01 - Preheat oven to 350°F. Grease a standard 12-cup muffin tin thoroughly or line with paper liners.
02 - In a large mixing bowl, whisk together eggs, milk, heavy cream, granulated sugar, vanilla extract, ground cinnamon, and salt until completely smooth and well combined.
03 - Add bread cubes to the custard mixture. Gently fold until every piece is evenly coated. Allow to soak for 5 minutes so the bread absorbs the liquid.
04 - Divide the soaked bread mixture evenly among the 12 muffin cups, pressing lightly to compact each portion.
05 - Bake for 22 to 25 minutes until tops are golden brown and muffins are set throughout.
06 - While muffins bake, combine granulated sugar and ground cinnamon in a small bowl for the coating mixture.
07 - Let muffins cool in the pan for 5 minutes, then carefully remove from the tin.
08 - Brush each warm muffin with melted butter and roll in the cinnamon sugar mixture until thoroughly coated.
09 - Serve warm, optionally accompanied by maple syrup or fresh berries.
