1️⃣ Preheat & Prep: Preheat oven to 350°F (175°C). Line a baking sheet with parchment paper.
2️⃣ Mix Dry Ingredients: Whisk together flour, cocoa powder, baking soda, salt, and espresso powder in a bowl.
3️⃣ Cream Butter & Sugar: In another bowl, beat butter, brown sugar, and granulated sugar until fluffy. Add eggs, vanilla, and peppermint extract; mix well.
4️⃣ Combine & Add Mix-ins: Gradually add dry ingredients to wet, mixing until just combined. Fold in chocolate chips and crushed candy canes.
5️⃣ Scoop & Bake: Scoop dough balls (about 1.5 tablespoons each) onto baking sheet. Bake for 9-11 minutes, until edges are set but centers remain soft.
6️⃣ Cool & Serve: Let cookies cool on the baking sheet for 5 minutes, then transfer to a wire rack.
Notes
✔ For chewier cookies, chill the dough for 30 minutes before baking. ✔ Use Dutch-process cocoa for a richer flavor. ✔ Substitute almond flour for a gluten-free version. ✔ Add a white chocolate drizzle for extra holiday flair!
