Step 1: Heat oven to 325F (Pyrex).
Step 2: Spray an 8-inch square baking dish with nonstick spray.
Step 3: If desired, line the pan with a piece of parchment, leaving an overhang on two sides; spray the parchment with nonstick spray.
Step 4: In a small saucepan, melt the butter and chopped chocolate with the coffee powder, stirring occasionally; remove from heat.
Step 5: With an electric mixer, beat the eggs and sugar on medium-high until light and fluffy.
Step 6: Reduce speed to low and mix in the melted chocolate mixture, then the flour and salt just until incorporated. Fold in the nuts and chocolate chips.
Step 7: Spread the batter in prepared pan and bake 25-30 minutes.
Step 8: Cool completely in the pan.
Step 9: COCOA FUDGE GLAZE:
Step 10: Melt butter in a medium sized saucepan over low heat.
Step 11: In same saucepan, stir in cocoa, salt, powdered sugar, optional instant coffee powder, and milk. Whisk constantly over lowest heat for about a minute.
Step 12: Remove from heat and add extract; whisk well.
Step 13: Whisk until smooth and creamy, only adding additional powdered sugar if more of a frosting-like consistency is desired. Glaze will set up as it cools!
Step 14: Garnish with additional chopped nuts, if desired.
Step 15: Cool completely; holding both sides of the paper overhang, lift the uncut brownies out of the pan, transfer to a cutting board, and cut into 16 squares.
