Apple-Pie Cake

You can make this delicious, dramatic dessert with just six common ingredients. It's actually a cross between a pie and a fruit crisp: The brown-sugar crumb mixture serves as the crust as well as the topping. Dust the top of the cake with confectioners' sugar. Put some sugar in a standard sieve, hold it above the cake, and tap the edge lightly as you move the sieve over the surface of the cake.
