Ingredients
Method
Step-by-Step
- Whisk together the all-purpose flour, baking soda, fine salt, and instant espresso powder.
- Beat the softened butter, granulated sugar, and packed light brown sugar for 2–3 minutes, until light and creamy.
- Beat in the egg, vanilla extract, and Baileys Original Irish Cream until combined. The mixture may look slightly separated, which is fine.
- Gradually mix in the dry ingredients just until no flour streaks remain. Fold in the semisweet chocolate chips.
- Cover the dough and refrigerate for about 30 minutes. Chilling helps prevent excessive spreading.
- Heat the oven to 350°F (175°C) and line baking sheets with parchment paper.
- Scoop approximately 1½ tablespoons of dough per cookie, spacing portions about 2 inches apart on the prepared sheets.
- Bake for 10–12 minutes per batch, until the edges are set while the centers still look slightly soft.
- Cool the cookies on the baking sheet for 5 minutes, then transfer them to a wire rack to finish cooling.
Notes
Use instant espresso powder rather than brewed coffee so the dough gets a strong coffee flavor without extra liquid. Do not overbake; the centers finish setting as the cookies cool. Store airtight at room temperature for about 3–4 days. Unbaked dough can be refrigerated for up to 2 days or frozen in scoops for longer storage.
