• Preheat oven to 350 °F

Make the dough

• Combine 6 ¾ oz hazelnuts and 1/2 cup of the flour in a food processor. Pulse until there are no chunks and the nuts are finely ground. Add 8 oz granulated sugar, ½ teaspoon baking powder, ¼ teaspoon salt and 1 teaspoon cinnamon and pulse to combine. Add 8 oz unsalted butter, and pulse until the pieces of butter are no larger than a pea. Add the rest of the flour and pulse until the mixture looks like wet sand. Add 3 egg yolks and 1 teaspoon vanilla and process until the mixture begins to form a ball.
• Dump the dough onto a floured surface and knead until the ingredients are completely combined. Divide the dough into 2 unequal portions (⅔ & ⅓). Wrap each piece of dough and refrigerate for several hours until firm.

Assemble the tart

• Roll the larger portion of dough to fit a 12" tart pan with a removable bottom. Piece together any bits that crack off as you transfer the dough to the pan. Alternately, skip rolling and use a small spatula or your hands to push the dough evenly into the pan.
• Spoon the cranberry filling into the lined tart shell. Roll the remaining portion of dough to a 12" round. Cut the round into 1" strips. Use a small offset spatula to lift the strips onto the cranberry filling. Arrange the strips in a lattice pattern and press in place to stick to the edges of the pan. Use a small knife to trim the edge of the tart flush with the pan. Bake until the dough is golden brown and set in the center, about 40-45 minutes. Cool completely before removing the pan rim. Sprinkle with powdered sugar before serving
