Peppermint Patty Surprise Chocolate Chunk Cookie Bars

Christmas is coming….and fast. I wish I could hit a pause button right now and soak up all of the festivities just a little longer.

I was like a giddy school girl when I cut into these bars last week. The gooey goodness coming out of them should be illegal, lol!

York Peppermint Patty’s are perfectly nestled in between two layers of buttery crisp yet perfectly chewy cookie dough layers for a thick knock out bar.

Run, don’t walk to your kitchen and get baking these monstrous treats. Enjoy!

Here is your line up of ingredients. Simple right?

Love these patties, especially around Christmas!

You know the drill, let’s start with the butter.

Add the sugar.

Add the egg, vanilla and mix, mix, mix ๐Ÿ™‚

Time for the dry ingredients.

Yay for chocolate chunks! Feel free to use regular chocolate chips if you’d rather.

Give her another quick mix and…..

Perfect-o! Now, sample this fabulous dough.

Take half of your dough and press it into the bottom of your prepared 8×8 inch baking pan.

Peppermint Patty time!

Layer the bag over the first layer of dough, then top with your remaining dough.

Press evenly.

Like so, now time to bake! 350 degrees F. for 40 minutes, until golden and baked through.

How pretty is that?

After I pulled the foil away, found this little fabulous corner. Yum!

The trick is, you MUST let these cool completely, which might seem like forever (about an hour). They have to finish setting up in the middle. Trust me, I was impatient ๐Ÿ™‚


Peppermint Patty Surprise Chocolate Chunk Cookie Bars

2 sticks unsalted butter, softened

3/4 cup granulated sugar

3/4 cup packed light brown sugar

2 large eggs

1 1/2 teaspoons pure vanilla extract

3 cups all purpose flour

1 teaspoon baking soda

3/4 teaspoon kosher salt

12 ounce bag chocolate chunks

12 ounce bag of York Peppermint Patties

1. Preheat oven to 350 degrees F. and line an 8×8 inch baking pan with foil that has been generously sprayed with cooking spray.

2. Place butter and sugars into the bowl of a stand or electric mixer. Beat until creamy and light. Add eggs and vanilla beating until well combined.

3. Place flour, baking soda and salt into a large bowl, mixing to combine then slowly add to wet ingredients. Add chocolate chunks and mix until just combined. Transfer half of dough into prepared baking pan, pressing evenly. Place unwrapped peppermint patties over first half of cookie dough. Place remaining half of cookie dough over peppermint patties, pressing to flatten dough. Bake for 38-45 minutes or until baked through. Be sure to Let the cookie bars cool completely before cutting into squares. Takes about an hour. Be patient, it is finishing setting up!!

4. Cut cooled bars into squares and serve.

Makes 12 bars

**Note: If you would like a thinner bar, use the same recipe plus one more bag of Peppermint Patties and arrange in a 9×13 inch baking dish. Watch baking time after 25-30 minutes in the larger pan. Enjoy!**


Have a great day and come back soon!

    Hello! I’d love to make these! A question: is the recipe correct in calling for two sticks of butter? It looks like you only used one in your pictures…

  2. llopez

    hi! I saw this just recently. I was wondering about the butter? In the picture about you only have one stick of butter divided into two. The recipe requires 2 sticks butter. Is that equivalent to 1 cup of butter, or do you mean 1/2 of butter divided into 2 (based on the picture above)? Thanks! ๐Ÿ™‚

    These look absolutely wonderful… and I be could be made with other types of candy for those who don’t like mint. I’m thinking Rolos, Milky Way, Mounds, etc.

    Made these the other night and they are delicious! I made mine in the 9×13 pan since I like a thinner bar but they were still pretty thick – goodness I have no idea how thick they’d be in the 8×8 : )

    Hi Jenny! I made these for my school’s front office staff, and they LOVED them. I heard through the grapevine that teachers were sneaking up into the front office to grab one for themselves. Thanks for posting! Merry Christmas!

  6. Hi Jenny! I wanted to let you know that I made these AMAZING cookie bars this weekend and brought them to a party. They disappeared and everyone raved about them. The gooey peppermint patties inside were delicious!!

  7. Abby

    I want to make these for my boyfriend & his father but neither are big fans of mint. Would I be able to switch out the York peppermint patties for another candy bar such as the cookies n’ creme?

    1. Abby

      wow thanks for getting back to me so quickly. I do have one other question though. Is it 2 sticks of butter? From the picture it looks like 1 stick sliced in half? Just want to double check, thanks!

  8. Sarah

    These are currently baking in my oven! ๐Ÿ˜€ I am so excited to try the goodness. I can’t eat too many though, i’m making them as a gift :/

  9. Kim

    I made these this week. It was a rotten Tuesday so I got everyone to bed and made them. I couldn’t try them until Wednesday morning. Amazing! Ummm… I had a dentist appointment Thursday and didn’t want to go too crazy, but it was REALLY hard to not eat them all! You totally ROCK!

  10. Emily

    i made these with my 5 year old daughter and they were amazing! we put them in a 9×13 and they turned out delicious! thanks for a great recipe!

  11. I like baked peppermint patty surprise chocolate chunk cookie bars.
    These look SO goodโ€ฆI make some from a Martha Stewart recipe, but these look much healthier!! Iโ€™m going to have to try them.Thanks for sharing!

    The recipe looked so amazing that I had to try it out. Peppermint and chocolate just screams holiday time for me! Cant wait to try them, they are in the oven now. ๐Ÿ™‚ Testing the recipe out for my husbands work Christmas party, I have a feeling they will be a big hit just from the pictures. Thanks so much for posting this!!

    Jenny – First, these look so yummy! I need to take a treat to a ward party this week so these just might need to make an appearance. But quick question. Is the cookie pretty crunchy from the long bake time? I like mine on the chewier side so I am wondering if I could shorten the cook time a little? What do you think?

    1. Hi Tricia,
      The cookie is buttery crisp on the top, but the inside is nice and chewy. I took mine out at about 35 minutes and they were perfect inside. Just make sure you give them a good hour before cutting into squares ๐Ÿ™‚

  14. Mmmm, I love that you made them so thick instead of having thinner bars. Oops, I typed brownies there first….freudian slip?…because they make me think they’d be sorta fudgy, chocolatey goodness in that thick of a bar. Yum.
