This batch of White Chocolate Peppermint Cookies has become my holiday handshake: sweet, cool, and instantly recognizable. I discovered this combination on a snowy evening when I wanted something that tasted like the holidays but wasn't fussy. The first time I baked them, the whole house smelled like a candy shop — warm butter, toasted white chocolate, and bright peppermint — and my partner declared them an immediate tradition. They have crisp edges, a tender, chewy center, and those pockets of melted white chocolate that mingle with tiny shards of peppermint to give a perfect balance of sweet and refreshing sharpness. What makes these especially dear is how forgiving they are. The dough is easy to mix by hand or with a stand mixer, and the cookies hold up well for gift tins, cookie exchanges, or cozy evenings with hot cocoa. I often double the batch so there are extras for neighbors — the cookies travel well and keep their texture for a few days when stored properly. Over the years I've tweaked the sugar ratio and added a touch of cornstarch for that pillowy middle, and now this version is what everyone asks for when they see the holiday tin.

Ingredients

• All-purpose flour: 2 1/2 cups — I prefer King Arthur or another unbleached brand for consistent results; the protein content gives structure while keeping the cookies tender.
• Baking soda and salt: 1 teaspoon baking soda and 1/2 teaspoon fine salt to balance sweetness and provide lift; use fine salt so it dissolves evenly.
• Cornstarch: 1 tablespoon — a small addition that makes the centers soft and slightly cakey, ideal for a chewy texture.
• Unsalted butter: 1 cup (2 sticks) at room temperature — real butter gives the best flavor; if using salted, reduce added salt by about 1/4 teaspoon.
• Granulated sugar and light brown sugar: 3/4 cup granulated and 3/4 cup packed light brown sugar — the brown sugar adds moisture and depth while granulated sugar helps with crisp edges.
• Egg: 1 large at room temperature — eggs provide structure and help with the chewiness.
• Vanilla extract: 1 1/2 teaspoons — use pure vanilla for the cleanest, warm flavor.
• White chocolate chips or chopped bars: 1 1/2 cups — I use chopped high-quality white chocolate (Ghirardelli or Callebaut) for creamier pockets than standard chips.
• Crushed peppermint candy: 3/4 cup — crush candy canes or peppermint candies coarsely so you get crunch without turning everything chalky; reserve a tablespoon for sprinkling on top before baking.

Instructions

Step 1 — Preheat and prepare pans: Preheat the oven to 350°F (177°C). Line two baking sheets with parchment paper or a silicone mat. Using parchment prevents sticking and encourages even browning around the edges. Allow the butter to come to room temperature while you measure ingredients. Step 2 — Whisk dry ingredients: In a medium bowl whisk together 2 1/2 cups all-purpose flour, 1 teaspoon baking soda, 1/2 teaspoon fine salt, and 1 tablespoon cornstarch. Whisking ensures even distribution of leavening and prevents clumps that can cause uneven rise. Step 3 — Cream butter and sugars: In a stand mixer fitted with the paddle or in a large bowl with a hand mixer, cream 1 cup unsalted butter with 3/4 cup granulated sugar and 3/4 cup packed light brown sugar for about 2–3 minutes until light and fluffy. Scrape down the bowl and continue until you see pale ribbons; this traps air for a lighter texture. Step 4 — Add egg and vanilla: Beat in 1 large egg and 1 1/2 teaspoons vanilla extract until incorporated, about 30 seconds. Overbeating after adding the egg can thin the dough; mix just until combined. Step 5 — Combine wet and dry: Fold the dry mixture into the wet with a wooden spoon or low mixer speed until just combined; do not overmix. Look for streaks of flour to disappear but a slightly shaggy appearance — overmixing develops gluten and yields tougher cookies. Step 6 — Fold in mix-ins: Gently stir in 1 1/2 cups white chocolate (chips or chopped) and 3/4 cup coarsely crushed peppermint candy, reserving a tablespoon of crushed peppermint to press on top of each dough ball before baking. Folding gently keeps white chocolate pieces intact. Step 7 — Chill the dough (recommended): For best texture, chill the dough for at least 30 minutes or up to 48 hours. Chilling firms the fat so cookies spread less and develop deeper flavor through gentle enzymatic changes. Step 8 — Portion and bake: Use a 1 1/2 tablespoon cookie scoop to portion dough about 1 1/4 inches apart. Press a pinch of reserved peppermint onto each ball. Bake on the middle rack at 350°F for 9–11 minutes until edges are set and centers look slightly underbaked; they will finish while cooling. Rotate pans halfway through for even baking. Step 9 — Cool and finish: Let cookies rest on the baking sheet for 5 minutes, then transfer to a cooling rack. Allow at least 10 minutes for white chocolate to set; store cooled cookies in an airtight container layered with parchment for up to 4 days.

Storage Tips

To preserve texture, cool completely before storing. Layer cookies in an airtight container with parchment between layers to prevent sticking. At room temperature they keep up to 4 days; refrigerated they last about a week but may firm the white chocolate slightly. For longer storage, flash-freeze baked cookies on a sheet for 1 hour, then transfer to a freezer bag for up to 3 months. Reheat briefly in a 300°F oven for 4–6 minutes to refresh softness, or microwave single cookies for 10 seconds if you prefer gooey centers.

Ingredient Substitutions

If you prefer less sweetness, replace half of the white chocolate with semisweet chips for contrast; expect a slightly darker flavor. For a dairy-free option use vegan butter and dairy-free white chocolate; texture may be slightly different but still enjoyable. To make these gluten-free, swap to a 1-to-1 gluten-free flour blend and add 1/4 teaspoon xanthan gum if your blend lacks it — baking time should be similar. If you don't have cornstarch, substitute 1 tablespoon potato starch or omit it; the cookies will be a touch less tender.

Serving Suggestions

Serve warm with hot chocolate, strong coffee, or peppermint tea. For a festive platter, alternate these with dark chocolate crinkle cookies and ginger snaps. Garnish cookie boxes with ribbon and a small sprig of evergreen for holiday gifting. For an indulgent treat, sandwich two cookies with peppermint buttercream or a thin layer of softened peppermint ice cream for a seasonal ice cream sandwich.

Cultural Background

Cookies that combine chocolate and peppermint are a classic in American holiday baking, inspired by confections like peppermint bark and candy canes. The tradition of mint-flavored holiday treats dates back decades, with candy canes becoming a symbol of Christmas gatherings. This version merges the creamy profile of white chocolate — popularized in the mid-20th century — with the crisp, cooling bite of peppermint, creating a modern classic that nods to both nostalgia and contemporary baking trends.

Seasonal Adaptations

In winter, increase crushed peppermint for a bolder minty note and press small candy cane pieces on top for visual appeal. For spring or summer, omit peppermint and fold in chopped white chocolate and toasted almonds or substitute lemon zest for a bright twist. For Halloween, replace peppermint with orange-flavored candy pieces and add black cocoa for dramatic color. The base dough is versatile — a minor swap changes the theme while keeping the same texture you love.

Meal Prep Tips

Make dough ahead and portion into cookie-sized balls on a baking sheet, then freeze. Once solid, store balls in a freezer bag so you can bake fresh cookies from frozen; add 1–2 minutes to baking time. For busy holiday schedules, freeze baked cookies for last-minute entertaining. Label bags with date and bake time so you remember the details later. Use an ice cream scoop for consistent cookies, which helps predict bake times precisely when you prepare multiple trays at once.

These cookies are a small, joyful ritual — they make cold evenings cozier and holiday gatherings sweeter. I hope you make them your own, tweak a little here and there, and create the same warm memories we've cherished for years.
