In a large mixing bowl, whisk together eggs, milk, heavy cream, vanilla extract, cinnamon, and sugar until smooth and pale yellow.

Slice Hawaiian rolls in half horizontally to create pockets.

Preheat a non-stick skillet over medium heat and melt butter; dip each roll half into egg mixture, coating both sides.

Place dipped rolls onto the skillet and cook for 2-3 minutes on each side until golden brown.

Arrange French toast on a platter, dust with powdered sugar, and drizzle with maple syrup before serving.
