Happy hump day bakers! I’m always grateful for a long weekend but I’m already wondering how is it not Friday yet? Long three-day weekends have a way of turning into even longer weeks that seem to drag on and on with the promise of Friday dangling in the far off distance. From here on out I’m making a new rule. Chocolate is for Wednesdays. The more the better. We all deserve a hefty dose of chocolate laden brownies to ease us through the week and I’m here to bring them. I don’t typically bake with alcohol, but these triple layer boozy brownies made with Baileys Irish Cream are worth making an exception for. So is this Baileys Dark Chocolate Bundt in case you’re looking for more evidence of this. Easily my favorite bundt cake on the blog. Don’t even get me started on that shiny, chocolatey glaze.

But back to these brownies. In hopes of delivering you a mid-week treat you simply cannot pass up, today we are making a three layer brownie that is as decadent as they come. We’re talking a rich, super fudgy brownie studded with chocolate chips and frosted with a creamy, ultra fluffy Irish cream buttercream. But we don’t stop there because these brownies are the definition of extra. The whole thing is topped with a final coating of deep, dark chocolate ganache. These brownies will knock your socks off and they are definitely for adults only.

These Irish cream fudge brownies are as rich and delicious as they look and you only need a small square to satisfy your sweet tooth. The original recipe is definitely for grown up since you can definitely taste the Irish cream and the alcohol is not baked off. But you’ll be glad to know I have made these brownies into a kid-friendly, mom approved version without the booze and I’m here to tell you that they are just as irresistible. Like kids forming a line at the refrigerator door kind of irresistable. Simply omit the Baileys altogether in the brownies and add an extra tablespoon of heavy cream to the buttercream frosting. Thinking out loud here, you could even substitute the Baileys for an Irish cream flavored coffee creamer.


These brownies may have three decadent layers that look fancy but they are super easy to throw together. These brownies are both easy and delicious and believe me when I say these bad boys are the ultimate chocolate lover’s indulgence. The brownie recipe itself is made from scratch in just one bowl with just a handful of ingredients. They are rich, fudgy, chocolatey perfection! You could certainly use a boxed brownie mix if you are short on time but I find this recipe to be just as quick and homemade brownies are hard to beat. If you do go the store bought route, be sure you use a brownie that isn’t overly ooey gooey. We need a brownie that is sturdy enough to hold the layers on top. To make these brownies we first start by melting the butter and chocolate together. Once smooth and glossy we stir in the sugar, Irish cream, eggs, and vanilla. Give it a thorough mix and then add the dry ingredients and you’re ready to bake. It’s that easy. For best results, keep these two tips in mind… don’t over mix the batter or over bake the brownies. Follow these golden rules and your brownies will be perfectly dense and fudgy – just the way brownies are meant to be. These Irish cream fudgy brownies are hella delicious all on their own but we’re going to take them to full over-the-top status by adding a layer of boozy buttercream and a generous helping of rich, dark chocolate ganache. I mean….talk about at triple threat. These brownies have it A-L-L!!!


This Irish cream buttercream is simple to make and absolutely lick from the spoon worthy. It’s made in a minute with just a few ingredients and it has that extra fluffy texture I love. Be sure to use room temperature butter and sift your confectioner’s sugar for best results. The flavor of the Baileys Irish cream is quite pronounced so a little goes a long way. If you are big on boozy flavor, feel free to add more but taste test the buttercream along the way so you don’t add too much. And don’t even think about frosting the brownies before they have had a chance to cool completely or your buttercream will melt. To set the frosting, place the frosted pan of brownies back in the fridge for one to two hours before adding the final layer of thick chocolate ganache. The waiting is the hardest part but it’s so worth it, pinky swear.


These brownies will fly off the kitchen counter the moment you cut that first square. But if you happen to have a few left over, keep them tightly covered in the refrigerator to preserve that perfect fudgy texture. I LOVE, LOVE brownies cold from the fridge and even moreso straight from the freezer. If you haven’t tried cold brownies, you must! They’re soooo good!!! If you prefer your chocolate at room temp, just let the brownies sit out for 15-20 minutes before digging in.

Happy hump day and happy baking!

A rich and fudgy brownie topped with a fluffy layer of Baileys buttercream and thick dark chocolate ganache. These Irish cream fudge brownies are the ultimate chocolate lover’s dessert for grown ups!



