The Best Brownies Ever

Add the flaxseeds, espresso, and water to a large bowl. Mix and set aside.

Line an 8-inch light metal square metal cake pan with parchment paper and preheat the oven to 350°F (180°C)*.

Returning to the large bowl, add the granulated sugar, brown sugar, and vanilla extract. Mix well, then set aside.

Fill a saucepan less than halfway with water and bring to a boil. Place a large heat-safe bowl on top of the saucepan.

Add the chocolate and butter, mixing until it's all melted. Then add this melted mixture to the large bowl and mix.

Place a sieve over the bowl and sift in the flour, cocoa powder, baking powder, and salt. Mix until partially combined.

Stir in the chopped chocolate, reserving a small amount to sprinkle on top, if desired. Mix until just combined, being careful not to overmix.

Transfer the batter to your prepared baking dish and smooth it out evenly.

Top the brownie with the reserved chopped chocolate.

Bake in the oven on the middle rack for 30 to 35 minutes**.

Let the brownie cool off completely, sprinkle over some flaked sea salt if desired, and cut into squares. Enjoy!
