Ultimate Peanut Butter Cookies

If you like peanut butter, you are in for a real treat because today I am sharing the Ultimate Peanut Butter Cookie recipe. Think peanut butter oatmeal cookies loaded with peanut butter chips, Reese’s Pieces candies, AND chopped up Reese’s peanut butter cups. Oh, yes, these cookies are peanut butter heaven!

Peanut Butter Cookies with candy

Bring on the Candy!

I love going down the candy aisle at Smith’s to check out all of the latest and greatest candy selections, especially during Halloween time because they always have a huge selection to choose from. I stock up on candy for trick or treaters and for ME! I am too old to go trick or treating, but I am not too old to enjoy a treat!

I like to use the candy to make cookies. Two sweets are always better than one:) Plus, the candy makes the cookies super festive. These are the perfect cookies for Halloween, fall, or really anytime. If you are craving peanut butter, these cookies will for sure cure your craving!

Ultimate Peanut Butter Cookie Recipe

Who’s ready to get baking? My hand is raised! Here are a few tips to guarantee your cookies turn out perfect every single time!

  • Use old fashioned oats, not quick oats.
  • Make sure your butter is at room temperature, but NOT melted or too soft. If your butter is too soft, your cookies will spread out.
  • Use regular creamy peanut butter, not natural peanut butter. I used Kroger brand, it’s always a great price!
  • Cream the butter, sugars, and peanut butter together until smooth. I like to use a stand mixer, but a hand held mixer works great too!
  • When you add the dry ingredients, mix on low until just combined. Don’t over mix.
  • Stir in the peanut butter chips (you can find these in the baking aisle by the chocolate chips at your Kroger store), Reese’s Pieces, and chopped up peanut butter cups.
  • Bake the cookies for 10-12 minutes, or until they are lightly browned around the edges, but still soft in the middle. Don’t over bake.
  • Pretty tip! When the cookies come out of the oven, you can gently press additional Reese’s Pieces and chopped peanut butter cups on top of the cookies to make them extra pretty. This step is optional, but I always do this:) I also add a little sprinkling of flaky sea salt.
Loaded Peanut Butter Cookies

The peanut butter oatmeal cookies are soft, chewy, and LOADED with peanut butter goodness. I love all of the different textures going on…crisp and crunchy Reese’s Pieces, melty peanut butter cups, and peanut butter explosion from the peanut butter chips!

Peanut butter perfection indeed! These really are the ultimate peanut butter cookies. Pro tip-have a glass of cold milk nearby! There is nothing better than cookies and milk!

  • Preheat the oven to 350 degrees Line two large baking sheet with Silpat baking mats or parchment paper. Set aside.
  • In a medium bowl, stir together the oats, flour, baking soda, and salt. Set aside.
  • Using a stand mixer or hand held mixer, beat the butter, peanut butter, and sugars together until creamy and smooth, on medium speed. Scrape down the sides of the bowl with a spatula, if necessary. Beat in the egg and vanilla extract. Mix until well combined.
  • Add in the dry ingredients and mix on low until just until the combined. Don't over mix. Gently stir in the peanut butter chips, Reese's Pieces, and chopped peanut butter cups.
  • Scoop the cookies into round balls, about 2 tablespoons of dough per cookie, and place on the prepared baking sheets, leaving 2 inches in between cookies. Bake for 10-12 minutes, or until the cookies are lightly browned around the edges, but still soft in the middle.
  • Remove cookies from oven and sprinkle the cookies with sea salt. You can also gently press additional chips, candies, and peanut butter cups on top of the cookies to make them look extra pretty. Let the cookies cool on the baking sheet for about 5 minutes or until set. When set, transfer cookies to a wire rack and cool completely.


You can gently press additional Reese’s Pieces candies and chopped peanut butter cups on top of the cookies right after they come out of the oven to make them extra pretty. That is what I do:)

  1. I have been adding PB chips, Reese’s pieces and chopped PB cups to your soft peanut butter cookie recipe since I started making it years ago! Soooo good!

  2. 5 stars
    These cookies were very good and full of peanut butter goodness! I think next time I won’t leave them in for the full 12 min. They were a little crispier, but still delicious.

  3. My Reese’s loving boys would love these! Can’t wait to try! I’m wondering how the Trader Joe’s mini peanut cups would work instead of chopping Reece cups ! I’d love to know if anyone has tried them!

  4. My cookies came out dry and crumbled while eating them. I followed the directions exactly, except used natural peanut butter because that’s all I had. I wonder if that’s what caused it.

  5. Can I make these without the rolled oats and they will still come out fine? Also most peanut butter chocolate candy cookie recipies require refrigeration does this one not need to bc it has peanut butter?

  6. 5 stars
    These are incredible if you love peanut butter like I do! They’ve become part of my Christmas baking the last few years – I have to keep them as a treat – if I make them, I will eat them all!

  7. 5 stars
    Another great recipe by Maria! I took a gamble and doubled the recipe, and I’m so glad I did. These were the perfect texture. I don’t like when my cookies are too overloaded with mix-ins, so I doubled everything EXCEPT the chocolate chips, etc. So excited to share with a friend who loves Reese’s Pieces! Thank you, Maria! Love your sweet AND savory recipes!
