These walnut brownies are what proper brownies should be — crusty and shiny on top, fudgy in the centre, and bursting with walnuts and chocolate chips in every bite.
Preheat oven to 325F. Line a 9x13 baking pan with parchment paper with slight overhang on each side. Set aside.
In a large bowl, whisk ¾ cup cocoa powder and ½ tsp baking soda. Whisk in ⅔ cup melted butter until smooth. Then whisk in ½ cup espresso until thick and incorporated.
Add 1 ½ cups sugar, ½ cup brown sugar, 2 tsp vanilla, 2 eggs and a pinch of salt. Stir until shiny and smooth.
Add 1 ⅓ cups flour, your chocolate chips and walnuts and gently stir until just combined. Don't overstir.
Transfer the batter to your prepared pan and bake for 30-40 minutes or just until the sides are starting to pull away from the pan and a toothpick inserted in the centre comes out with minimal crumbs.
Let cool in the pan completely before cutting into squares.
