Instructions
Par-Bake Tart Shell
Preheat oven to 350° (note: Tart shell should be cold before baking)
Using a dinner fork, poke holes in dough in the bottom of the pan. Sprinkle a dusting of flour on dough (this helps prevent foil from sticking to the raw dough).
Place a sheet of aluminum foil on top of dough. The foil should reach to the bottom of pan and over the sides.
Place pie weights (or dried beans or rice) on top of the foil. The weights should cover the bottom of the pan and halfway up the sides.
Bake for 15 minutes at 350°. Remove from oven, lift foil and weights out of the pan, return to oven and bake another 10 minutes. Set aside to cool.
The tart shell should only be partially baked and starting to turn golden. It will be fully baked after the tart is assembled and baked.
Make the Walnut Frangipane
Preheat oven to 350℉
Place brown sugar and softened butter in the bowl of a stand mixer fitted with the paddle attachment (note: a hand mixer may also be used).
Begin mixing brown sugar and butter together on medium speed. Continue to mix until the mixture is lightened and creamy (approximately 3 - 4 minutes). Scrape bottom and side of the bowl as needed.
Add ground walnuts and granulated sugar and mix on low speed until combined.
Begin adding the room temperature eggs one at a time, mixing on low speed until combined. Scrape bottom and sides of bowl between each addition.
Remove bowl from the mixer and fold in the flour, cinnamon and baking powder.
Assemble the Tart
Wash apples to remove any dirt or wax. It is not necessary to peel the apples.
Using an offset spatula, spread the frangipane evenly in the bottom of the tart shell (tart shell should be completely cooled).
Slice apples thinly (approximately ⅛" thick).
Insert apples in the frangipane already spread in the tart shell. Place down so the apple peel is facing upwards. Work in a circle starting at the outer edge of the tart shell and work inwards.
Bake / Serve Tart
Place tart pan on a cookie sheet and bake for 30 - 35 minutes in preheated oven (350℉). The frangipane will have risen and be set when the tart is done.
Cool for approximately two hours. Remove tart by pressing upwards on removeable pan bottom.
