Pie Dough

• Combine two thirds of flour with sugar and salt in the bowl of a food processor and pulse twice to incorporate. Spread butter chunks evenly over surface. Pulse until there is no dry flour and dough just begins to collect in clumps. Using a rubber spatula, spread the dough evenly around the bowl of the food processor. Sprinkle with remaining flour and pulse until dough is just barely broken up. Transfer the dough to a large bowl.

• Sprinkle with ice water, then, using a rubber spatula, fold and press the dough until it comes together into a ball. Divide the ball in half. Form each half into a small disk. Wrap tightly in plastic and refrigerate for at least 2 hours before rolling and baking.

Crumble Topping

• Combine all topping ingredients using a fork until completely mixed and crumbly. This step is really easy.

Filling

• Peel, core, and slice the apples into thin slices. Toss apple slices with sugar, lemon juice, cinnamon, and flour.
• Layer the apple slices in pie shell and top apple slices with topping until they're all covered.
• Bake at 2020 for 15 minutes, reduce heat to 175 degrees and bake an additional 45-55 minutes. (Poke the center of the pie to make sure the apples are soft all of the way through).
• Enjoy warm or at room temperature, with a scoop of vanilla ice-cream on top. Do not skip this step!
