Dark chocolate linzer cookies with a hint of mocha and a luscious layer of creamy dulce de leche will dazzle at your next holiday celebration!
**Prep time includes making the dulce de leche.
Note that cookies come together quickly, but dulce de leche must simmer on the stovetop for 2-3 hours. Plan accordingly.
Cookies may be frozen before filling with dulce de leche.
Dough may be made in advance. Store tightly wrapped in the refrigerator.
