- Irish cream flavor: The Irish cream adds subtle richness rather than strong alcohol flavor. For a non-alcoholic option, Irish cream coffee creamer works beautifully.
- Espresso balance: Espresso powder deepens the chocolate flavor without making the cookies taste bitter or overly “coffee-forward.”
- Chill for thickness: Chilling the dough helps prevent spreading and creates thicker, bakery-style cookies with soft centers.
- Chocolate distribution: Use a mix of chunks and chips for pockets of melted chocolate and balanced texture throughout.
- Don’t overbake: Cookies should look slightly underdone in the center when removed from the oven—they will set as they cool.
- Salt finish: A light sprinkle of flaky sea salt enhances the espresso and chocolate flavors.
- Storage: Store cookies in an airtight container at room temperature for up to 3 days or freeze baked cookies for up to 2 months.
- Make ahead: Dough can be refrigerated up to 48 hours for even better flavor development.
