Mix instant coffee into 2 tablespoons of heavy whipping cream and let it sit. Whip the butter with a hand or stand mixer until it gets super fluffy. Gradually mix in powdered sugar until it looks smooth, then pour in your coffee-cream blend. Toss in more cream if you want the icing thinner or easier to spread.

Let brownies chill in the pan, right on a cooling rack. Make sure they're not warm before you add the frosting.

Dump the mixture in your ready pan and spread it out. Pop it in the oven for 30 to 35 minutes. Check with a toothpick—if it mostly comes out clean, you're good.

Whisk together the melted butter, sugar, eggs, and vanilla in a big bowl until it all looks the same.
