Hot Fudge Pudding Cake 1

This is one of those old-fashioned desserts that feels like a magic trick. You pour a chocolate cake batter into a pan, sprinkle a cocoa-sugar mixture on top, then dump hot water over the whole thing without stirring. It looks like a disaster going into the oven, but 35 minutes later, the batter has risen into a tender chocolate cake on top, and the cocoa-sugar-water has transformed into a thick, dark fudge sauce pooled underneath.

The science is straightforward: the denser batter rises through the lighter sugar-water as it bakes, and the hot water dissolves the cocoa and sugars into a rich sauce that stays beneath the cake layer. Brown sugar in the topping gives the fudge sauce a deeper, more caramel-like flavor than white sugar alone would.

Scoop it out with a big spoon, making sure to dig down to the sauce at the bottom. Top with whipped cream.

Kitchen Tips

• Do not stir after adding the hot water. This is the hardest instruction to follow, but stirring mixes the layers and ruins the separation.
• The center will look slightly underset when done. That’s correct. It firms up during the 15-minute rest.
• Use truly hot (near-boiling) water. Lukewarm water won’t dissolve the cocoa mixture properly and the sauce will be grainy.
• Serve warm, not cold. The fudge sauce thickens and loses its gooey quality as it cools.

Variations

• Add a teaspoon of instant espresso powder to the cocoa-sugar topping for a mocha fudge sauce.
• Fold chopped walnuts or pecans into the batter for crunch against the gooey sauce.
• Serve with vanilla ice cream instead of whipped topping for a hot-cold contrast.
