Guinness Brownies

Guinness Brownies are moist and fudgy with a boozy kick mixed in. Made with melted chocolate and topped off with extra chocolate chunks for gooey goodness.

Baking with beer makes for an extra moist Dessert with malty undertones and a rich chocolate taste. Just like Classic Brownies, this recipe comes out fudgy, chewy, and absolutely delicious. It’s the perfect treat to serve to chocolate and beer lovers alike.

GUINNESS BROWNIES

These chocolate brownies are a great way to change up classic brownies. The stout beer adds rich flavor and makes the brownies even more chewy and moist. The beer also plays off the bittersweet chocolate and enhances the sweetness of the dark chocolate in the recipe. 

If you’re looking for treats to serve for St. Patrick’s Day Guinness Brownies are a great way to start. We often think of green desserts for St. Patrick’s like Mint Chocolate Chip Cookies or Mint Chocolate Chip Blondies. These Brownies don’t have the festive color, but the Guinness stout gives it a classic Irish taste, that makes it a must-have recipe.

TOPPINGS

For some easy toppings, you can sprinkle powdered sugar, sea salt, or large grain kosher salt over the top of the brownies. You could also add some green sprinkles to stay in the St. Patrick’s Day theme. Or for even more chocolate make a rich Chocolate Ganache to spread over the brownies.

TIPS FOR MAKING GUINNESS BROWNIES

  • Prep: Start by preheating your oven and prepping your baking pan with cooking spray. If you don’t have a spray to grease the pan, you can always use parchment paper cut to size. 
  • Butter mixture: Add the butter and sugar to your stand mixer and cream until light and fluffy. This should only take about 1-2 minutes. Add the eggs and mix them in. If you don’t have a stand mixer, put the ingredients in a large bowl, and combine them with a handheld electric mixer. 
  • Chocolate: Put the chocolate chunks in a heatproof bowl and microwave in 30-second increments until melted and smooth. Make sure to stir in between microwaving sessions. Slowly add it into the batter and mix the chocolate mixture on the lowest speed. 
  • Dry ingredients: Sift together the flour, cocoa powder, and salt. 
  • Finishing batter: Add in half the flour mixture to the batter and mix it. Then add half the beer, then the rest of the flour, and finish it with the rest of the Guinness. 
  • Cook time: Pour the batter into the prepared pan in an even layer, and sprinkle the remaining chocolate on top. Bake for 25-30 minutes. Keep your eye on the Guinness Brownies and check them at 25 minutes to make sure they don’t burn. To check if they’re done put a toothpick in the center of the brownies. If it comes out just with moist crumbs on the toothpick the brownies are finished baking.

VARIATIONS ON GUINNESS BROWNIES

  • Chocolate Chips: Instead of topping the brownies off with the extra dark chocolate chunks, you can add some chocolate chips to the Batter. Milk chocolate chips, dark chocolate chips, semisweet chocolate chips, or white chocolate chips could all make great additions to the Chocolate Brownies.
  • Coffee: You can use espresso powder to enhance the sweetness of the chocolate in the brownies. Try mixing in 2-3 tablespoons of espresso powder. 
  • Flour: If you want a healthier take on brownies try using whole wheat flour in place of the all-purpose flour. You could also use almond flour, coconut flour, or oat flour for gluten-free Brownies.
  • Sweetener: You can use brown sugar, coconut sugar, or maple syrup to replace the granulated sugar in the recipe.

HOW TO STORE GUINNESS BROWNIES

  • Serve: You can keep baked Brownies at room temperature for 3-4 days. Cover cooled brownies in plastic wrap or aluminum foil to store in the pantry.
  • Store: Kept properly sealed, Guinness Brownies will be good in the fridge for up to 1 week. 
  • Freeze: Put the Brownies in a Ziploc bag or other airtight container to store in the freezer for up to 6 months. Let them thaw in the fridge before enjoying.
