Guinness Brownies Recipe

These Triple Chocolate Guinness Brownies are bursting with chocolate flavor! There are three types of chocolate in these brownies – dark chocolate cocoa powder, white chocolate chips, and semi-sweet chocolate chips. Chocolate overload!! What really puts these delicious brownies over the top is the addition of Guinness beer. SO good! The brownies were super rich and fudgy. Perfect in our opinion. This recipe is a must for the Guinness lovers in your house.

How to Make Guinness Chocolate Brownies

These brownies are very simple to make. There is no special equipment and they are ready for the oven in minutes. Spray a 9×13-inch baking pan with cooking spray and line with parchment paper. Whisk flour, dark cocoa powder, and salt together in a medium bowl. Set aside. Melt semi-sweet chocolate, white chocolate chips, and butter in a small bowl in the microwave or small saucepan until melted. In a large mixing bowl, beat sugar and eggs together with an electric mixer on medium-high speed until light and fluffy. Add melted chocolate mixture and beat until just combined. Slowly add dry ingredients, and mix just until combined. Whisk in beer. Pour brownie batter into the prepared baking dish; sprinkle chopped pecans and more semisweet chocolate chips over batter and bake. Allow the brownies to cool completely before cutting into squares. Dust with powdered sugar if desired.

Helpful Tips & Frequently Asked Questions

I topped the brownies with some chopped pecans. You can certainly leave them off if you aren’t a fan of nuts in your brownies.
- If you don’t like pecans, you could use peanuts or walnuts.
You can melt the chocolate in the microwave, in a small saucepan on the stovetop or in a double boiler over low heat.
Can cut the recipe in half and bake in a 9-inch baking pan.
Can use any chocolate chip combination: white chocolate chips, semi-sweet chocolate chips, milk chocolate chips or dark chocolate chips all work great.
I used Hershey’s Special Dark cocoa powder. You can substitute regular cocoa powder if you prefer.
Do the brownies taste like beer? NO! You would never know that there is beer in the brownies.
How long do brownies last? Cut brownies will keep 1 to 2 days in an airtight container. Uncut brownies will keep up to 4 days wrapped tightly in plastic wrap.
Can brownies be frozen? Yes! Bake the brownies and let them cool completely. Wrap in plastic wrap and aluminum foil. I suggest freezing the brownies uncut. The brownies will keep up to 3 months. Thaw and cut into squares before serving.
