Thick, fudgy chocolate cookies loaded with chopped Andes mints and melty chocolate chips. Cool mint meets rich cocoa in every chewy bite—perfect for holidays, cookie swaps, or any mint-chocolate craving.
Preheat oven to 350°F. Line 2 baking sheets with parchment paper.
In a large bowl, beat softened butter, granulated sugar, and brown sugar until creamy and fluffy, about 2 minutes.
Beat in eggs one at a time until well combined, then mix in vanilla and peppermint extract.
In a separate bowl whisk flour, cocoa powder, baking soda, salt, and espresso powder (if using).
Add dry ingredients to the wet ingredients and mix on low just until no dry streaks remain; do not overmix.
Fold in chopped Andes mints and chocolate chips. If dough feels sticky, chill for 10 to 15 minutes.
Scoop about 1.5 tablespoons of dough per cookie onto prepared sheets, spacing 2 inches apart.
Bake 8 to 10 minutes, until edges are set and tops are slightly cracked but centers are soft.
Cool on the sheet for 5 minutes, then transfer to a rack. Press a few extra chopped mints on top while warm for a melty finish.
Notes
Store in an airtight container at room temperature for up to 4 days or freeze up to 2 months. For extra mint, drizzle with melted Andes mints once cooled. If using mint extract, start with 0.25 teaspoon and adjust to taste.
