Gather your dough ingredients so that you have everything close at hand on the counter or table.
Prepare the Dough
In a food processor, add all-purpose flour, granulated sugar, and baking powder. Mix to combine. Drop slices of cold butter into the work bowl, pulsing just until crumbs form.
Add eggs and sour cream and pulse again just until mixed. Try not to overmix. Place dough in a bowl and cover with plastic wrap. Refrigerate for 2-3 hours.
Make the Apple Filling
Once the dough has chilled for the recommended time, preheat oven to 350F degrees. Coat the bottom and sides of a 9-inch springform pan with baking spray.
Peel, core, and thinly slice the Granny Smith apples. Place in a microwave-safe bowl and heat for 3 minutes to help soften the apples during the baking process.
Remove apples from microwave, and mix in the lemon juice, brown sugar, all-purpose flour, and ground cinnamon. Mix together until combined.
Assemble the Dessert
Roll half of the dough onto a lightly floured surface, big enough to fit the springform pan. Carefully, place in the bottom of the prepared pan. - Alternately, you may press half of the chilled dough into the prepared springform pan to cover the bottom of the pan.
Spoon the apple filling on top of the dough.
Then either 1) roll the remaining dough into a circle big enough to cover the top of the pan, or 2) crumble the dough over the apples, lightly pressing it down with your fingers.
Bake in preheated oven for 45-50 minutes until the top crust is lightly browned and the dough is cooked in the center.
Allow to cool before removing the sides of the springform pan. If you're daring, you may try to transfer the dessert to a cake plate.
Generously dust the top with powdered sugar to cover. Serve with whipped topping or ice-cream.
This recipe will serve 8-10 people.
