I’m a seasonally confused person. I bake pumpkin muffins in August, wear scarves in May, live in my Uggs, and Christmas shop in my flip flops. To me, flavors (and apparently shoes) know no seasons.

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.

I precisely followed the recipe.  While it’s not complicated by any means, it does require 4 separate bowls for different ingredients as you are preparing the dough.  Completely worth the extra dishes if you ask me.

I added an extra tablespoon of flour to the recipe because the dough was too sticky to handle.  I also added a handful of semi-sweet chocolate chips and crushed York Peppermint Patties.   A last minute, but totally necessary addition.

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.  Exactly how I like my cookies. 😉

Break out your Thanksgiving fat pants a little early this year!

York Peppermint Patty Fudge Cookies

Yield: 2 dozen cookies

Print Recipe

Super fudgy brownie cookies filled with York Peppermint Patties.


  • 1 cup + 1 Tablespoon (133g) all-purpose flour
  • 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 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


Sift together flour, cocoa powder, baking powder and salt in a medium bowl. Set aside.

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.

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.

Preheat oven to 350F degrees. 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.

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.

    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!

    When I came across this post, your cookies and photography were enough to make me want to jump through the screen and find my happy place. I figured me baking them myself would be more appropriate though :-)
    OH my goodness they have been my favorite cookie since! Your blog has been such an inspiration for me to set up my own and your recipes never disappoint.
    I felt it necessary to spread the word about this cookie and included it in my post with a link back to your page.

    Thank you so much and look forward to more addicting recipes from you.

    Hi Sally, I made these cookies and they are probably they best cookies I have tried! I was thinking of how to make this cookie base in a white chocolate version, but am having trouble thinking of what to substitute for the cocoa powder. Any suggestions? Thank you!

    Hi there,

    I made these today and I really really liked them, but found them a tad dry/chalky…….however I did not use a mixer as I don’t have one, and did these by hand, but really really worked my whisk to get everything creamy! Do others find that adding a tad more butter would help or maybe another egg?
    Thanks for your help!

    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!]

    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!
