Preheat your oven to 350°F (175°C).
In a mixing bowl, combine 90g sugar, 110g almond flour, and 100g room temperature butter for the walnut filling.
Add the eggs one at a time and stir well after each addition.
Mix in the vanilla extract, salt, and 75g chopped walnuts. Set the mixture aside.
Peel the pears and cut them into quarters. Place them in acidulated water so they don't brown.
Take the tart shell out of the freezer and spread the walnut filling evenly inside.
Slice the quarter pears into thick slices.
Arrange the sliced pears and whole walnuts on top of the filling.
Bake the tart in the preheated oven until it turns golden brown, usually about 20 minutes.
Once the tart is cooled, glaze the pears with maple syrup and lightly dust the entire tart with powdered sugar.
Serve and enjoy!
