These cookies are a sophisticated twist on a classic, where Irish cream liqueur adds a velvety texture and a hint of cocoa. They yield an incredibly soft, chewy crumb that stays moist for days, making them a perfect grown-up treat for celebrations or a simple coffee break.
For best results, use room temperature ingredients. Do not overmix the dough after adding flour. Cookies can be baked immediately or chilled for a thicker texture. Dough balls freeze well for up to 3 months; bake from frozen, adding 1-2 minutes.
