Mint and chocolate are just plain meant to be and I’m not about to wait until Christmas to share these with you!

These sinfully rich and fudgy chocolate cookies are a chocoholics dream. While I continue to insist I am not a huge chocolate fan, anything chocolatey looking like this is simply irresistible.

My trusted friends over at Cooks Illustrated have a proven chewy and thick chocolate fudge cookie recipe. The recipe is pretty basic and comparable to a brownie recipe. Melted chocolate, butter, eggs, sugar, and cocoa powder. They add a little baking powder to give the cookies some lift and brown sugar to keep the cookies soft.

Rather than mixing the peppermint patties directly into the dough, I pressed pieces on top of the cookies after I rolled them on a cookie sheet.

If the peppermint patties were rolled onto the bottom of the cookie, the peppermint patty goo would inevitably melt first and spread – preventing the cookie dough from baking evenly. You want the goo to melt on top, not underneath the cookie. 😉

These cookies are like biting into a gooey brownie, soft cookie, and melted peppermint patty all at once. They’re sinfully rich, incredibly dense, and monster-thick. If you have peppermint patties left on your hands, give these peppermint patty cookie bars a try, too. They’re equally indulgent and delicious!

Description

Super fudgy brownie cookies filled with York Peppermint Patties.


Ingredients

Scale
  • 1 cup + 1 Tablespoon (133g) all-purpose flour (spoon & leveled)
  • 1/4 cup (21g) unsweetened cocoa powder
  • 1 teaspoon baking powder
  • 1/4 teaspoon salt
  • 8 ounces semi-sweet chocolate, chopped (I used 2 Ghirardelli chocolate bars)
  • 2 large eggs
  • 1 teaspoon pure vanilla extract
  • 5 Tablespoons (75g) unsalted butter, softened to room temperature
  • 3/4 cup (150g) packed light brown sugar
  • 1/4 cup (50g) granulated sugar
  • 1 cup (180g) semi-sweet chocolate chips
  • 14 snack size York Peppermint Patties, chopped

Instructions

  1. Sift together flour, cocoa powder, baking powder and salt in a medium bowl. Set aside.
  2. Melt the chocolate in the microwave for about 1 minute. Stir. Continue to melt in 30 second increments until fully melted and smooth. Set aside. In a small bowl, whisk the eggs and vanilla. Set aside.
  3. With an electric or stand mixer with paddle attachment on medium speed, beat the butter until smooth and creamy – about 1 minute. Beat in the sugars, scraping down the sides every 10 seconds or so. The mixture will be granular. Mix in the beaten egg/vanilla until incorporated. Add the chocolate in a steady stream and beat until combined. Add the dry ingredients on slow speed. Fold in the chocolate chips. Do not overmix at any point in this process. Chill dough for at least 30 minutes.
  4. Preheat oven to 350°F (177°C). Scoop about 2 Tablespoons of dough and roll into a ball. Press a few pieces of peppermint patties on the tops of each cookie ball. Bake for about 10 minutes, or until the cookies have just begun to set with the centers still appearing very soft. They will firm up as they cool.
  5. Allow cookies to cool on baking sheet for at least 5 minutes before transferring to a wire rack to cool completely. Cookies stay fresh covered at room temperature for 5 days.

Reader Questions and Reviews

  1. Sally
    OMG these peppermint pattie brownie cookies are RIDICULOUS!!! Mine came out looking just as beautiful as they are in your pictures…im so proud of myself 😀 Couldnt eat more than 2 in one sitting though, because they are so rich and. I seperated the dough and baked half. Will bake the other half tomorrow for fresh out of the oven chocolately bliss!!! Just a Top Notch recipe! Thanks for posting!

  2. I have to chuckle at “snack-sized” York Peppermint Patties – are the bigger ones “meal sized”? These sound wonderful.

    1. haha! snack-size/fun-sized. Not the giant ones that are sold individually. Thank you Kay!

    1. chill covered for up to four days before baking them. Let sit out at room temperature for about 10 minutes so the dough is easy to handle. Thanks!

  3. Hi Sally,
    I have been trying to find the snack size pattys, but could only find the regular size ones at Safeway and Target. Should I just use half of one for each cookie? Or more/less? Thanks!

    1. Yes, the regular sized ones will work just fine. half of one for each would be perfect. Enjoy!

  4. Hi, loved these cookies…just wondering if I can roll into balls and freeze, then bake at a later time?? Thanks, Kathy

    1. Hi Kathy! You sure can. The dough balls may be frozen up to 3 months.

  5. First time on your website…found it while searching for a new cookie to take to our annual cookie exchange. This was the one! I baked 4 batches and I’m certain they will be a hit! They look wonderful and they are delicious…the perfect combo! And my husband couldn’t stop “sampling” them. 🙂 Thank you…I definitely will be trying more of your recipes.

    1. Hi Brenda! Welcome. I’m so happy you found my blog. I adore these cookies and my fiancé often requests I make them again. There are many “taste tests” for me too. Love peppermint patties! Hope they’re a hit at the exchange.

  6. These cookies are seriously TO.DIE.FOR. Made them last weekend, and trying to keep it to one a day (I froze most of mine) and it’s very hard! I used After Eights, because that’s what I had in the house, leftover from Christmas. Can’t get enough of them. Another fantastic recipe Sally!

  7. I made these yesterday as a gift for a friend who loves York Peppermint Patties. Needless to say, these were a hit. SO GOOD! Thanks for sharing.

  8. Not a fan of Peppermint Patties, but, these cookies made me change my mind! I made them for a Christmas party and decided to try one before bringing them along… Two cookies later, I was glad the recipe yield is 2 dozen. 😉 {Especially because no cookies returned home!]

  9. I made these yesterday, only 2 left. Was a bit worried about just how soft they were when taking them out. But they set so nicely and now they are super fudgey! Yum!

  10. I made these cookies for my son who’s a die hard York Peppermint Patties fan. My sister in law had made him cookies baked from a cake mix with patties in the center and while they are good, I wanted find a recipe made from scratch. I was so happy to find you had one! I stuffed the mini patties in the middle of the dough (used a little more than 2 tbs so the patty wouldn’t spill out) and they are absolutely amazing, soft, rich, fudgy with that surprise in the middle! My son thoroughly approved! I did have a little spillage from some of the cookies, but Most of them didn’t. I let them cool on the cookie sheet until they were set, and oh boy! They set into the most wonderful cookies! You never disappoint Sally!

  11. This recipe makes a delicious ugly sticky cookie. Most of them flattened out into a candy crust with some cookie spattered on top. I’m not a fan. I made a cookie last year where the dough surrounded the peppermint patties. I though that was much more successful. Thanks for sharing your recipe though.
