1 1/4 cup Double-Dutch Dark Cocoa or Dutch-process cocoa
1 teaspoon baking powder
1 teaspoon espresso powder
1 tablespoon vanilla extract
1 cup unsalted butter
2 1/4 cup sugar
1 1/2 cup All-Purpose Flour
2 cup chocolate chips
1) Preheat the oven to 350°F. Lightly grease a 9″ x 13″ pan
2) Crack the 4 eggs into a bowl, and beat them with the cocoa, salt, baking powder, espresso powder, and vanilla till smooth.
3) In a medium-sized microwave-safe bowl, or in a saucepan set over low heat, melt the butter, then add the sugar and stir to combine. Or simply combine the butter and sugar, and heat, stirring, until the butter is melted. Continue to heat (or microwave) briefly, just until the mixture is hot (about 110°F to 120°F), but not bubbling; it’ll become shiny looking as you stir it. Heating the mixture to this point will dissolve more of the sugar, which will yield a shiny top crust on your brownies.
4) Add the hot butter/sugar mixture to the egg/cocoa mixture, stirring until smooth.
5) Add the flour and chips, again stirring until smooth. Note: If you want the chips to remain intact in the baked brownies, rather than melting in, let the batter cool in the bowl for about 20 minutes before stirring in the chips.
6) Spoon the batter into a lightly greased 9″ x 13″ pan.
7) Bake the brownies for about 30 minutes, until a cake tester inserted into the center comes out clean, or with just a few moist crumbs clinging to it. The brownies should feel set on the edges, and the center should look very moist, but not uncooked. Remove them from the oven and cool on a rack before cutting and serving.
