Guinness Brownies with Cream Cheese Frosting Drizzle

-1 Preheat the oven to 350°F. Line a 9"x9" square baking pan parchment paper and spray with cooking spray (or forgo the parchment paper, and butter and flour the dish.) Set aside.
-1 In a large bowl, combine ¾ cup of dark chocolate chunks and the butter. Heat the mixture in the microwave in 30 second increments, removing the bowl and stirring after each session.
-1 Once all the chocolate is melted, measure in the sugars and vanilla. Stir until combined.
-1 Crack the eggs in a small bowl, and break the yolks using a fork. Pour into the chocolate and sugar mixture, stirring until combined.
-1 In a medium-sized bowl, combine the flour, cocoa powder and salt.
-1 Sprinkle the dry ingredients into the wet ingredients, stirring, then add the Guinness. Stir until there are no longer lumps, and the mixture is well combined.
-1 Pour the brownie batter into the prepared baking dish. Sprinkle the additional ¾ cup of dark chocolate chunks on top of the brownies.
-1 Bake for 40 to 50 minutes, or until the edges are firm and an inserted toothpick comes out clean.
-1 While the brownies bake, combine the frosting ingredients with a hand mixer, and mix until smooth.
-1 Let cool for 20-30 minutes before drizzling with the cream cheese frosting, then slicing.
-1 Enjoy with a glass of milk... or a pint of Guinness.
