Rustic Chocolate Crostata

Ingredients
For pastry..
2 cups flour
2 tablespoons caster sugar
1 tablespoon icing sugar
5 tablespoons (150g) cold butter, cubed
2-3 tablespoons ice water
For filling...
100g (3.5 oz) milk chocolate
4 tablespoons butter, melted
3 egg yolks
1/2 cup caster sugar
1/2 teaspoon cocoa powder
1/2 teaspoon vanilla
1/4 teaspoon baking powder


To make pastry...
In a food processor pulse, flour, sugar, and butter together until you get the consistency of fine breadcrumbs. Gradually add in the water while the motor is running until the dough comes together. knead into a ball, flatten into a disk, then wrap in plastic wrap and refrigerate for 30 minutes. 
Preheat oven to 350 F(180 C).


To make filling...
Melt butter in the microwave. 
Melt the chocolate in a bowl over a pot of simmering water, gradually stir in the melted butter until you get a smooth consistency. Set aside.
In another bowl whisk egg yolks and sugar together until thick and pale in color. 
Whisk the chocolate mixture into the egg mixture. Then whisk in the cocoa powder, vanilla, and baking powder. 


Cut the dough into four equal pieces. Roll out each piece between two sheets of non stick backing paper or on a floured surface until 2mm thick. Place the four pieces of rolled out dough onto baking trays covered with a silpat or baking paper. Scope a few spoonfuls of the chocolate mixture into the center of the rounds then fold the sides of the dough over the edges to form the crust. It doesn't have to be perfect since this is a "rustic" pie. 
Bake in the oven for about 30 minutes or until crust is golden.
Cool slightly then serve with ice cream.
Makes 4 galettes.
