Start the oven preheating to 200℃ / 400℉.
Generously butter a large deep pie dish, or 8"x8" / 20cmx20cm baking dish. This recipe could easily be doubled to fill a 9"x13" / 23cmx33cm pan, though you may also need to increase the baking time a little. Peel, core, and slice the apples.
In a mixing bowl, place your dry dough ingredients and stir well to combine. Work the butter chunks through to make a crumbly mixture.I started out trying to cut the butter in with a fork, but soon got my hands in there. Lay the apples into the buttered dish, and sprinkle the cinnamon over top.
Add the crumb topping.
Bake for around 20-30 minutes, or until browned on top and bubbling up around the edges. The smell will be amazing toward the end.Mine went for 25 minutes in this pan and oven, and possibly could have gone a few minutes longer for more browning. Using all white sugar here, though, it won't get as dark. Let rest for 15 minutes, then serve warm with some vanilla ice cream or the classic here: vaniljsås, or vanilla custard.
