Tiramisu Cookies are my favorite way to serve tiramisu flavors without spending hours in the kitchen. The espresso powder bakes into soft, buttery dough, and the mascarpone cream on top stays smooth and rich with a dusting of cocoa. I make them for Christmas parties, holiday cookie exchanges, and potluck gatherings because they're easier to transport and serve than traditional tiramisu. Unfilled cookies stay fresh at room temperature for 2 to 3 days or freeze for up to 3 months.
