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. OMG these brownies are amazing, can’t wait to take them to work tomorrow for everyone to try. These will definitely be on this Christmas baking list. Thank you so much for sharing this recipe. 

  2. I put the frosting and ganache over Delish’s Death By Chocolate Brownies. It was a huge hit with everyone. The next time I will probably omit the Bailey’s from the ganache as my own personal preference.5 stars

  3. So something I learned in France is that there is something big called Eurovision. It was an experience I can say I attended in full force. Along with that, I whipped up a batch of these to come along with me. They were a hit.5 stars

  4. I made this yesterday with modifications for it to be gluten free and dairy free. It was delicious! Thanks for sharing this recipe.

    If anyone cares about the substitutions….I used the Betty Crocker gluten free brownie mix (x2 so they would still be thick enough), earth balance vegan buttery sticks, Baileys Almande, coconut cream instead of heavy cream, and Enjoy Life chocolate chips.

  5. I’ve just made the frosting and put only 2 cups of powdered sugar and it’s still sweet enough. I added half a tub of marscapone and some ground almond for texture to the frosting. Thanks for the recipe it looks delicious!

  6. Once the ganache has set for 30 minutes, should you cut them before refrigerating? So far they look wonderful!!

    1. The ganache gets firm once it cools. You want the ganache warm for pouring (and the Baileys frosting cooled).

  7. Do these have to be refrigerated? I’m looking for a to die for brownie that I can let sit out all day and have it survive being transported for hours in a car before eating.

  8. An important ingredient missing from this terrific recipe is the tumbler of Bailey’s placed by the right hand of the dessert chef.

  9. Holly, I see in your instructions for these brownies, you say to “refrigerate until set”. Do you store these brownies in the fridge?

    1. You sure can. If your piping frosting you can add it just as you would on a normal cake. If you’re adding sprinkles, you might like to add it once the ganache is spread overtop of the frosting so it ‘sticks’ better. :)

  10. I am making this for a birthday, can it still be decorated with icing ontop? & what is the heavy cream?, does it come in a box or can?
