These Brown Butter Brookies combine the best of both worlds—fudgy brownies and chewy chocolate chip cookies—with the rich, nutty flavor of browned butter. A layered treat that feels both indulgent and comforting.

  • Total Time: 1 hour 45 minutes
  • Yield: 9–12 brookies

Ingredients

  • Brownie batter:
  • 180 g butter
  • 320 g 60% chocolate for melting
  • 120 g all-purpose flour
  • 50 g cocoa powder
  • 180 g granulated sugar
  • 80 g brown sugar
  • 2 g salt
  • 4 eggs
  • 120 g chocolate chunks (optional)
  • Brown butter cookie dough:
  • 85 g all-purpose flour
  • 80 g butter
  • 80 g brown sugar
  • 40 g granulated sugar
  • 1 g salt
  • 1 egg
  • 2 g vanilla extract
  • 70 g chocolate chips
  • Extra chocolate chunks for topping

Instructions

  1. Make the cookie dough: Brown the butter in a saucepan until golden and fragrant. Let cool slightly.
  2. In a bowl, mix browned butter, brown sugar, granulated sugar, and salt. Whisk in the egg and vanilla.
  3. Fold in flour and chocolate chips. Chill dough while making the brownie batter.
  4. Preheat oven to 329°F (165°C). Line an 8×8-inch pan with parchment paper.
  5. Melt the butter and chocolate together using a double boiler. Cool slightly.
  6. In a separate bowl, whisk eggs with both sugars for several minutes until light and thick.
  7. Fold in the melted chocolate mixture, then sift in flour, cocoa powder, and salt. Mix until just combined. Fold in chocolate chunks if using.
  8. Spread half of the brownie batter in the pan. Add pieces of chilled cookie dough over it. Spread remaining brownie batter on top, followed by more cookie dough and extra chocolate chunks.
  9. Bake for 45–55 minutes, until edges are set and a toothpick comes out with moist crumbs.
  10. Let cool completely before slicing into squares.

Notes

  • Chilling the cookie dough helps maintain texture during baking.
  • Don’t overmix the brownie batter once the flour is added.
  • For a shiny brownie top, beat eggs and sugar well until light and ribbony.
  • Top with flaky sea salt for extra flavor contrast.
