Apple & Rum Custard Cake

Layered like a proper European fruit kuchen, this cake stacks tart apples and rum-soaked raisins over a buttery shortcrust, then pours a soft vanilla custard over the top that bakes up just set.

Start the raisins early. A half-hour soak in rum plumps them and leaves you with infused liquid that goes straight into the custard, so nothing boozy is wasted.

The smart move here is the layer of buttered breadcrumbs spread over the crust. They soak up the apple juices and keep the bottom from turning soggy, a trick German bakers have leaned on for generations.

Pre-bake the crust and apples briefly before the custard goes in, then bake low until the center is set with the faintest jiggle. Patience is key: leave the springform on until the cake is fully cool so the custard firms without slumping.

Chef Tips

• Choose firm, tart apples like Granny Smith. They hold their shape and balance the sweet custard instead of collapsing into mush.
• Tossing the apples in lemon juice keeps them bright and stops browning while you build the layers.
• Don’t rush the cooling. Cut too soon and the custard runs; fully chilled, it slices clean.
• Press the dough an inch up the sides to build a wall that holds the custard in.

Variations

• Swap golden raisins or dried cherries for the dark raisins, or soak them in brandy instead of rum.
• Add a pinch of cinnamon or nutmeg to the apple toss for a warmer, spiced profile.
