02 - 1/4 cup powdered sugar
03 - 1/4 teaspoon salt
04 - 1/2 cup cold unsalted butter, cubed
05 - 1 large egg yolk
06 - 1 to 2 tablespoons cold water

07 - 7 oz dark chocolate (70% cocoa), chopped
08 - 1/2 cup unsalted butter, cubed
09 - 3/4 cup granulated sugar
10 - 1/4 cup brown sugar
11 - 2 large eggs

# Directions:
01 - Preheat oven to 350°F. Grease a 9-inch tart pan with removable bottom.
02 - Whisk together flour, powdered sugar, and salt. Incorporate cold butter by rubbing with fingertips or pastry cutter until coarse crumbs form. Add egg yolk and 1 tablespoon cold water, mixing until dough just holds. Add extra water if necessary. Form dough into disk, wrap, and chill for 15 minutes.
03 - Roll dough on lightly floured surface and press into prepared tart pan. Trim excess and prick base with fork. Line with parchment and fill with pie weights or dried beans. Bake 15 minutes, remove weights and parchment, then bake another 5 minutes until lightly golden. Cool slightly.
04 - Melt chocolate and butter over simmering water or in 20-second microwave bursts, stirring until smooth. Cool slightly.
05 - Whisk in granulated sugar, brown sugar, eggs, vanilla extract, and salt until combined. Gently fold in flour until just incorporated, avoiding overmixing.
06 - Pour brownie batter into cooled tart shell and smooth the surface.
07 - Bake for 18 to 20 minutes until edges are set but center remains slightly soft. Avoid overbaking; center will firm upon cooling.
08 - Cool completely on wire rack. Dust with cocoa powder or powdered sugar and add fresh berries or whipped cream as desired before serving.
