Preheat oven to 350°.
Spray a 9×13 baking dish with cooking spray.
In a large bowl, whisk together the yogurt, milk, eggs, 1 tsp cinnamon, nutmeg, and ½ cup sugar.
Stir in the apples, raisins, then gently fold in the bread cubes. Pour into the prepared pan.
In a small bowl, stir together 2 Tbsp sugar and 1 tsp cinnamon.
Sprinkle on top the bread pudding. Bake 30-40 minutes until puffed and golden brown.
While the bread pudding is baking, make the caramel sauce.
In a heavy saucepan over medium-low heat, stir together the butter, heavy cream, and brown sugar; bring to a boil.
Reduce heat to low, simmer until the sauce thickens, for about 5 minutes. Pour over bread pudding to serve. Top with vanilla ice cream.
