Banana Bread Pudding

1. Preheat oven to 350°F (175°C).
2. Grease a 9x13 inch baking dish thoroughly with 2 tablespoons of butter.
3. Arrange the 1-inch cubes of brioche bread and sliced bananas evenly in the greased baking dish.
4. For the Custard: In a large bowl, whisk together the large eggs, heavy whipping cream, evaporated milk, sweetened condensed milk, vanilla paste or extract, cinnamon, allspice, brown sugar, and melted unsalted butter until well combined.
5. Carefully pour the custard mixture over the bread and bananas in the 9x13 inch pan.
6. Gently press down on the bread with a spatula or spoon to ensure all the bread cubes are submerged and soak up the custard.
7. Bake at 350°F (175°C) for 45-50 minutes, or until the pudding is set and golden brown on top.
8. Let the banana bread pudding cool slightly before serving.
9. Serve warm, optionally topped with a dusting of powdered sugar, a drizzle of caramel or whiskey caramel sauce, and a scoop of vanilla ice cream.
