Preheat the oven to 350 degrees F. Grease a 9 by 13-inch baking dish with cooking spray or butter.
In a large mixing bowl, whisk together the heavy cream, whole milk, brown sugar, cinnamon, salt, vanilla and egg yolks and set aside.
Add the cubed apples, pecans and cubed bread to the prepared baking dish and toss to combine. Pour the custard over the bread and apple pieces. Carefully toss to coat, making sure that the cubed bread is submerged in the custard, and let stand to allow the bread to soak up the custard, 10 to 15 minutes.
Bake until the center has set, about 45 minutes. Let cool for 5 minutes. Drizzle Caramel Dessert Sauce over the bread pudding. Serve with extra sauce and vanilla ice cream.
In a heavy-bottomed saucepan, combine the sugar, butter, buttermilk and corn syrup. Bring to a boil over medium-high heat and cook for 1 minute. Remove from the heat and slowly add the baking soda (it will foam up), followed by the vanilla and cinnamon. The sauce will thicken as it cools. Serve warm.
