The sweet-and-spicy cinnamon crumb topping is unquestionably the best part of any coffee cake. So naturally, we made it the star of this dessert. Here, the big, buttery crumbs sit atop an elegant crescent roll twist, which is more striking to serve (and simple to bake) than a traditional coffee cake. For the filling, you'll want to opt for granny smith or pink lady apples, which maintain some texture when cooked and don't get mushy. It's okay if your twist doesn't look perfectan apple piece or two may poke through the doughbecause you can cover up any imperfections with your oversized crumbs.
