Combine flour, sugar, salt, and baking powder in a food processor. Pulse for 10 seconds. Add vanilla extract and continue to pulse. Begin adding cold butter, 1 tablespoon at time. Once all butter is added, begin adding ice cold water, 1 tablespoon at a time. Pulse until dough becomes a ball.

Add flour onto a work surface and roll out dough into a large circle. Add dough to a pie pan and gently press against the pie pan, cutting off any additional scraps that do not fit into the dish. Add to the freezer.

Preheat oven to 350 degrees.

Combine all of the ingredients for the filling in a mixing bowl and whisk until thoroughly combined.

Remove pie pan from freezer and pour filling into the dish. Bake for 1 hour to 1 hour and ten minutes.

Freeze for 3 hours or chill in the refrigerator overnight.

If you'd like to make meringue to add to the pie, whip up 4 egg whites and gradually add sugar until stiff peaks form!

Eat up!
