Description
A decadent mash‑up of fudgy brownies and chewy chocolate chip cookies, baked together in layers to create irresistible ‘brookies’. Makes about a dozen generous bars.
Ingredients
- Cookie dough: ⅓ cup unsalted butter (just melted), ⅓ cup dark brown sugar (packed), 2 Tbsp granulated sugar, 1 large egg yolk, 1 tsp vanilla extract, ¾ cup all‑purpose flour, ¼ tsp baking soda, heaping ¼ tsp salt, ½ cup dark chocolate chips (plus extra for topping)
- Brownie batter: 5 oz bittersweet chocolate (70 %), 6 Tbsp unsalted butter, 2 large eggs, ¾ cup granulated sugar, ½ tsp vanilla extract, ¼ tsp salt, ⅓ cup all‑purpose flour
Instructions
- Preheat oven to 350 °F and line an 8×8‑inch pan with parchment, leaving a bit of overhang for easy removal.
- Make cookie dough: gently melt butter until mostly liquid, then stir in brown and granulated sugar. Mix in egg yolk and vanilla, then fold in flour, baking soda, salt and chocolate chips. Roll into ~18 small balls; chill.
- Make brownie batter: melt chocolate and butter gently until smooth. Whisk eggs, sugar, vanilla and salt until pale and thick, then stir in melted chocolate. Fold in flour until just combined.
- Spoon half the brownie batter into the pan, spreading evenly. Flatten 9 cookie dough balls into discs and arrange in three rows of three atop the batter.
- Spread remaining brownie batter over cookies, then flatten and nestle remaining cookie dough on top.
- Bake 20 min at 350 °F, then reduce heat to 325 °F and bake another 15–20 min, or until a skewer inserted into brownie shows moist crumbs (not wet batter).
- Cool completely before lifting out with parchment and cutting into 12 squares.
Notes
- Use a kitchen scale for best accuracy, as per recipe guidance :contentReference[oaicite:0]{index=0}.
- Chilling the cookie dough helps maintain distinct layers :contentReference[oaicite:1]{index=1}.
- Skewer should come out with a few moist crumbs—not wet—for fudgy brownie texture :contentReference[oaicite:2]{index=2}.
- Store in airtight container at room temperature for up to 4 days; add a slice of bread to keep them soft :contentReference[oaicite:3]{index=3}.
