Slice the apples about 1/4 inch thick so they soften at the same rate. Keep the butter cold so the topping bakes into crisp clusters instead of a flat, dense layer. Firm apples such as Granny Smith, Honeycrisp, or Braeburn hold their shape best. If the topping browns before the apples are tender, tent the ramekins loosely with foil for the last 10 minutes. Cover and refrigerate leftovers for up to 3 days, and reheat in a 325°F oven for 10–12 minutes to bring back some of the crunch. The ramekins can be assembled earlier in the day and refrigerated unbaked; add a few extra minutes to the bake time. Calories per serving: ~395 kcal (estimated)
