Cut the bread into medium-sized cubes and place them in a large bowl. I like using day-old bread because it absorbs the custard beautifully without falling apart. If your bread feels too fresh, lightly toast it for a few minutes.
Add the raisins to the bread mixture so they soften while baking. Drizzle melted butter over the cubes for extra richness and flavor. Toss everything gently to coat evenly.
In another bowl, whisk together the eggs, sugar, milk, heavy cream, vanilla, cinnamon, nutmeg, salt, and Irish whiskey. Whisk until the mixture becomes smooth and creamy. The warm spices make the kitchen smell amazing already.
Pour the custard slowly over the bread cubes. Press the bread gently into the liquid so every piece absorbs the mixture evenly. Let it sit for about 15 minutes before baking.
Grease your baking dish lightly with butter or cooking spray. Transfer the soaked bread mixture into the dish and spread it evenly. Make sure the raisins are distributed throughout the pudding.
The top should look moist but not overly wet. If you want extra texture, sprinkle a little cinnamon sugar over the top before baking.
Preheat the oven to 350°F (175°C). Place the baking dish in the oven and bake for about 40–45 minutes. The top should turn golden brown while the center stays soft and custardy.
You’ll know it’s done when a knife inserted in the center comes out mostly clean. Let the pudding cool slightly before serving so it sets properly.
While the pudding bakes, melt butter in a saucepan over medium heat. Stir in brown sugar and heavy cream until smooth and bubbling. The sauce should look glossy and rich.
Remove the pan from heat and slowly stir in the Irish whiskey and vanilla extract. Be careful because the whiskey aroma becomes strong at first but mellows beautifully.
Slice the warm bread pudding into squares and drizzle generously with whiskey sauce. I love serving it while still warm because the sauce melts right into the pudding.
For extra indulgence, top it with whipped cream or vanilla ice cream. The contrast between warm pudding and cold ice cream tastes incredible.
