How to Make Guinness Brownies

This recipe is the best way to upgrade your regular batch of brownies. They’re so rich and delicious that everyone will be coming back for more! Here’s how to make them:

Brownies

1. Prep and Whisk Wet Ingredients: Preheat the oven to 350ºF. Spray a 9 x 9 x 2-inch metal baking pan with nonstick cooking spray and line it with parchment paper. Leave a 1-inch overhang on either side, then set aside. In a large bowl, whisk together the oil, butter, Guinness, and sugar until well combined.
2. Mix in Eggs and Vanilla: Add in the eggs and vanilla and whisk until combined.
3. Whisk Dry Ingredients: In a separate bowl, whisk together the flour, salt, baking powder, unsweetened cocoa powder, and dark cocoa powder.
4. Combine Wet and Dry Ingredients: Mix the flour mixture into the Guinness mixture until just combined.
5. Add Chocolate Chunks: Gently stir in the chocolate chunks.
6. Bake: Pour the batter into the prepared pan and bake for about 35-40 minutes or until a toothpick comes out clean. If you like your brownies more on the gooey side, bake for 30-35 minutes.

Ganache

7. Chocolate Chips: Meanwhile, prepare the Guinness ganache by adding the chocolate chips to a large bowl.
8. Make Ganache: Heat the heavy whipping cream and Guinness in the microwave for 1 minute and 30 seconds. Then, pour it over the chocolate chips.
9. Whisk and Chill: Let it sit for 2-3 minutes before you whisk until the chips have melted, everything is combined, and it looks glossy. Cover and chill for 15-30 minutes.
10. Beat: Use a hand mixer to beat the ganache until light and fluffy.
11. Frosting: Frost over the top of the completely cooled Guinness brownies. Slice into bars and serve.

Beer in Brownies? Here’s What to Expect!

Guinness beer is the secret ingredient! You won’t believe how rich and flavorful it makes these brownies.

• Does it taste like beer? The Guinness adds a malty flavor that enhances the chocolate, but the beer taste itself isn’t overpowering. Some people notice it more than others, but it mostly deepens the richness of the chocolate.
• Do you have to use Guinness? No! While Guinness stout beer is my top recommendation, you can use another dark stout if needed. It can be hard to find sometimes, so use what you can find.
• Can kids eat Guinness brownies? Since the ganache isn’t baked, it retains its alcohol content. If serving minors, replace the Guinness in the ganache with heavy whipping cream for a kid friendly option. If you want to skip the beer altogether, follow my ultimate brownie recipe.
