- Grease a 9 inch x 13 inch dark metal pan with softened butter, then line with
parchment paper, leaving overhang on all sides. Grease the parchment with
softened butter.
- Combine :
8 Ounces Semisweet Chocolate, Roughly Chopped;
1/4 Cup Unsweetened Dutch Process Cocoa Powder;
1 Tablespoon Espresso Powder;
in a heatproof liquid measuring cup or medium bowl and set aside.
- Add :
2 1/2 Sticks Unsalted Butter;
to a small saucepan over medium heat and cook until the butter just comes to a
vigorous simmer, about 5 minutes, swirling the pan occasionally.
- Immediately pour the hot butter over the chocolate mixture and let sit for 2
minutes.
- Whisk until the chocolate is completely smooth and melted, then set aside.
- Combine :
2 Cups Granulated Sugar;
1/2 Cup Dark Brown Sugar, Packed;
2 Teaspoons Vanilla Extract;
2 Teaspoons Salt;
6 Large Eggs;
in a large bowl.
- Beat with an electric hand mixer on high speed until light and fluffy, about
10 minutes. It will be similar to the texture of very thick pancake batter.
- With the mixer on, pour in the slightly cooled chocolate and butter mixture
and blend until smooth.
- Position a rack in the middle of the oven and preheat to 350 F or 180 C.
- Sift :
1 Cup All-Purpose Flour;
1/2 Cup Unsweetened Dutch Process Cocoa Powder;
- Use a rubber spatula to gently fold until just combined.
- Pour the batter into the prepared baking pan and smooth the top with a
spatula.
- Bake until lightly puffed on top, about 20 minutes.
- Remove the baking pan from the oven using oven mitts or kitchen towels, then
lightly drop the pan on a flat surface 1 - 2 times until the brownies deflate
slightly.
- Sprinkle with :
Flaky Sea Salt;.
- Return the pan to the oven and bake until a wooden skewer inserted into the
center of the brownies comes out fudgy but the edges look cooked through, about
20 minutes more. The center of the brownies will seem under-baked, but the
brownies will continue to set as they cool.
- Set the brownies on a cooling rack and cool completely in the pan.
- Use the parchment paper to lift the cooled brownies out of the pan.
- Cut into 24 bars and serve immediately. Enjoy!
