01 - Preheat oven to 350°F. Grease a standard 12-cup muffin tin with butter or nonstick spray.
02 - Divide cubed bread evenly among muffin cups, filling each approximately three-quarters full.
03 - In a large mixing bowl, whisk eggs, whole milk, heavy cream, sugar, vanilla extract, cinnamon, and salt until smooth.
04 - Pour custard mixture evenly over bread cubes in the muffin tin, gently pressing bread to help absorb liquid.
05 - Allow muffin tin to rest for 10 minutes so bread fully absorbs custard.
06 - Top each muffin cup with fresh berries if desired.
07 - Bake for 25 minutes or until tops are golden brown and centers are set.
08 - Let cups cool for 5 minutes. Carefully remove French toast cups from the pan.
09 - Serve warm, dusted with powdered sugar and drizzled with maple syrup.
