For best results, use room-temperature dairy to prevent lumps and mix on low speed to limit air, which can cause cracks; if you want a sturdier crust, add 1 tablespoon sugar to the crumbs and bake 3 extra minutes, and for a silkier filling, warm the heavy cream slightly before adding; avoid overbaking by looking for a 2-inch jiggly center, cool slowly to prevent dramatic temperature changes, and if a crack appears, cover with whipped cream or a thin sugar cookie crumble; the cheesecake keeps well refrigerated for up to 5 days or frozen (without toppings) for up to 2 months, and you can swap sprinkles for crushed holiday sugar cookies for extra crunch.
