A perfectly balanced brownie (not too fudgy, not too cakey) with a light textured chocolate buttercream frosting.Also, this recipe halves well. To make a half batch, halve all the ingredients and bake in an 8 inch square pan.
⅔cupunsalted butter, melted and still hot(150 grams)
½cupboiling water
2cupsgranulated sugar(400 grams)
2largeeggs
1 ⅓cupsall-purpose flour(170 grams)
1teaspoonvanilla extract
½teaspoonsaltuse ¼ tsp if using salted butter
1cupHershey’s special dark chocolate chips(170 grams)
Frosting
6tablespoonsunsalted or salted butter, softened(84 grams)
2 ⅔cupspowdered sugar
½cupnatural unsweetened cocoa powder(40 grams)
⅓cupwhole milk(75 grams)
1teaspoonvanilla extract
Instructions
Preheat oven to 350°F. Line a 13x9 inch metal pan with nonstick foil or parchment paper.
Stir together cocoa and baking soda in large bowl. Stir in ⅓ cup of the melted butter, then add boiling water and stir until mixture thickens. Stir in sugar, eggs and remaining ⅓ cup butter.
Add flour, vanilla and salt; blend completely. Stir in chocolate chips. Pour into prepared pan.
Bake 35 to 40 minutes or until brownies begin to pull away from sides of pan. Cool completely in pan on wire rack.
To make the frosting, beat butter in medium bowl. Add powdered sugar and cocoa alternately with milk, scraping sides of the bowl often. Beat in vanilla. Spread across cooled brownies.
This last step is optional, but I recommend chilling the brownies, then lifting from the pan and slicing them while they are very cold.
Notes
Natural cocoa powder is more acidic than Dutch or "Dark" cocoa powder, and its acidity works in conjunction with the alkaline baking soda to affect the leavening process. You could get away with using dark or Dutch, but the brownies may or may not rise quite as much or they may just have a different texture. For the flour, make sure not to use too much. If you weigh out 6 oz you'll be fine. If you don't have a scale and are measuring by volume, be sure to aerate and stir the flour and measure it without packing it into to cup. Too much flour can make brownies dry.
