How to Make Peanut Butter Cup Cookie Bars 

  1. Preheat the oven to 350°F and line a 13×18 sheet pan with parchment paper, spraying the parchment with non-stick cooking spray. Set aside.
  2. In a large bowl, using an electric mixer at medium speed, beat together the butter, peanut butter and sugars about 2 minutes and is smooth.
  3. Add the eggs and vanilla and mix on low speed until mixed in.
  4. Add the flour, baking soda and salt into the wet mixture and mix together until just incorporated. Do not keep mixing – do not overmix.
  5. Add chocolate chips in and stir with a wooden spoon, again no over-mixing, just until incorporated.
  6. Spread thick cookie dough out evenly. It helps to spray a rubber spatula with non-stick spray for spreading and dough will spread out so you don’t have to get the corners and edges perfect on the ends. .Sprinkle the Reese’s Cups onto the cookie dough and press into the dough lightly.
  7. Bake for 20 minutes or until golden brown. Add the Reese’s Pieces and ½ cup milk chocolate chips to the top and put in oven for 2 minutes, do not overbake so you get yummy, chewy bars.
  8. Cool in pan on wire rack. Makes 3-4 dozen bars depending how big you cut them.
  9. Woo-wee! Great with a glass of milk or a scoop of ice cream on top!

Other Pan Options for Thicker Bars

For thicker bars, bake in a 9×13 baking pan and bake 12-20 minutes longer.

Freeze Peanut Butter Cup Cookie Bars

  • You can also freeze these and pull them out when needed for parties or keep them in the freeze and pull out what you need when you are craving peanut butter stuffed cookies! 
  • Just layer the cookies in an airtight, freezer-safe container or ziploc, placing parchment paper between each layer.  To thaw frozen cookie bars, place the container at room temperature for 3-4 hours or overnight!

If you have a large group gathering, these cookie bars are perfect for a Halloween party, family gatherings, bake sales, potlucks, birthday parties or any kind of celebration!

  1. Wow! Really lovely cookie bars! For some reason I wasn’t expecting to like these – but I LOVE them, and so do my children & grandchildren! I didn’t have either the mini p b cups or Reese’s pieces on hand, so used both milk & semisweet morsels in dough and sprinkled mini m&m’s over the top. Other than those substitutions, I followed the recipe exactly. The texture is great and the flavor wonderful! Thanks for sharing. After my next shopping trip I’ll bake this as written.

  2. It is cookie season, so you will see more, plus I have tons on the blog. Cookies make the world go round! Thank you so much for your lovely comment Nehal! xo

  3. Really the cute one. I have tried these pretty peanuts cookies at home and the outcome was so gorgeous. Thanks for sharing this beautiful recipe with us. I hope you will share more cookie recipes in the future. Much love and regards. xoxo

  4. Oh my gosh! I think I have been waiting for a recipe like this my whole life and didn’t even know it! I need to get some of those candies and give this a whirl!

  5. Hey Holly, updated, thanks for catching that! Originally I had the dry ingredients in one bowl and then started with ‘another bowl’, but the dry ingredients do not have to be in a separate bowl to begin with. Updated the peanut butter to be added in with the unsalted butter. 🙂 Hope you love it!! xo

  6. I think there’s a step missing. Instruction #2 says “in another bowl…”, where was the first bowl? And where do you put in the peanut butter? Is that incorporated in the “beat together the butter…”? Does that mean unsalted butter and peanut butter?

  7. Liz that is the worst feeling, not knowing when the kitchen will be done when you blog about baking, cooking and holidays! I hope it all goes well for you! I’ll stay tuned! 😀

  8. I need to come check that chocolate drawer :D. These cookie bars are yummy..Perfect pairing of chocolate and peanut butter! Making them in a sheet pan is so convenient.,Thanks for sharing Kim 🙂

  9. Yuuuuummm, I am drooling. I have a weakness for Reese’s Pieces + I’m afraid I would go through these delicious cookie bars in like two seconds, but i’m willing to take that risk! I hope you love your new kitchen, so glad you’re back!! 😀

  10. I think I need to buy some mini peanut butter cups for Halloween and set aside some to make these yummy bars! P.S. Congrats on getting back in your kitchen. I’m hoping our remodel doesn’t end up being at Christmas!

  11. It definitely has peanut butter cups! 3 different kinds Katherine! haha Yes, it feels complete having the kitchen back in order! Thank you!

  12. A 3-week kitchen remodel sounds like my nightmare! When I was moving a few months ago, there was a time when all my kitchen things were in boxes and I couldn’t make muffins when a craving hit and I about had a nervous breakdown. I’m so glad you’re baking again! These bars sound like the perfect way to re-enter that world 🙂

  13. The cookies are looking so tasty and delicious. I am a huge fan of chocolate and choco chips. I think very soon I m going to try this dish and have it with my family and friends. Especially my lil brother would love it totally. Thanks for sharing this recipe with us. Looking forward to more. Best Wishes and Regards.

  14. I might break into your house just to find that chocolate drawer. Mmm!! Especially if it contains peanut butter cups (my fave). These look amazing Kim!!!! They’d be very dangerous around my place. Also – congrats on having a kitchen back!!
