To prepare the frosting: Add dark chocolate chips and butter to a small saucepan on medium heat. Cook until melted, stirring as needed.

Pour the melted dark chocolate mixture into a medium mixing bowl.

Add coffee, 1 tablespoon of milk, powdered sugar and a pinch of sea salt. Use a hand-mixer to mix until incorporated. Mix in an additional 1-2 tablespoons of milk to reach desired consistency.

Once brownies have cooled completely, gently lift the brownies out of the pan by the parchment paper and place on a flat surface.

Spread frosting into an even layer over the brownies. Slice and enjoy!
