Ingredients

  • Brownie layer: ½ cup unsalted butter, melted; ⅓ cup granulated sugar; ⅓ cup brown sugar; 2 large eggs; 1 tsp vanilla extract; ½ cup all‑purpose flour; ¼ cup unsweetened cocoa powder; ¼ tsp salt; ½ cup semi‑sweet chocolate chips (optional)
  • Cookie layer: ½ cup unsalted butter, softened; ½ cup brown sugar; ¼ cup granulated sugar; 1 large egg; 1 tsp vanilla extract; 1 cup all‑purpose flour; ½ tsp baking soda; ¼ tsp salt; ½ cup chocolate chips

Instructions

  1. Preheat oven to 350°F (175°C). Line an 8×8‑ or 9×9‑inch pan with parchment.
  2. In a bowl, whisk melted butter, granulated sugar, brown sugar, eggs, and vanilla until smooth.
  3. Stir in cocoa powder, flour, and salt until just combined. Fold in chocolate chips if using. Spread brownie batter in prepared pan.
  4. In another bowl, cream softened butter with brown and granulated sugar. Mix in egg and vanilla.
  5. Stir in flour, baking soda, and salt until combined. Fold in chocolate chips.
  6. Drop spoonfuls of the cookie dough over the brownie layer, gently spreading so some brownie peaks through.
  7. Bake for 30–35 minutes, until the cookie top is golden and a toothpick comes out with moist crumbs but not raw batter.
  8. Let cool completely in the pan before slicing into 12–16 bars.

Notes

  • Swirl peanut butter, Nutella, or caramel into the brownie layer before topping with cookie dough.
  • Mix in chopped nuts, toffee bits, or different flavored chips for variety.
  • Make gluten‑free by using a 1:1 gluten‑free flour blend in both layers.
  • Use muffin tins to bake individual brookie cups—reduce bake time by about 5–8 minutes.
  • To slice neatly, cool completely or chill before cutting. Use a sharp knife wiped clean between cuts.
