In a small microwave-safe bowl, melt 3 tablespoons butter until just melted. With a fork, stir in 3 Tbsp. sugar, 2 Tbsp. brown sugar and 1 Tbsp. cinnamon until a smooth spreadable mixture forms, set aside.
In a medium bowl, whisk together the eggs, milk, 2 tsp. Cinnamon and Vanilla, set aside.
After trimming the crusts from each slice of bread, roll one slice out to about ⅛-inch thickness with a rolling pin. Spread each slice with a thin layer of the butter mixture and roll up tightly. Repeat with remaining bread slices and butter mixture.
Place 3 tablespoons butter in a large non-stick pan and let melt over medium heat. Dip one roll at a time in the egg mixture and place in the pan. Allow roll ups to cook for 1-2 minutes per side until golden brown and slightly crisp on the outside.
Serve immediately with maple syrup.
