Heat pancake griddle to 375°F. Lightly grease griddle.
Measure Buttermilk Pancake Mix by lightly spooning into measuring cup and leveling it off. In a medium bowl, combine pancake mix and cold coffee until just combined. Do not over-mix. Let batter sit for 2 minutes.
Pour slightly more than 1/4 cup of batter per pancake onto griddle. Cook for 1-1 1/2 minutes per side, turning only once.
Using an electric mixer with whip attachment, beat mascarpone, sugar and Marsala (if using) until smooth and fluffy. Gently fold whipped cream into mascarpone until well blended.
Layer pancakes with Mascarpone Cream and sprinkle with cocoa powder or chocolate shavings as desired.
