Fudgy White Chocolate Peppermint Cookies with Crushed Candy Canes

Rich, fudgy, and packed with sweet white chocolate chips and crunchy candy cane shards, these white chocolate peppermint cookies are the most festive centerpiece for holiday cookie tins.

Peppermint can easily overpower a delicate cookie dough, tasting more like toothpaste than gourmet chocolate. In our test kitchen, we balanced Dutch-processed dark cocoa with pure peppermint extract and pure vanilla, ensuring the deep chocolate fudginess shines through every bite.

Pressing extra white chocolate morsels and crushed candy canes into the tops of the hot cookies straight out of the oven ensures picture-perfect holiday cookies with a satisfying candy cane crunch.

Baking a dark chocolate cookie that stays as soft, dense, and chewy as a pan of fudge brownies—without needing to chill the dough—comes down to cocoa chemistry and starch modification. We use Dutch-process (alkalized) cocoa powder rather than natural cocoa powder because Dutch cocoa has been washed with a potassium carbonate solution that neutralizes its acidity, turning the powder jet-black and giving it a smooth, Oreo-like chocolate depth that pairs seamlessly with cool peppermint and creamy white chocolate.

To guarantee that the cookies never bake up dry or cakey, we use a 2-to-1 ratio of moisture-rich brown sugar to granulated sugar and whisk 1 teaspoon of pure cornstarch into the flour. Cornstarch softens the wheat gluten network inside the oven, allowing the cookies to puff up in 9 minutes and settle into crinkly, fudgy pillows that hold pressed white chocolate chips and ruby candy cane shards on top.

Key Ingredients (Overview)

• Dutch-Process Cocoa Powder: 1/2 cup (42g) gives these cookies a dark, velvety brownie flavor.
• All-Purpose Flour & Cornstarch: Cornstarch keeps the cookie centers soft and tender for days.
• Unsalted Butter: 1/2 cup (113g) softened to room temperature for classic buttery spread.
• Brown Sugar & Granulated Sugar: A 2:1 brown-to-white sugar ratio locks in chewy fudginess.
• Pure Peppermint Extract: 1/2 teaspoon gives the exact right balance of cool holiday mint.
• High-Quality White Chocolate Chips: 1 and 1/4 cups (225g) divided for folding and pressing on top.
• Crushed Candy Canes: 1/3 cup of peppermint candy shards for holiday crunch.

Start by Creaming the Butter, Sugars, and Peppermint

Beat softened butter, brown sugar, and granulated sugar for 2 minutes on medium speed until smooth and fluffy.

Beat in the egg, vanilla extract, and peppermint extract. Sift in the flour, cocoa powder, cornstarch, and baking soda, mixing on low speed just until a thick chocolate dough forms.

Reserve 1/4 cup of your white chocolate chips and all 1/3 cup of your crushed candy canes in two small bowls right next to the oven before your first tray finishes baking. Why? If you fold crushed candy canes directly into raw cookie dough before baking, the hard sugar candy melts into sticky red puddles against the hot parchment paper and turns chewy-hard on the teeth.

Pressing the crushed candy canes and extra white chocolate chips lightly into the tops of the cookies within 60 seconds of pulling the tray from the 350°F (177°C) oven lets the residual warmth of the chocolate dough glue every shard in place while keeping the candy canes crisp and jewel-bright.

Fold in 1 cup of white chocolate chips using a silicone spatula.

The Secret to Chewy Brownie Cookie Centers

Adding 1 teaspoon of cornstarch to the dry flour and cocoa mixture inhibits excess gluten development, guaranteeing that your chocolate cookies stay ultra-fudgy and bendable in the center rather than baking up dry or cakey.

How to Scoop, Bake, and Garnish the Cookies

Scoop 2-tablespoon mounds of dough onto parchment-lined baking sheets, spacing them 2 inches apart.

Bake at 350°F (177°C) for 9 to 11 minutes until the edges are just set and tops are crinkled.

Immediately press reserved white chocolate chips and crushed candy cane pieces into the soft tops of the hot cookies, then allow them to cool on the baking sheet for 10 minutes.

