In a 12-inch oven safe pan (I use cast iron, if you use something else I recommend greasing the pan), layer cubed bread evenly. Place cherries on top of the bread cubes.
In a medium bowl, whisk eggs, bourbon, maple, cherry juice, zest, bitters, and sugar.
Next, whisk in the cream and milk.
Pour the egg mixture evenly over the bread. Cover and chill for 2 hours before baking.
Pre-heat oven to 350°F. Uncover the bread pudding and bake for 50 minutes. Just before the pudding is done cooking, mix together the caramel and maple syrup. Remove bread pudding from the oven and allow it to rest for about 5 minutes. It will be very puffy when it comes out of oven and will sink as it cools.
Plate and top with a little maple caramel sauce and a little powdered sugar.
