The cookie is crumbly and tender, and the dulce de leche intense and sticky. Milk might be tempted to have a new favorite cookie.
Recipe can be doubled; if doing so, in Step 4 divide dough in two, then wrap in plastic and proceed with recipe.

Filled sandwich cookies may be stored in an airtight container for up to 3 days.
