut Butter Cookies

  1. Cream: Cream the butter, peanut butter, and both kinds of sugar in a stand mixer or with a hand mixer.
  2. Mix: Add the eggs, vanilla, milk, baking soda, and salt and mix until well combined. Slowly add the flour and mix just until the dough comes together.
  3. Additions: Stir in the peanut butter chips and peanuts. 
  4. Scoop: To make the cookie dough balls, scoop a ¼ cup of dough and place them on prepared baking sheets. Then, press each one down with a fork to create the criss-cross mark on each cookie.
  5. Bake: Bake the cookies for 15 to 18 minutes at 350°F or until the bottoms are lightly golden and the cookies are no longer glossy. Cool them for about five minutes on the pan before removing them.

Tips for Easy Big Peanut Butter Cookies

  • Not into thick peanut butter cookies? You can make these smaller! Just scoop one or two tablespoons of dough and bake them for about seven to ten minutes.
  • If you opt for smaller cookies, you can cut the recipe in half, so you don’t get as many. Or, feel free to double the recipe if you want more.
  • Because they don’t spread much, it’s important to use a fork to press them down before you bake them.
  • For the best cookies, don’t overbake them. Once they have lost the glossy sheen, take them out of the oven.
  • Store the cooled cookies in an airtight container at room temperature. They will keep for up to three days. Or you can freeze them for up to a month.
  • Feel like dressing them up? Feel free to add some chocolate chips or different kinds of nuts.

How do you make thick cookies?

For this recipe, I use more brown sugar than granulated sugar, which helps make them nice and thick. They’re also made with double the amount of dough. Usually, I scoop one to two tablespoons of dough to make cookies – for large, thick peanut butter cookies, I use ¼ cup of dough for each one.

Do you need to chill cookie dough?

For this thick peanut butter cookie recipe, you don’t!

How do you make the criss-cross marks on peanut butter cookies?

Use the tines of a fork and press down on the dough. Then, turn the fork to create marks going the other way, so it looks like a hash mark.

How long do you bake giant peanut butter cookies?

Bake large peanut butter cookies for 15 to 18 minutes. They are done when they lose the glossy sheen on top.

How to store large peanut butter cookies?

Store them in an airtight container for up to three days at room temperature.

Can you freeze them? 

Yes, the baked cookies freeze great. Once they are cooled, store them in a freezer bag, and they will keep well in the freezer for a month.

These are the perfect cookies for the peanut butter fans in your life! Make a batch of these Bakery-Style Peanut Butter Cookies, and you’ll see – everyone will beg you for the recipe. Enjoy!

  1. TIP:Use an icecream scoop (same size as 1/4 cup) lightly sprayed with Pam and flatten against side of bowl. These were AMAZING!! I was a baker for many years, and these beat my cookies by far!!
