Pithiviers

1 . Stage

Preheat the oven to 400 degrees F (200 degrees C). Line a baking sheet with parchment paper.

2 . Stage

Combine butter and sugar in a bowl and beat with an electric mixer until well combined. Add almond flour, 2 egg yolks, and rum; mix until frangipane is smooth.

3 . Stage

Roll out puff pastry sheets and cut into 2 equal circles. Place the first circle on the baking sheet and pierce several times with a fork. Spread frangipane on the circle, leaving a 1/2 inch border.

4 . Stage

Brush uncovered puff pastry edge with a little water and lay the second puff pastry circle on top. Seal the edges by pressing together.

5 . Stage

Using a sharp knife, cut a decorative pattern around the rim. Trace decorative lines onto the surface without cutting all the way through. Beat remaining egg yolk with a fork; brush over the top.

6 . Stage

Bake in the preheated oven for 10 minutes. Reduce oven temperature to 350 degrees F (175 degrees C) and bake until pastry is puffed up and lightly browned, about 20 minutes more.

Remove from the oven and dust with confectioners' sugar.

8 . Stage

Set an oven rack about 6 inches from the heat source and preheat the oven's broiler.

Place pithiviers under the broiler and broil until a golden, shiny crust forms, 1 to 2 minutes. Watch carefully to make sure it doesn't burn.
