Preheat your oven to 350°F and butter a 9x13-inch baking dish generously. Spread bread cubes evenly across the bottom, then scatter diced apples and pecans throughout. This setup ensures every bite contains fruit and nuts distributed evenly.

In a medium bowl, whisk together eggs, milk, heavy cream, brown sugar, vanilla extract, cinnamon, nutmeg, and salt until fully combined. The mixture should be smooth with no visible egg streaks. Pour this custard mixture slowly over bread cubes, letting it soak through completely before proceeding.

Gently press down on bread with the back of a spoon to ensure cubes absorb custard thoroughly. Let the dish sit for 5-10 minutes so flavors meld together while this cozy sweet brunch recipe becomes properly saturated.

Dot the top with small butter pieces and drizzle maple syrup evenly across the surface for sweetness and richness. Sprinkle baking powder over everything and gently toss the top layer to distribute it. Bake at 350°F for 35-40 minutes until the top is golden brown and a knife inserted in center comes out clean.

Remove from oven and let cool for 5 minutes before serving warm for maximum enjoyment and safety.