Common Mistakes to Avoid with White Chocolate Peppermint Cookies

• Mixing crushed candy canes into the raw dough before baking: Hard peppermint candies liquefy at 350°F in the oven, weeping sticky syrup onto the pan and losing their crunch. Always press crushed candy canes onto the warm cookies immediately after removing them from the oven.
• Using spearmint or imitation mint extract instead of pure peppermint extract: “Mint extract” at the grocery store is often a blend of spearmint and wintergreen, which tastes like chewing gum or toothpaste in chocolate dough. Make sure the bottle says 100% Pure Peppermint Extract—and measure exactly 1/2 teaspoon with a measuring spoon (never pour freehand over the bowl!).
• Overbaking dark chocolate cookies waiting for them to look brown: Because Dutch-process cocoa dough is already dark brown-black, you cannot see golden edges. Pull the baking sheet at 9 to 11 minutes when the outer rims feel set and the centers still look soft and slightly puffy—they firm up on the warm pan over the next 10 minutes.
• Using pulverized candy cane dust on top: Shake your crushed candy canes in a fine-mesh strainer for 5 seconds to sift out the fine pink powder, using only the crisp 1/8-inch ruby-and-white shards on top of the cookies.

Substitutions & Holiday Cookie Box Variations

• White Chocolate Dipped Half-Moon Peppermint Cookies: Instead of pressing candy canes across the whole top, let the baked chocolate-chip cookies cool completely, dip half of each cookie diagonally into melted white chocolate, and sprinkle the wet white chocolate half with crushed candy canes!
• Andes Peppermint Crunch or Ghirardelli Bark Chunks: Swap half of the white chocolate chips for chopped Andes Peppermint Crunch baking chips or chopped squares of Ghirardelli Peppermint Bark.
• Double Dark & White Chocolate Mint Cookies: Fold 1/2 cup of semi-sweet or 60% dark chocolate chunks alongside 3/4 cup of white chocolate chips into the dough for extra molten chocolate pockets.
• Espresso Peppermint Mocha Upgrade: Whisk 1 teaspoon of instant espresso powder into the creamed butter and sugars to amplify the deep Dutch cocoa flavor.

Storage, Gifting & Freezing Instructions

Room Temperature Storage: Once the cookies have cooled completely on a wire rack for 45 minutes, store them in an airtight container layered between sheets of parchment paper at cool room temperature for up to 7 days. Keep peppermint cookies in their own dedicated tin or container during holiday gifting, as cool peppermint aroma will infuse plain butter cookies stored in the same box!

Chilling Dough Ahead: While no chilling is required, you can scoop the dough balls up to 48 hours ahead and chill them covered in the refrigerator (let sit at room temperature for 15 minutes before baking).

Freezing Dough Balls or Baked Cookies: Freeze scooped dough balls (without candy canes) in a freezer zip-top bag for up to 3 months; bake straight from frozen at 350°F (177°C) for 11 to 12 minutes, then press the white chocolate chips and crushed candy canes on top right out of the oven!

Frequently Asked Questions

Can I use natural unsweetened cocoa powder if I don’t have Dutch-process?

Yes! Natural unsweetened cocoa powder works 1-for-1 in this recipe; the cookies will simply be a slightly lighter reddish-brown color with a classic brownie tang compared to the jet-black Oreo hue of Dutch-process cocoa.

How do I get perfectly round bakery-style cookies?

Right after pulling the baking sheet from the oven (and before pressing the candy canes on top), place a wide round biscuit cutter or the rim of a drinking glass upside down over each hot cookie and swirl it in a gentle circle for 2 seconds—that tucks any uneven edges into a flawless bakery circle!

Why did my candy cane pieces turn slightly sticky after 3 days?

Hard peppermint candy is hygroscopic and absorbs humidity in warm kitchens. Placing a dry paper towel inside the lid of your airtight cookie tin absorbs excess moisture and keeps the candy cane shards crunchy.

The Final Result

These cookies emerge thick, dark, and studded with glistening ruby and white holiday jewels.

The contrast between the soft chocolate truffle center, creamy melted white chocolate, and crisp candy cane crunch is pure holiday perfection.

Store in an airtight container at room temperature for up to 7 days, or freeze baked cookies for up to 3 months.
