Guinness Brownies with Guinness Frosting
Introduction
These Guinness Brownies with Guinness Frosting are a celebration of rich chocolate and the malty, slightly bitter warmth of stout. The brownies have a fudgy, dense interior with a crackly top, while the frosting is silky and lightly boozy, carrying that stout character through to every bite. You will notice deep cocoa notes, a whisper of roasted coffee from the optional espresso powder, and a creamy finish from the butter-sweet frosting. These brownies are ideal for gatherings like St. Patrick’s Day, cozy weekend baking, or when you want an elevated treat with grown-up flavor. If you love layered chocolate desserts, you might also enjoy this chocolate orange layer cake with ganache for another show-stopping option.
Ingredients
- 1 (11.2–12-ounce) bottle Guinness Draught Stout beer, to be reduced for concentrated flavor in both batter and frosting.
- 3/4 cup unsalted butter, used to melt with chocolate for a rich, glossy base.
- 2 (4-ounce) bars semi-sweet chocolate, coarsely chopped, provides deep chocolate intensity.
- 1 and 1/4 cups granulated sugar, sweetens the brownies and helps create a crackly top.
- 3 large eggs, at room temperature, for structure and fudgy texture.
- 1 teaspoon pure vanilla extract, adds warmth and rounds the chocolate flavors.
- 1 cup all-purpose flour, the main dry ingredient for body and chew.
- 1/2 teaspoon salt, balances sweetness and enhances chocolate depth.
- 1/2 teaspoon espresso powder (optional), amplifies chocolate notes without tasting like coffee.
- 1/2 cup unsalted butter, softened to room temperature for the frosting, gives creaminess.
- 2 cups confectioners’ sugar, for a smooth, sweet frosting base.
- 2–3 tablespoons reduced Guinness, to flavor and thin the frosting to spreadable consistency.
- 1 teaspoon espresso powder (for frosting), a hint of depth in the frosting.
- 1/2 teaspoon pure vanilla extract (for frosting), brightens the frosting flavors.
- 1/4 teaspoon salt (for frosting), keeps the frosting from tasting overly sweet.
Step-by-Step Instructions
- Reduce the Guinness by bringing the full bottle to a boil in a small saucepan over medium-high heat, then lower to a simmer and cook until reduced to 2/3 cup. Let it cool completely before using. Tip: watch carefully as it simmers to avoid scorching.
- Preheat the oven to 350°F (175°C) and grease a 9-inch square baking pan with a thin layer of butter or nonstick spray.
- In a microwave-safe bowl, melt 3/4 cup unsalted butter and the coarsely chopped semi-sweet chocolate together in short bursts, stirring between sessions until smooth. You can also use a double boiler if preferred.
- Whisk in the granulated sugar and 1/2 cup of the reduced Guinness into the melted chocolate mixture until the batter looks glossy and well combined.
- Add the 3 large eggs and 1 teaspoon pure vanilla extract, then whisk until everything is incorporated and smooth.
- Add 1 cup all-purpose flour, 1/2 teaspoon salt, and 1/2 teaspoon espresso powder if using. Whisk gently until just combined; do not overmix to keep the brownies fudgy.
- Pour the batter into the prepared pan and bake for 32 to 35 minutes, until a toothpick inserted into the center comes out with a few moist crumbs attached. For a fudgier center, aim for the lower end of the time range.
- Cool the brownies completely in the pan on a wire rack before frosting. Cooling helps the frosting spread smoothly and prevents it from sliding off.
- For the frosting, beat the 1/2 cup softened unsalted butter until smooth using a mixer or sturdy spatula.
- Gradually mix in the 2 cups confectioners’ sugar, then beat in the remaining reduced Guinness (2 to 3 tablespoons), 1 teaspoon espresso powder, 1/2 teaspoon pure vanilla extract, and 1/4 teaspoon salt until you reach the desired spreading consistency. Add the Guinness a little at a time to control thickness.
- Once the brownies are cool, spread the Guinness frosting evenly over the top. Cut into squares and store at room temperature. Tip: use a sharp knife wiped clean between cuts for neat squares.

Tips, Storage & Variations
- Small tips: Reduce the Guinness slowly and keep an eye on the pan to avoid reducing too far. Let the reduced stout cool before adding to the batter to prevent cooking the eggs.
- Storage: Store frosted brownies in an airtight container at room temperature for up to 3 days. For a slightly firmer frosting, chill briefly before slicing.
- Freezing: Wrap individual squares tightly in plastic wrap and place in a freezer-safe container for up to 3 months. Thaw at room temperature before serving.
- Flavor variations using existing ingredients only:
- Omit the espresso powder for a milder chocolate-forward brownie.
- Double the espresso powder in both batter and frosting for a bold mocha twist.
- Use 3 tablespoons of reduced Guinness in the frosting instead of 2 for a stronger stout note.

FAQ
Q: Can I use a different stout instead of Guinness?
A: Yes, any draught-style stout will work, but flavors will shift slightly based on the stout profile.

Q: Can I skip the frosting?
A: Yes, these brownies are delicious unfrosted and will be less sweet without it.
Q: How do I know when brownies are done?
A: Insert a toothpick; it should come out with a few moist crumbs for fudgy brownies.
Q: Can I make the batter ahead of time?
A: You can prepare batter and refrigerate it for up to 24 hours, but allow it to come to room temperature before baking.
People Also Ask
