Ingredients You’ll Need
Here’s everything you’ll need to make these rich brownies:
- 4 large eggs
- ¾ cup salted butter, melted
- ½ cup vegetable oil
- 2½ cups white sugar
- ½ cup powdered sugar
- 1 cup unsweetened cocoa powder
- 2 cups all-purpose flour
- 10 oz semi-sweet chocolate chips
- ½ teaspoon vanilla extract
- 1½ cups Guinness stout or family-safe substitute
Family-Safe Substitute Options
To keep this recipe suitable for everyone, replace the Guinness with one of the following (same amount):
- Strong brewed coffee, cooled (best chocolate depth)
- Chocolate milk (slightly sweeter, kid-friendly)
- Milk + 1 teaspoon molasses (malty richness)
How to Make Guinness Chocolate Brownies (Step-by-Step)
Step 1: Prep the Pan
Preheat your oven to 350°F (175°C). Line a 9×13-inch baking pan with parchment paper or lightly grease it.
Step 2: Mix the Wet Ingredients
In a large bowl, whisk together melted butter, vegetable oil, white sugar, and powdered sugar until smooth and glossy.
Step 3: Add Eggs and Vanilla
Whisk in the eggs one at a time, beating well after each addition. Stir in the vanilla extract.
Step 4: Build the Chocolate Base
Add the cocoa powder and mix until fully incorporated. The batter will become thick and dark—this is where the deep chocolate flavor starts.
Step 5: Add Dry Ingredients
Gently fold in the flour just until combined. Avoid overmixing to keep the brownies fudgy.
Step 6: Finish the Batter
Stir in the chocolate chips, then slowly pour in the Guinness or chosen substitute. Mix gently until smooth.
Step 7: Bake
Pour batter into the prepared pan and smooth the top. Bake for 35–45 minutes, until the edges are set and a toothpick inserted in the center comes out with moist crumbs.
Step 8: Cool and Slice
Allow brownies to cool completely before slicing for clean, perfect squares.
Tips & Variations
- For extra fudgy brownies, slightly underbake by 2–3 minutes
- Add chopped walnuts or pecans for texture
- Sprinkle flaky sea salt on top before baking
- Use dark cocoa powder for an even richer flavor
- Chill brownies before cutting for bakery-style slices

- Room temperature: up to 3 days (airtight container)
