# How-To Steps:
01 - Preheat oven to 350°F. Grease a 9-inch tart pan with removable bottom.
02 - In a bowl, whisk together flour, powdered sugar, and salt. Add cold butter and rub in with fingertips or pastry cutter until mixture resembles coarse crumbs. Mix in egg yolk and 1 tablespoon cold water until dough just forms, adding an extra tablespoon if needed. Form disk, wrap, and chill 15 minutes.
03 - Roll dough on lightly floured surface and press into tart pan. Trim excess, prick base with fork. Line with parchment and fill with pie weights or dried beans. Bake 15 minutes, remove weights and parchment, then bake an additional 5 minutes until lightly golden. Cool slightly.
04 - Melt dark chocolate and butter in heatproof bowl over simmering water or microwave in 20-second intervals, stirring until smooth. Allow to cool slightly.
05 - Whisk granulated sugar, brown sugar, eggs, vanilla, and salt into melted chocolate mixture. Fold in flour gently until just combined; avoid overmixing.
06 - Pour brownie batter into cooled tart shell and smooth top evenly.
07 - Bake for 18 to 20 minutes until edges are set but center remains slightly soft. Avoid overbaking; tart will firm as it cools.
08 - Cool completely on wire rack. Dust with cocoa powder or powdered sugar and garnish with fresh berries or whipped cream if desired before serving.
