Ingredients
Scale
- 3/4 cup (170 g) unsalted butter, at cool room temperature
- 3/4 cup (150 g) packed dark brown sugar
- 1/2 cup (100 g) granulated sugar
- 1 tablespoon instant espresso powder
- 1 large egg, at room temperature
- 1 large egg yolk, at room temperature
- 2 teaspoons vanilla extract
- 3/4 teaspoon peppermint extract
- 1 3/4 cups (220 g) all purpose flour
- 2/3 cup (60 g) Dutch process cocoa powder
- 1 tablespoon cornstarch
- 1 teaspoon baking soda
- 1/2 teaspoon fine salt
- 1 cup (170 g) semisweet chocolate chips
- 4 ounces (115 g) white chocolate, chopped, for the stripes
- 1/3 cup (55 g) crushed candy canes, for topping
Instructions
- Beat the butter, brown sugar, granulated sugar and instant espresso powder for 2 to 3 minutes, until lighter in color and fluffy. Scrape the bowl once so no plain butter stays at the bottom.
- Beat in the egg, then the egg yolk, mixing until each is absorbed. Add the vanilla and peppermint extracts and mix until the dough looks smooth and glossy.
- Whisk the flour, cocoa powder, cornstarch, baking soda and salt in a separate bowl until the mixture is one even dark color.
- Add the dry ingredients to the butter mixture in two additions. Mix on low only until no flour or cocoa streaks remain. The dough will be thick and sticky.
- Fold in the semisweet chocolate chips with a spatula, reaching to the bottom of the bowl so the chips are evenly distributed.
- Cover and refrigerate the dough for at least 2 hours and up to 48 hours. This rest hydrates the cocoa and flour and firms the butter for thick cookies.
- Heat the oven to 350°F (175°C). Line two baking sheets with parchment. Let very cold dough stand at room temperature for 10 minutes so it can be scooped cleanly.
- Scoop 2 tablespoon portions and roll them into balls. Place them 2 inches apart on the prepared sheets, keeping the remaining dough refrigerated between batches.
- Bake one sheet at a time for 10 to 12 minutes, until the edges look set and the centers still appear slightly soft and puffed.
- Cool on the baking sheet for 10 minutes. The centers will finish setting as they cool. Move the cookies to a wire rack and cool completely before decorating.
- Melt the white chocolate gently in short microwave bursts, stirring between each. Drizzle thin stripes over the cold cookies and sprinkle immediately with crushed candy cane.
- Let the topping set for 30 minutes at room temperature before stacking or boxing the cookies.
