1Heat griddle or skillet over medium-high heat (375°F). Brush with vegetable oil.
2In medium bowl, beat pancake ingredients with whisk. Use tablespoon or small ice cream scoop to pour batter on hot griddle to form mini pancake rounds. Cook until bubbles break on surface. Turn and cook until golden brown. Transfer pancakes to cooling rack.
3In small bowl, beat mascarpone cheese, orange peel and powdered sugar with electric mixer on medium speed until well beaten. Decrease to low speed, and gently beat in champagne until smooth. In another small bowl, beat cream on high speed until stiff peaks form. Using spatula, gently fold whipped cream into mascarpone mixture.
4To make a pancake stack, place 1 mini pancake on plate or serving platter. Spread orange marmalade over pancake. Repeat with pancake and marmalade 2 more times. Top with champagne cream, and garnish with orange peel.
