Ingredients

Guinness Brownies

3/4 cup Guinness or other stout beer
1 teaspoon instant espresso powder
1/2 cup unsalted butter
3 large eggs
3/4 cup granulated sugar
3/4 cup packed light brown sugar
1 teaspoon vanilla extract
1/2 cup all-purpose flour (spooned and leveled)
1/2 cup unsweetened cocoa powder
1/2 teaspoon kosher salt

Irish Cream Frosting

1/2 cup unsalted butter, softened
1-1/2 cups powdered sugar
1 teaspoon vanilla extract
3-4 tablespoons Irish cream liqueur, room temperature
Green sprinkles for topping, optional

Instructions

Guinness Brownies

Preheat oven to 350F and line a 9-inch square baking dish with parchment paper. Set aside.
Place Guinness in a small saucepan and bring to a simmer over medium-high heat. Reduce heat to medium-low and allow to simmer 5-8 minutes, swirling pan occasionally until liquid is reduced to about half. Remove from heat and whisk in instant espresso powder. Allow to cool slightly.
Place butter in a microwave-safe bowl and microwave 30-60 seconds on high until melted. Use a handheld electric mixer on high (or a lot of elbow grease with a regular whisk) to mix in both sugars well for about 60 seconds of mixing. Mix in eggs, vanilla, and cooled Guinness until smooth.
Add flour, cocoa, and salt to bowl and fold until batter is just combined.
Scrape batter into prepared pan and smooth top. Bake brownies at 350F 25-30 minutes until a toothpick inserted into brownies comes out with moist crumbs sticking to it. Allow brownies to cool completely on a wire cooling rack.

Irish Cream Frosting

Place butter in a large bowl (or a stand mixer fitted with paddle attachment) and use an electric mixer to beat on medium speed 2-3 minutes until creamy.
Add powdered sugar to butter mixture and beat an additional 2-3 minutes until frosting is smooth. With mixer running, add vanilla and just enough Irish cream until frosting is spreadable and creamy.
Frost cooled brownies and top with sprinkles if desired. Serve brownies and enjoy!
