This apple bread pudding with warm vanilla sauce is the ultimate comfort food from Gramma's kitchen. It is great for using up bread and apples.
For the best texture, use day-old or slightly stale bread as it absorbs the custard more effectively without becoming soggy. Brioche or challah can elevate the richness. Ensure apples are sliced uniformly for even cooking; a mix of sweet and tart varieties like Honeycrisp and Granny Smith can add depth. When making the vanilla sauce, bring it to a gentle boil to fully dissolve the sugars and butter, then remove from heat before stirring in vanilla to preserve its delicate flavor. Do not overbake the pudding; it should be just set in the center with tender apples, preventing a dry result. Serve warm, perhaps with a dollop of crème fraîche or a scoop of vanilla bean ice cream for an extra luxurious touch.
