In a small saucepan, melt the unsalted butter over low heat until fully liquefied. Avoid browning the butter.
Add the unsweetened cocoa powder to the melted butter and whisk constantly until the mixture is smooth and lump-free, about 1 minute.
Stir in the brewed espresso or strong coffee until fully incorporated with the cocoa-butter mixture. Remove from heat.
Gradually whisk in the powdered sugar, a little at a time, until the icing becomes thick and creamy.
Stir in the vanilla extract and a pinch of salt to round out the flavor.
Let the icing cool slightly before spreading it over cooled brownies. It will thicken further as it cools.
Spread the icing evenly over the brownies using an offset spatula or the back of a spoon. Allow the frosting to set for 10–15 minutes before slicing and serving.
