Some desserts feel like a hug, and apple pie is one of them. The trouble is that a proper pie means rolling pastry, chilling dough and fussing over a lattice top. This apple pie cake skips all of that. It uses just four everyday ingredients, apples, flour, sugar and butter, and needs no eggs and no mixer. Half of the buttery crumb forms the base, soft cinnamon-scented apples go in the middle, and the rest of the crumb becomes a golden, crumbly top. Here is a simple five-step way to make it at home, even if you have never baked before.
