    Peanut Butter Cup Cookie Bars

    I'm finally back to baking!  Yee-haww!  We've been in the middle of a kitchen remodel and it's been the longest 3 weeks ever!  I was going nuts not being able to bake! UGH!  Talk about torture!

    Baking is kind of my sanctuary, happy place and I finally have my kitchen back! 

    So, without further ado, guess what I made first?  I had a major craving for chocolate and peanut butter!  So, I whipped up these easy Sheet Pan Perfect Peanut Butter Cup Cookie Bars first!  Yum!!

    Sheet Pan Perfect Peanut Butter Cup Cookie Bars

    • It's a certain shortcut to quick scrumptious peanut butter cookie bars when you have a crowd to feed!
    • You won't have to bake numerous batches of cookies, when you can easily press all the cookie dough into one pan and bake away!
    • Party-inspired treats for any occasion or celebration!
    • Cut them to the size preferred and you've got lots of treats!  We love that it's a great time saver in the kitchen!
    • Don't want full sheet sized bars?  It's quite alright!  Halve the recipe for a 9x13 pan!

    Sheet Pan Perfect Peanut Butter Cup Cookie Bars

    Ingredients You Need

    • all-purpose flour
    • baking soda
    • salt
    • peanut butter, creamy
    • unsalted butter, room temperature
    • light brown sugar
    • Zulka Sugar or granulated sugar
    • eggs
    • vanilla extract
    • Ghirardelli Milk Chocolate Chips
    • Reese's Mini Reese's Peanut Butter Cups

    Toppings

    • Reese's Pieces
    • Ghirardelli Milk Chocolate Chips

    How to Make Peanut Butter Cup Cookie Bars 

    1. Preheat the oven to 350°F and line a 13x18 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 9x13 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!

      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.

      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

    8. Holly Hocks says

      May 24, 2019 at 11:51 am

      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?

    9. Kim Lange says

      October 29, 2018 at 9:55 pm

      Awesome! These are perfect for that! Enjoy and thanks so much!

      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 🙂

    31. Supriya Kuttty says

      October 09, 2017 at 2:51 am

      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.

      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!!
