Warm up your can of whipped cream by immersing it in a pot filled with medium-hot water for three to five minutes. (Water should cover at least half of the can.)
Combine Malibu, creme de cacao and Tia Maria in an Old-Fashioned style glass. Stir gently. Remove whipped cream can from medium-hot water and top drink mixture with whipped cream. Drizzle with hot chocolate. Serve with a freshly baked chocolate chip cookie on the side.
