# Step-by-Step:
01 - Preheat oven to 350°F. Grease a 9-inch tart pan with removable bottom.
02 - Whisk flour, powdered sugar, and salt. Incorporate cold butter with fingertips or pastry cutter until coarse crumbs form. Add egg yolk and 1 tablespoon cold water; mix to form dough, adding more water if necessary. Shape into disk, wrap, and chill for 15 minutes.
03 - Roll dough on floured surface. Press into tart pan and trim excess. Prick base with fork, line with parchment, and fill with pie weights. Bake 15 minutes. Remove weights and paper, bake 5 minutes more until lightly golden. Cool slightly.
04 - Melt chocolate and butter over simmering water or in microwave until smooth; cool slightly.
05 - Whisk in granulated sugar, brown sugar, eggs, vanilla, and salt until combined. Fold in flour gently; avoid overmixing.
06 - Pour batter into tart shell and smooth surface. Bake 18 to 20 minutes until edges set and center is slightly soft. Do not overbake; firmness will increase when cooling.
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.
