These fudgy, boozy Baileys brownies are the perfect grown-up dessert. With a layer of Irish cream frosting and Irish cream ganache on top!
I don’t typically bake with alcohol, but Baileys Irish Cream is where I’ll happily make the exception. So today, we’re making a triple-layered brownie that’s frosted with fluffy Baileys frosting and has a layer of Baileys chocolate ganache on top. They’re rich, decadent, and definitely adults only.
Warning – these are very rich and you can definitely taste the Baileys.
The bottom layer of the brownies is your classic, homemade brownie recipe for a 9×13 inch pan. You can easily use a box brownie mix if you want to save time (simply follow the package instructions), or even use your own favorite recipe. Just make sure that your brownies aren’t overly gooey or overly sweet. You want them to be sturdy enough to support the layers on top, and not too sweet since we’re adding frosting and ganache.
The middle layer is a fluffy Irish cream buttercream made with butter, powdered sugar and Baileys. Make sure that your butter is softened to room temperature (but not beginning to melt) and that you sift the powder sugar so there are no lumps.
Pro Tip: The brownies should be fully cooled before frosting. Otherwise, the frosting can melt. Place the frosted brownies back in the fridge for the Baileys buttercream to become a thick layer.
Last but not least, chocolate ganache goes on top. Chocolate ganache is typically made with chocolate and heated cream, but we’re using Irish cream instead. If you prefer a milder Baileys flavor, you could substitute the Baileys for heavy cream, or simply use half Baileys and half heavy cream.
Pro Tip: These brownies should be stored in the fridge. Cold brownies are also easier to cut.
Because these brownies are rich, you only need a small piece. But if you love fudgy, rich, desserts, or a splash of Irish cream in your coffee, you should definitely try these Baileys brownies.