For Brownies

  • 1 stick (1/2 cup) unsalted butter
  • 2/3 cup dark chocolate (I use 70% cocoa, for a sweeter flavor use semi-sweet chocolate)
  • 1/4 cup Bailey’s Irish cream
  • 1/4 cup light brown sugar, packed
  • 1 cup granulated sugar
  • 2 large eggs, room temperature
  • 2 tsp vanilla
  • 1 cup all purpose flour, spooned and leveled
  • 1/4 cup Dutch process unsweetened cocoa
  • 1/2 tsp kosher salt
  • 1/2 cup semi sweet chocolate chips

For Irish Cream Buttercream

  • 3/4 stick unsalted butter, room temperature
  • 1 TBSP brown sugar
  • 1 1/2 cups confectioner’s sugar, sifted
  • 1 TBSP Bailey’s Irish Cream liqueur
  • 1/2 tsp vanilla
  • 1/4 tsp salt
  • 2 TBSP heavy cream

For Ganache

  • 1/2 cup dark chocolate, finely chopped
  • 1/2 cup heavy cream


  1. Preheat oven to 350 degrees.
  2. Spray a 8 x 8 inch baking pan with non-stick baking spray and line with parchment paper. Set aside.
  3. In a medium saucepan over medium low heat, melt together the butter and dark chocolate. Stir often and do not let the mixture get too hot. Remove from heat as soon as the chocolate is melted and smooth.
  4. Add the Bailey’s Irish Cream, granulated sugar, brown sugar, eggs and vanilla. Mix well with a whisk or spatula.
  5. Add the flour, cocoa powder and salt. Mix until just combined. Gently fold in the chocolate chips.
  6. Pour the batter into the prepared pan and use an offset spatula to level the top, gently pushing the batter into the corners of the pan.
  7. Bake for 25-30 minutes or until a toothpick inserted in the center of the pan comes out with moist crumbs attached. Batter should not be raw in the center.
  8. Remove the pan from the oven and allow to cool completely before adding the buttercream.

For Irish Cream Buttercream

  1. Once the brownies are cool, add the butter and brown sugar to the bowl of stand mixer fitted with the paddle attachment. Mix on high speed until fully incorporated and creamy.
  2. Add one half of the confectioner’s sugar and beat on low speed until incorporated. Add the remaining half of the sugar and beat on medium high speed for 2 minutes until light and fluffy.
  3. Add the Bailey’s Irish Cream, vanilla, salt and heavy cream. Beat on medium speed for 30 second and then increase the speed to high and beat for 3-4 minutes until light and fluffy.
  4. Use an offset spatula or table knife to spread the buttercream evenly over the cooled brownies. Place the frosted brownies in the fridge to set for one hour.

For Ganache

  1. Chop the chocolate and place it in a heat safe bowl.
  2. In a small saucepan over medium low, heat the heavy cream until it begins to bubble at the edges. Do not boil. Once simmering, remove from heat and pour the hot cream over the chocolate.
  3. Allow the mixture to sit for 3 minutes and then stir well with a whisk until smooth and glossy.
  4. Pour the ganache over the chilled buttercream and use an offset spatula to spread it evenly across the top, covering the buttercream completely.
  5. Place the brownies back in the refrigerator for 2 hours to chill. To removed the brownies, gently pull up on the parchment paper over hanging the sides of the pan and cut the brownies into 16 even squares using a sharp knife. For best results, rinse the knife under warm water and wipe with a dish towel between each cut.

    These brownies came out very dense and fudgy, and I like those kinds of brownies! My ganache didn’t turn out perfect so I covered the top in chocolate sprinkles. Loved!

    For my family that drinks, I will use the 1/4cup Bailey’s in the brownie part and the 1 TBS, but my friends and I do not drink, so is it okay to skip it? Is there something I should replace it with? Also, can I freeze these? I would like to make them for Christmas ahead of time. Another question is do you have any “directions “/suggestions on mailing these to sisters in Arizona and N. Carolina who live in Vermont? Thank you for the recipe and the help.

      You can substitute the Baileys with whole milk or heavy cream. You can certainly freeze these brownies and defrost at room temperature when ready to serve. Sadly, because of the soft filling layer and top layer of chocolate ganache, I don’t think these bars will hold up well during shipping.

      I’m so glad that you loved this recipe! A warm knife definitely helps…just be sure to clean it well between each slice. For clean, sharp edges, the brownies should be cold.

    I baked these this past weekend and honestly, the best brownies I have ever had. Outstanding recipe…and it really is not difficult in any way. As stated in the description, the scratch brownie layer is no more difficult than a box mix. Thanks for sharing this, these are out of this world!
