# Instructions:
01 -
Preheat oven to 350°F (175°C). Line an 8x8-inch square metal baking pan with parchment paper, leaving a 2-inch overhang on each side. Secure the edges with binder clips.
02 -
Melt butter gently until just melted but still creamy. Combine melted butter with dark brown sugar and granulated sugar in a large bowl. Mix in egg yolk and vanilla extract. Add flour, baking soda, and salt; fold to combine. Fold in dark chocolate chips.
03 -
Roll cookie dough into approximately 18 small balls. Place on a lined plate or tray, cover, and refrigerate while preparing the brownie batter.
04 -
Melt bittersweet chocolate and butter together over very low heat, stirring constantly until smooth. In a large bowl, whisk eggs, granulated sugar, vanilla extract, and salt until pale and thick. Beat in the warm chocolate mixture. Sprinkle flour over the mixture and fold until evenly combined.
05 -
Spread half of the brownie batter evenly in the prepared pan. Flatten half of the chilled cookie dough balls into discs and arrange over the batter in a 3x3 grid. Spread remaining brownie batter over the cookie dough and top with the remaining flattened discs.
06 -
Bake at 350°F (175°C) for 20 minutes. Reduce temperature to 325°F (163°C) and continue baking for 15 to 20 minutes or until a skewer inserted comes out with moist crumbs attached.
07 -
For a 9x9-inch pan, place half of the cookie dough balls directly on the bottom, spread brownie batter over them, and top with remaining dough balls. Bake at 350°F (175°C) for approximately 30 minutes.
# Notes:
01 -
Melt butter gently to retain a creamy texture which enhances dough consistency.
02 -
Chilling cookie dough balls prevents spreading and maintains chewy texture in the baked layers.
