Bailey’s brownies are layered with Bailey’s buttercream frosting and chocolate ganache. They are a delicious treat for St. Patrick’s Day!
Bailey’s brownies have the most superb layers. It starts with a thick, fudgy brownie, which is topped with soft Bailey’s buttercream frosting and decadent chocolate ganache. The brownies have a sprinkle of espresso in the batter to bring out the chocolate flavor and complement the Bailey’s frosting. The chocolate ganache is given time to set so it keep its form as you slice and serve the brownies.
Why this recipe works: To start, this uses my fudgy brownie recipe, which is a fan favorite and guarantees and thick, chewy brownie. Allowing the brownies to cool before frosting sets up the layers for success. The chocolate ganache is the perfect consistency to harden slightly on top of the frosting.

Helpful tips for this recipe
To start, read through my brownies recipe post for how to make fudgy, chewy brownies. Avoid overbaking the brownies since you want them fudgy. Let the brownies cool completely before frosting, otherwise the frosting will melt. For the Bailey’s frosting, make sure your ingredients are at room temperature to achieve the best frosting consistency. To make the ganache, use high quality chocolate such as Ghirardelli or Bakers Chocolate. This will make the chocolate easier to melt and smoother consistency (check out my chocolate ganache post for more tips). Let the ganache fully set and chill before cutting and serving the brownies.
Frequently Asked Questions
Yes, in a pinch, boxed brownies may be used for this recipe. Many people prefer Ghirardelli brownie mix.
The butter was too warm when the frosting was made or you are baking in a warm climate. Room temperature butter is 70 degrees F. It should be soft and cool to the touch, but not greasy. To fix this, put the mixing bowl in the refrigerator for 15 to 20 minutes, beat the frosting for 5 seconds and use.
The chocolate is not high quality or the ganache temperature is too hot. The heavy cream and Bailey’s should be scalding hot, not boiling. The liquid will have small bubbles around the edges of the saucepan when it’s the right temperature.
Brownies will last one week when covered and stored in the refrigerator.
Yes, if you can find nonalcoholic Bailey’s, it may be used in this recipe. You can also make your own nonalcoholic Irish cream.
