Ingredients

Brownies

1 box brownie mix plus ingredients listed on the box to make the brownies typically eggs, oil, and water

Baileys Buttercream

½ cup salted butter softened
1 teaspoon vanilla extract
2½ cups powdered sugar sifted
2 tablespoons Baileys Irish Cream
3 to 4 tablespoons heavy whipping cream

Ganache

⅓ cup heavy whipping cream
2 tablespoons Baileys Irish Cream
1 cup semi-sweet chocolate chips

Instructions

Preheat the oven as indicated on the brownie box. Line an 8x8 square baking pan with parchment paper and set it aside.
Mix the brownie packet with the ingredients listed on the package instructions. (We substituted the indicated ¼ cup water for ¼ cup Baileys Irish Cream liqueur in the brownie recipe.
Bake brownies in the prepared pan according to the package instructions.
Cool brownies completely.
Prepare the buttercream layer by beating together butter, vanilla extract, and powdered sugar in a mixing bowl until combined.
With the mixer running at low speed, pour two tablespoons of Baileys into the buttercream mixture and continue beating.
Add whipping cream 1 tablespoon at a time while continuously beating until a fluffy, smooth frosting forms.
Use an offset spatula to spread the buttercream in an even layer over the top of the cooled brownies.
Place brownies in the freezer while you prepare the ganache.
Combine ⅓ cup heavy cream and 2 tablespoons of Baileys in a heatproof bowl. Microwave for 45 to 60 seconds until the cream mixture is just coming to a simmer.
Pour hot cream over 1 cup of chocolate chips. Let sit for 3 to 4 minutes.
Stir the chocolate mixture until a smooth ganache forms.
Spread ganache over the chilled, frosted brownies.
Allow ganache to set (either on the countertop for 45 to 60 minutes or in the refrigerator for about 15 minutes).
Lift brownies from the tray by the flaps of parchment paper. Cut into even squares and serve immediately.

Notes

The Baileys is not cooked in the buttercream layer, so there is a small alcohol content in the brownies, but it is minimal.
These fudgy brownies are rich, creamy, and so decadent. The Baileys flavor blends seamlessly with the chocolate - we have Baileys in all three layers, but you can, of course, put it in just one or two of the layers. I would recommend including the Baileys in the buttercream frosting layer for the most impact if you don’t want to include it in the other layers.
The brownies need to be all the way cooled before frosting so that they don’t melt the frosting.
If you pop the frosted brownies in the freezer while preparing the ganache, the frosting will firm up so that the ganache can go on smoothly.
