Dry the bread - Preheat the oven to the lowest heat setting, for my oven it was 170°F (80°C). Cut leftover milk bread into 1” cubes, spread them on a large baking sheet and toast for 1 hour. Turn off the oven, remove the bread cubes and allow them to cool completely, approximately 30 minutes to 1 hour.
454 grams leftover sourdough pumpkin milk bread
Make pumpkin butter - While the bread is toasting, cook the pumpkin with brown sugar and pumpkin pie spice in a small sauce pan over medium heat, stirring constantly until the mixture thickens, about 5 - 7 minutes. Set aside to cool.
200 grams pumpkin puree, 50 grams brown sugar, 1 teaspoon pumpkin pie spice
Prepare the custard - Beat together eggs, brown sugar, vanilla, salt and cooled pumpkin butter in a large mixing bowl until thoroughly combined. Then stir in the half and half.
5 large eggs, 150 grams brown sugar, Couple pinches of kosher salt, 10 grams pure vanilla extract, All of the pumpkin butter, 480 grams half & half
Soak the bread - Toss cooled dry bread cubes in the custard mixture evenly and let them soak for at least 2 hours and up to overnight in the refrigerator. Turn the mixture once or twice to make sure it’s soaking evenly.
Make the streusel - Whisk together sugar, flour, pumpkin pie spice and salt in a small mixing bowl. Add cold cubed butter pieces to it and press them into the flour mixture with the tips of your fingers until the mixture resembles wet sand. Freeze (or refrigerate) until ready to use.
100 grams granulated sugar, 64 grams all-purpose flour, Couple pinches of kosher salt, 1 teaspoon pumpkin pie spice, 57 grams unsalted butter
Preheat the oven - Set the oven rack in the middle of the oven and preheat to 350°F (180°C).
Bake - Butter a 10” square baking pan generously. Add pumpkin bread pudding mixture to the pan, top with streusel and bake in the preheated oven for 45 - 50 minutes, until the center is only slightly jiggly. Remove from the oven and allow to cool slightly to set.
Make miso caramel - While the bread pudding is baking, make the miso caramel. Heat granulated sugar, corn syrup and water in a heavy bottom stainless steel pan over medium heat without stirring. You can swirl the pan occasionally to ensure all the sugar melts and heats evenly. When the liquid turns amber, take it off the heat. Immediately add the butter to it and stir, the mixture will bubble rapidly, keep whisking until smooth. Then stir in cream and miso paste, the mixture will bubble again, just keep whisking until smooth. Finally, stir in the vanilla last. Transfer to a jar.
150 grams granulated sugar, 40 grams corn syrup, 30 grams water, 57 grams unsalted butter, 60 grams heavy whipping cream, 25 grams white miso paste, ½ teaspoon pure vanilla extract
Serve - Serve your pumpkin bread pudding warm with vanilla ice cream and a generous spoon of miso caramel drizzled on top.
