This recipe starts out with your favorite brownies baked in a 9×13 pan and cooled.  You can use a homemade recipe or even a box mix to make it extra easy and quick!

Once cooled, a layer of frosting is spread across the top with lots of yummy Baileys in it.  When making the frosting, you’ll notice that the butter and Baileys don’t exactly blend well at first but don’t worry.Once you add in the powdered sugar, it will become really nice and fluffy.

Make sure your brownies are completely cooled before adding the frosting or the butter will melt.

The ganache is deliciously rich and chocolatey with a boozy Baileys flavor. I find you can definitely taste the Baileys in the ganache.  You’re going to heat the Baileys just until it boils and then pour it over the chocolate and let it sit for a few minutes.

Once you stir, you’ll get a luscious and rich ganache which tops these brownies perfectly.  (This ganache is amazing to top any kind of dessert!).

I always allow my ganache to cool at room temperature for about 30 minutes before refrigerating to help keep that nice shiny finish.  Once completely cooled, you’ll want to store these tightly covered in the fridge.

These Baileys brownies are very rich so we always cut them pretty small.  Store tightly sealed in the refrigerator up to 1 week.

  1. couldnt be easier or better! i never review anything unless its really bad or really awesome. in this case. wow – what an unusual treat. its ultra rich and yes, cheap to make! i say cut the frosting tho – its more than needed to get the effect. could make thick brownies too. any way you look at it they are freaking amazing and you would have to have a zero IQ to mess them up5 stars

  2. I haven’t tasted them yet, but wow, do they smell good! I was going to use the parchment paper to line the pan, but forgot. It didn’t matter. I flipped the pan and they fell right out. I iced them upside down, which made for a nice smooth surface. I’m the worst at spreading icing and this was even easy for me. As an added bonus, my boyfriend had a great time licking the mixers for the icing and the ganache.5 stars

  3. Absolutely fantastic! I followed the recipe for the homemade brownies as well as the Baileys portion and they turned out perfectly. An absolute hit at a birthday party I attended. Will definitely make these again!5 stars
