Good brownies don't come from boxes, they come from the heart. By that I mean, lots of good butter, and made completely homemade.
3/4 cup (170g) butter, melted
1.25 cups (282g) granulated sugar
1/2 cup (73g)flour
3/4 cup (80g) cocoa pow
1/2 teaspoon (3g) salt
1.5 tsp (2g) instant espresso
1 tablespoon (10g)vanilla extract
4oz (113g) dark chocolate chopped
Top with flakey salt
Whisk flour, cocoa powder, sea salt and espresso powder and set aside.
In medium large bowl add sugar, melted unsalted butter, room temperature egg one at a time, and 1 tbsp (10 g) vanilla extract.
Mix in flour mixture with the wet ingredients until nice, smooth and glossy.
Fold in dark chocolate.
Add mixture to greased parchment lined 8x8 baking pan
Bake at 350 degrees F, 175 C 35-40 minutes or until toothpick inserted comes out clean. Let cool to room temp before cutting.
Use a metal pan over glass when baking to make cutting friendlier.
Top with flakey salt.
