5 tablespoons unsalted
8 cups day-old white bread, such as French or Italian, cut into 1-inch cubes (toast if fresh)
2 cups heavy cream
2 cups milk
4 large eggs
1 cup light brown sugar
1/2 cup granulated sugar
2 teaspoons vanilla extract
1 1/2 teaspoons ground cinnamon
Pinch freshly grated nutmeg
5 tablespoons banana liqueur
2 cups mashed ripe bananas, about 4 small
3/4 cup chopped walnuts, toasted
Buttery Rum Sauce, recipe follows
Whipped Cream, for garnish
Fresh mint sprigs, for garnish
Preheat the oven to 350 degrees F.
Lightly grease a 9 by 13-inch baking dish with 1 tablespoon of the butter and set aside.
Place the cubed bread in a large mixing bowl. In a small saucepan, melt 4 tablespoons of the butter over medium heat and pour the butter over the bread cubes. Using a rubber spatula, toss to evenly distribute the butter.
Combine the cream, milk, eggs, brown sugar, granulated sugar, vanilla, cinnamon, nutmeg, salt, and banana liqueur in a medium mixing bowl, whisking to combine. Pour the cream mixture over the bread cubes and stir to combine. Let sit for 30 for 45 minutes, or until the bread is soft and has absorbed most of the liquid.
Stir in the mashed bananas and walnuts. Pour the mixture into prepared dish and bake, uncovered, for 45 to 50 minutes, until the top is golden brown and crispy and the pudding is firm in the center. Prepare the Buttery Rum Sauce while the pudding is baking.
Remove the pudding from the oven and cool on a wire rack for 15 minutes before serving. Serve warm with Buttery Rum Sauce and whipped cream, if desired.
