# How to Make It:
01 - Preheat the oven to 350°F and grease a 9-inch tart pan with removable bottom.
02 - Combine flour, powdered sugar, and salt. Rub in cold butter until mixture resembles coarse crumbs. Add egg yolk and 1 tablespoon cold water, mixing until dough forms; add an extra tablespoon of water if necessary. Shape into a disk, wrap, and refrigerate for 15 minutes.
03 - On a lightly floured surface, roll out dough and press into tart pan. Trim excess and prick base with fork. Line with parchment paper and fill with pie weights or dried beans. Bake for 15 minutes, remove weights and paper, then bake 5 minutes more until light golden. Allow to cool slightly.
04 - Melt dark chocolate and butter together over simmering water or in short microwave bursts, stirring until smooth. Let cool slightly.
05 - Whisk in granulated sugar, brown sugar, eggs, vanilla extract, and salt until combined. Gently fold in flour without overmixing.
06 - Pour brownie batter into cooled tart shell, smoothing the top. Bake for 18 to 20 minutes until edges are set but center remains slightly soft. Avoid overbaking.
07 - Allow the tart to cool completely on a wire rack. Dust with cocoa powder or powdered sugar and garnish with fresh berries or whipped cream as desired before serving.
