Tante Nancy's Apple Crumb Cake

This old-fashioned crumb cake works on a clever principle: the same flour-sugar-margarine mixture forms both the press-in crust and the streusel topping. One bowl, one mixture, two textures.

The trick is in the apples. Cooking sliced tart apples briefly with a little sugar and water before baking softens them just enough so they release their juice now instead of soaking the crust later. Drain them well or you’ll end up with a soggy bottom.

The egg yolk in the dough deserves a mention too. It binds the streusel without adding extra liquid, giving the crumb a shortbready snap rather than a cakey crumb. Press the bottom firmly into the springform so it holds against the apple layer, then scatter the reserved cup of dough loosely on top so it bakes into rough, golden clumps.

Kitchen Tips

• Use firm tart apples like Granny Smith, Braeburn, or Northern Spy. Soft baking apples turn to mush during the pre-cook.
• A pastry blender or two forks gives a coarser crumb than a food processor. You want pebbly, not sandy.
• Let the cake cool at least 20 minutes before releasing the springform. The juice needs time to thicken.
• Dot the top with the extra margarine before baking, it crisps the crumb and adds shine.

Variations

• Add ½ teaspoon of cinnamon and a pinch of nutmeg to the apples for a warmer spiced version.
• Swap half the apples for fresh or frozen blueberries for an apple-berry hybrid.
• Stir chopped walnuts or pecans into the topping crumb for extra crunch.
