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

Carefully slice the Hawaiian rolls in half horizontally, keeping the tops connected for easier dipping.

Preheat a skillet or griddle over medium heat and add the butter, letting it melt evenly.

Dip each roll half into the egg mixture for a few seconds on each side.

Cook the dipped rolls cut-side down in the skillet for 2-3 minutes until golden brown, then flip and cook the other side.

Arrange the cooked rolls on a platter, dust with powdered sugar, drizzle with maple syrup, and serve warm.
