Fire up your oven to the temperature mentioned on the brownie box. Prepare an 8x8 pan with parchment paper and keep it ready. Mix the brownie box contents with the package-listed ingredients. (For a richer taste, you can swap out the noted ¼ cup water for ¼ cup of Baileys.) Bake as directed and let them cool fully after baking.

In a mixing bowl, stir together the softened butter, vanilla, and the powdered sugar. With the mixer on, slowly add 2 tablespoons of Baileys. Gradually mix in the whipping cream—1 tablespoon at a time—until your frosting is light and fluffy.

Use a spatula to coat the chilled brownies with the buttercream evenly. Pop the frosted brownies into the freezer while working on the ganache—it’ll make spreading the ganache much easier.

In a microwave-safe bowl, combine ⅓ cup of heavy cream and 2 tablespoons Baileys. Heat it up for about 45 to 60 seconds—just until the cream starts bubbling. Pour it over the chocolate chips and let the mix sit for a few minutes. Then, stir it all up until nice and smooth.

Pour the finished ganache over the top of the hardened frosting layer. Let it set—either on the counter for an hour or chill it in the fridge for about 15 minutes. Lift the brownies out with the parchment paper edges, slice into uniform squares, and serve right away.
