Root Beer Whiskey Fudge Brownies – Alcoholic Brownies

Share this...

Last Updated on June 6, 2023 by Leah Hall

Alcoholic brownies. Do I need to say more? Yep, Whiskey.


One of Mrs. Nom’s favorite childhood treats was a chocolate root beer float, so adding a bit of an adult twist to that combination only made sense when we had a bottle of Uncle Bob’s Root Beer Whiskey come into our possession, especially with whiskey being such a great pair with chocolate. Needing a fun brownie dessert recipe for a night with friends, we decided that alcoholic brownies would be the perfect end to a great meal.

Whiskey Brownies

This recipe uses a bittersweet dark chocolate to help balance out the sweetness of the root beer whiskey and enhance the herbal notes making the brownie rich and complex. Topped with a root beer whiskey and chocolate whipped cream frosting, there is just a bit of a bite from the whiskey.

Starting out with a sweet chocolate flavor and finishing with an intense root beer flavor, the light frosting is a perfect topping to the fudgy whiskey brownies.
