The recipe is simple but has a few royal upgrades.

Without them, this bread and butter pudding is a total crowd-pleaser.

Amaretto-soaked raisins take some prep time.

I infused mine in three ounces of amaretto for an hour but overnight would be ideal.

“Well, it looks like you could make a lot of bread pudding with that bottle!”

Cubed bread is the first layer in a buttered dish, followed by the tender amaretto raisins.

Layer in your butter-dipped bread triangles, and cover everything with custard.

Let it rest for 20 minutes before popping it into a water bath to bake until it’s set.

It’s done when golden brown on top and gently jiggly toward the center.

For me, that was 45 minutes at 350F.

This wonderfully forgiving bread and butter pudding easily crowns anyone queen of dessert.
