Ingredients
Scale
- 3oz (1/4 Cup + 2 Tablespoons) Guinness, reduced from 6oz (3/4 Cup)
- 1oz (2 Tablespoons) Unsalted Butter
- 250 Grams (1 1/4 cups) Granulated Sugar
- 90 Grams (3/4 cups) Dutch-process Cocoa Powder
- 3.5oz (scant 1/2 cup) Vegetable Oil
- 2 Teaspoons Pure Vanilla Extract
- 1 Large Egg Yolk, at room temperature
- 1 Large Egg, at room temperature
- 1/8 Teaspoon Baking Soda
- 1/2 Teaspoon Salt
- 1 Tablespoon Cornstarch (Cornflour)
- 75 Grams (scant 2/3 cup) All-Purpose Flour (Plain Flour)
- 2oz (1/4 cup) Chocolate chips, chunks, or bars chopped
- 1/2 Recipe of Baileys Swiss Meringue Buttercream
Instructions
- In a large pot, add the full 6oz of Guinness and simmer over medium heat for 5-10 minutes until reduced by 50%, leaving 3oz of concentrated Guinness flavor.
- Add the unsalted butter and granulated sugar to the reduced Guinness. Cook on low heat until the butter melts and the sugar fully incorporates. Let cool for 5 minutes, then transfer the mixture to a separate bowl.
- Stir in the Dutch-process cocoa powder and vegetable oil to the cooled Guinness mixture until fully combined and smooth.
- Add the vanilla extract, large egg, and large egg yolk to the cocoa mixture, whisking thoroughly to combine.
- Mix in baking soda, salt, and cornstarch. Gently fold in the all-purpose flour using a spatula, stirring just until no flour streaks remain.
- Fold in the chopped chocolate chunks or chips gently.
- Pour the batter into a 9-inch square pan lined with foil and greased heavily with non-stick spray. Bake in a preheated 350°F (180°C) oven for 25-27 minutes until a toothpick inserted comes out with moist crumbs.
- Allow brownies to cool completely. Using an offset spatula, pipe or spread swirls of Baileys Swiss Meringue Buttercream on top.
- Cut brownies into 9 to 16 pieces depending on desired serving size. Store at room temperature unless in a warm environment, then refrigerate to maintain texture.
