Preheat your oven to 350°F. Butter up a 9x13 inch metal pan, line it with parchment paper, and make sure the paper hangs over the edges—it makes taking the brownies out way easier.

Gently heat the butter on low in a little saucepan, let it melt fully, then take it off the burner. Toss in the chopped chocolate and let it sit for a minute. Stir until silky smooth. If it’s not fully melted, put it back on the stove for 10 seconds, then set to cool slightly.

Grab a small bowl and sift your cocoa powder, espresso powder, and flour together. Put this to one side for later.

Using an electric mixer, beat together the eggs, white and brown sugars, salt, and vanilla for about 4-5 minutes. You want the mix to look thick, frothy, and a bit pale.

With a spatula, fold the cooled chocolate blend into the whipped eggs. Work carefully so you don’t lose that light texture. Afterward, gently add the dry mix bit by bit.

Spoon the brownie batter into your parchment-lined pan and smooth out the top. Pop it in the oven for about 25 minutes. The surface should look cracked but still feel soft inside. Let them cool fully in the pan on a rack.

In a medium bowl, start by briefly mixing mascarpone and cream. Toss in the sugar, espresso powder, salt, and vanilla bean paste. Beat the mix together until soft peaks appear. Should take just a minute or two.

Once your brownies are completely cool, spread the light coffee cream on top. Use a sifter to sprinkle cocoa powder all over. Slice into squares and either dig in immediately or refrigerate till later.
