These Espresso Martini Cookies combine rich cocoa, bold espresso, and a hint of rum extract for a soft, decadent cookie with a cocktail-inspired personality. A dip in white chocolate and a coffee bean garnish give each cookie a polished finish that looks bakery-made.

Ingredients

Scale
  • 1 cup all-purpose flour, gluten-free if needed
  • 2/3 cup natural unsweetened cocoa powder
  • 2 tablespoons instant espresso powder
  • 1 teaspoon baking soda
  • 1/2 teaspoon kosher salt
  • 1/2 cup unsalted butter, at room temperature
  • 1/2 cup granulated sugar
  • 1/2 cup light brown sugar, packed
  • 1 large egg, at room temperature
  • 1 teaspoon vanilla extract
  • 1 1/2 teaspoons rum extract
  • 1 tablespoon milk
  • 10 to 12 ounces premium white chocolate
  • Coffee beans, for garnish

Instructions

  1. In a medium mixing bowl, whisk together the flour, cocoa powder, instant espresso powder, baking soda, and salt until everything is evenly combined. This ensures the coffee and chocolate flavors distribute evenly through the dough.
  2. In a separate large bowl, beat the butter, granulated sugar, and brown sugar with a hand mixer or stand mixer fitted with the paddle attachment. Mix on medium-high speed for 2 to 3 minutes, or until the mixture looks lighter in color and fluffy in texture.
  3. Add the egg, vanilla extract, rum extract, and milk. Continue mixing for 1 to 2 minutes, stopping to scrape down the sides and bottom of the bowl as needed. The mixture should look smooth, creamy, and well blended.
  4. Reduce the mixer speed to low. Gradually add the dry ingredients into the wet mixture and mix just until the dough comes together. Avoid overmixing so the cookies stay tender.
  5. Cover the bowl tightly with plastic wrap and chill the dough for at least 2 hours. For the best texture and flavor, chill it overnight. The dough can rest in the refrigerator for up to 3 days. Do not skip this step, because chilling helps prevent the cookies from spreading too much in the oven.
  6. When you are ready to bake, preheat the oven to 350°F. Line two large baking sheets with parchment paper. If the dough has chilled for longer than 24 hours, let it sit at room temperature for 15 to 30 minutes so it softens slightly and becomes easier to scoop.
  7. Scoop the dough using a medium cookie scoop, about 3 tablespoons per portion. Place each mound onto the prepared baking sheets, leaving 2 to 3 inches between them. The dough will feel sticky, so lightly damp hands can help if needed.
  8. Bake for 10 to 12 minutes, or until the edges are set and the tops still look slightly soft in the center. Do not overbake. These cookies finish setting as they cool, and that helps keep the texture soft and rich.
  9. Allow the cookies to rest on the baking sheet for 5 minutes, then transfer them to a wire rack to cool completely. Cooling fully is important before dipping, or the chocolate coating will not set properly.
  10. While the cookies cool, place the white chocolate in a microwave-safe bowl or tall measuring cup. Heat in 30-second intervals, stirring well after each round, until the chocolate is melted, smooth, and glossy. A taller container makes dipping easier and cleaner.
  11. Dip half of each cooled cookie into the melted white chocolate. Let the excess drip off, then place the cookies on parchment paper. Immediately top each cookie with 1 to 3 coffee beans before the chocolate begins to set.
  12. Let the chocolate harden at room temperature, or place the cookies in the freezer for a few minutes to speed things up. Once set, the cookies are ready to serve, package, or store.

Notes

  • Chilling matters: It keeps the cookies thick and helps the flavor deepen. Overnight chilling gives the best result.
  • Storage: Keep the finished cookies in an airtight container at room temperature for up to 4 days, or refrigerate them for up to 1 week.
  • Freezing: Freeze baked cookies in a single layer first, then transfer them to a freezer-safe container for up to 3 months. Thaw at room temperature before serving. You can also freeze the dough for up to 3 months and bake straight from frozen, adding a couple of minutes to the bake time.
