Classic Guinness Brownies
Just when you thought brownies couldn’t get any better, along comes a stout-infused version that’s rich, fudgy, and has a subtle malty kick. Trust me, your taste buds are in for a party!
Serving: 16 | Prep Time: 15 minutes | Cooking Time: 25 minutes
Ingredients
- Butter (unsalted) – ½ cup (1 stick)
- Semi-sweet chocolate (chopped) – 4 oz
- Granulated sugar – 1 cup
- Large eggs – 2
- Vanilla extract – 1 tsp
- Guinness stout – ½ cup
- All-purpose flour – ¾ cup
- Unsweetened cocoa powder – ¼ cup
- Salt – ½ tsp
Instructions
- Preheat oven to 350°F. Line an 8×8-inch baking pan with parchment paper, leaving overhang on two sides.
- In a large microwave-safe bowl, combine butter and chopped chocolate. Microwave in 30-second bursts, stirring after each, until completely melted and smooth. Let cool slightly.
- Whisk in sugar until well combined, then whisk in eggs one at a time, followed by vanilla extract. Stir in Guinness stout until fully incorporated — the batter will look thin and glossy.
- In a separate bowl, sift together flour, cocoa powder, and salt. Gently fold the dry ingredients into the wet until just combined. Tip: Overmixing leads to cakey brownies — stop as soon as no streaks of flour remain.
- Pour the batter into the prepared pan and spread evenly. Bake for 25–30 minutes, until the edges are set and a toothpick inserted into the center comes out with a few moist crumbs. Tip: For extra gooeyness, pull them out at 25 minutes; for more structure, go to 30.
- Transfer the pan to a wire rack and cool completely before lifting out by the parchment. Tip: Patience is key — cutting warm brownies makes a crumbly mess. Cut into 16 squares and serve.
Bite into one of these brownies and you’ll get that incredible fudgy texture with a hint of roasted malt. They’re perfect for St. Patrick’s Day or any time you want a grown-up twist on a classic. Stack ’em on a plate, dust with powdered sugar, or serve with a scoop of vanilla ice cream for pure indulgence.

- Sift flour, cocoa powder, and salt into the bowl. Fold until just combined—no white streaks. (Tip: Overmixing leads to cakey brownies; we want fudgy.)

- Make caramel: In a heavy saucepan over medium heat, melt sugar, stirring constantly until it turns amber, about 6-8 minutes. (Tip: Watch closely; sugar burns fast.)
- Remove from heat and whisk in butter pieces until melted. The mixture will bubble.
- Slowly pour in heavy cream while whisking—it will steam. Whisk until smooth. Stir in ½ tsp sea salt flakes.
- Let caramel cool 5 minutes, then dollop spoonfuls over the brownie batter. Use a knife to swirl.
- Sprinkle flaky sea salt over the top.
- Bake for 30-35 minutes, until a toothpick inserted in center comes out with moist crumbs. (Tip: For fudgier brownies, underbake slightly.)

Ingredients
For the brownie base

- Remove from heat. Add 1 cup dark chocolate chips; let sit 1 minute, then stir until smooth and glossy.
- In a large bowl, whisk together 1 cup sugar, 2 eggs, and 1 tsp vanilla. Slowly pour the chocolate mixture into the egg mixture, whisking constantly.
- In a small bowl, sift together 3/4 cup flour, 1/4 cup cocoa powder, and 1/2 tsp salt. Fold into wet ingredients until just combined—don't overmix. (Tip: Overmixing develops gluten and makes brownies cakey, not fudgy.)
