Festive foods take on new meaning when made with serious beer, like these delicious chocolate brownies that are made even moister with the addition of a classic Irish stout.

This tasty recipe comes our way from The Kitchen of Chef Dennis Prescott and it uses Guinness Draught, a nitro-infused 4.2% ABV Dry Irish Stout which was developed in 1959, to mark Arthur Guinness signing his 9,000-year lease and 200 years of groundbreaking brewing.

And the Guinness Stout is the secret ingredient behind these uber-moist brownies that always taste fresh.

So let’s do this!

Guinness Brownies  

Ingredients:

  • 1 ¼ cups all-purpose flour
  • ⅓ cup unsweetened cocoa powder
  • ½ teaspoon sea salt
  • 12 ounces finely chopped bittersweet chocolate
  • 6 tablespoons unsalted butter, cut into 1-inch cubes
  • ¾ cup sugar
  • 4 large eggs, at room temperature
  • 1 teaspoon vanilla extract
  • 1 ¼ cups Guinness Draught
  • 4 ounces milk chocolate chips
  • 4 ounces white chocolate chips

 

Instructions:

Step 1

Pre-heat an oven to 350 degrees F, and lightly grease a 9×9 pan with butter, then line with parchment paper.

Step 2

In a medium bowl, whisk the flour, cocoa powder, and salt, and set aside. Add the bittersweet chocolate and butter to a medium glass bowl and melt. Add the sugar, and whisk well to combine. Whisk in the eggs, one at a time, then add the vanilla.

Step 3

Whisk in ½ of the flour mixture until fully incorporated, then add the remaining mixture, and whisk until just combined (be sure to not over whisk). Flour in about ½ of the chocolate chips.

Step 4

Transfer the brownie mixture to the prepared pan, then top evenly with the remaining chocolate chips. Bake for about 25 – 30 minutes, or until just set in the center (they should still be underbaked and will firm up as they cool). Remove from the pan and transfer to a cooling rack, without cutting the brownies.

Step 5

Cool completely, then transfer to the fridge and chill for 2 hours before cutting into brownies (if you can wait that long). Serve with a pint of Guinness Draught, and enjoy.
