Method
- Whisk the flour, baking soda, cornstarch, and salt together in a medium bowl. Set aside.
- In the bowl of a stand mixer fitted with a paddle attachment, cream the softened butter, brown sugar, and granulated sugar together on medium speed for 2-3 minutes, until light and fluffy.
- Scrape down the bowl. Add the whole egg and mix until just combined.
- Add the egg yolk, vanilla extract, and ¼ cup of Baileys Irish Cream. Mix until combined (the mixture may look slightly curdled).
- With the mixer on low speed, gradually add the dry ingredients, mixing just until no dry streaks remain.
- Using a rubber spatula, fold in the chocolate chunks until evenly distributed. The dough will be soft and sticky.
- Cover the dough tightly and refrigerate for at least 2 hours, or ideally overnight.
- When ready to bake, preheat oven to 350°F (175°C). Line baking sheets with parchment paper.
- Portion the dough into 1.5-tablespoon balls, roll them smooth, and place them 2 inches apart on the prepared sheets. Press a few extra chocolate chunks on top if desired.
- Bake for 10-12 minutes, until the edges are set and lightly golden but the centers are still soft.
- Let the cookies cool on the baking sheet for 5 minutes before transferring them to a wire rack to cool completely.
- For the optional glaze: Whisk the sifted confectioners' sugar, a pinch of salt, and 1.5 tablespoons of Baileys in a small bowl. Add more Baileys a few drops at a time until a thick but pourable consistency is reached. Drizzle over the cooled cookies.
Notes
Chilling the dough is essential to prevent excessive spreading and to develop flavor. If the dough is too soft after chilling, refrigerate it for another 30 minutes. For a nutty variation, replace half the chocolate chunks with toasted pecans or walnuts. Store glazed cookies in an airtight container at room temperature for up to 5 days. Un-glazed baked cookies freeze well for up to 3 months; add fresh glaze after thawing. Dough balls can be frozen and baked from frozen, adding 1-2 minutes to the bake time.
