Pre-heat oven to 425 degrees.
In a blender, combine eggs, milk, sugar, vanilla, flour, cinnamon, and salt until well blended and frothy.
Stir mini chocolate chips into egg mixture.
Lightly brush 12-cavity muffin tin with melted butter.
Pour the batter into the muffin tin, filling cavities about ½ way with batter. Transfer tin to oven. Bake until pancakes are puffed and golden, about 11 or 12 minutes. Pancakes will begin to deflate when removed from oven.
Remove pancakes from muffin tin and lightly dust with confectioners' sugar.
Top with Cinnamon Whipped Cream and additional mini chocolate chips, if desired.
