Preheat oven to 350°. Grease the bottom only of a small (4 cups or so)
casserole dish. Peel and core the apples, slice and place in a bowl. Top with
sugar, CINNAMON and VANILLA, toss to coat. Set aside while preparing topping.
Make the streusel by cutting the cold butter into a bowl, adding flour, sugar
and CINNAMON, and rubbing it through your fingers until the streusel is a
coarse, sandy/pebbly texture. Put the seasoned apples into the pan, top
generously with the streusel, and bake at 350° about 30 minutes, until
the streusel is golden brown and the apple is starting to bubble up through
