1Preheat the oven to 375°F (190°C). Generously butter a 6-cup muffin tin.
2Melt the butter in a skillet over medium heat. Add the diced apples and brown sugar; cook 4–5 minutes, stirring, until softened and lightly caramelized. Set aside.
3In a large bowl, whisk the eggs, milk, vanilla, cinnamon, salt, and granulated sugar until smooth.
4Add the bread cubes to the custard and toss to coat. Let soak for 2 minutes.
5Fill each muffin cup halfway with soaked bread, spoon some caramelized apples into each cup, then top with the remaining bread. Drizzle any leftover custard over the tops.
6Bake 18–20 minutes, until puffed and golden on top.
7Cool 5 minutes in the tin, then run a knife around the edges and lift the cups out. Serve warm with maple syrup and whipped cream.
