# How-To:
01 - Preheat oven to 350°F. Grease a 9-inch tart pan with a removable bottom.
02 - Whisk flour, powdered sugar, and salt in a bowl. Rub in cold butter until mixture resembles coarse crumbs. Add egg yolk and 1 tablespoon cold water, mixing until dough forms; add more water if needed. Shape into disk, wrap, and chill for 15 minutes.
03 - Roll dough on 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 paper, then bake another 5 minutes until lightly golden. Let cool slightly.
04 - Gently melt dark chocolate and butter together in heatproof bowl over simmering water or in 20-second microwave bursts, stirring until smooth. Cool slightly.
05 - Whisk in granulated sugar, brown sugar, eggs, vanilla, and salt into melted chocolate mixture until incorporated. Fold in flour until just combined, avoiding overmixing.
06 - Pour brownie batter into cooled tart shell and smooth top. Bake 18 to 20 minutes until edges are set but center remains slightly soft; avoid overbaking.
07 - Allow tart to cool completely on wire rack. Dust with cocoa powder or powdered sugar and garnish with fresh berries or whipped cream before serving.
