unsalted butter
milk powder (optional)
whiskey or water
dark brown sugar
salt
eggs
vanilla extract
all-purpose flour
chopped chocolate or chocolate chips

brown sugar

vanilla extract
coffee extract or instant coffee

Directions
Preheat your oven to 180°C (350°F) and line your baking pans with parchment paper, leaving some overhang for easy removal.
To make the brown butter, melt butter over medium heat, add milk powder, and whisk continuously until the milk solids turn a deep golden brown. Remove from heat and let it cool slightly before carefully adding whiskey or water.
For the cookie layer, mix the warm brown butter with sugar and salt. Add eggs and vanilla, then beat until the mixture becomes lighter and slightly thickened. Fold in flour and chocolate chunks, then set aside.
For the brownie layer, melt butter, chocolate, and sugars together in short intervals, stirring until smooth. Add vanilla and dissolved coffee, then mix in eggs and beat until thick and pale. Sift in flour and cocoa powder, and gently fold until just combined.
To assemble, alternate scoops of brownie and cookie batter in the pan and swirl gently, or layer brownie first and then cookie dough on top.
Optionally sprinkle sea salt flakes and extra chocolate on top.
Bake for 35–40 minutes until a toothpick inserted in the center comes out with a few moist crumbs. Allow to cool completely before slicing into bars.
