Irish Cream Chocolate Brownie Recipe - This easy brownie recipe is full of Irish Cream and Chocolate flavor! Makes a cake like brownie that is perfect for dessert!

So let’s be real here.  I have never met a homemade brownie that I didn’t like.  Cakey, fudgy, frosted, glazed, plain, stuffed or gooey.  You name it.  I just LOVE brownies!

Sure you can go the boxed brownie route.  I’m not going to judge.  They certainly have their time and place.

But, if you have to get out the eggs and oil anyway.  Why not just make the entire batch from scratch?

Not only will you get homemade brownie bragging rights.  You can also tweak the flavors however you want.  Like I did with this Irish Cream Chocolate Brownie Recipe.

So put that box back in your pantry.  Save it for a chocolate emergency.  And make these brownies instead!

  1. Swooning at the double dose of Irish cream! Marvelous brownies!!!

  2. That frosting looks so creamy and decadent.

  3. These look absolutely sinfully wonderful!!!!

    • Nicole Harris says:

      Thanks! These brownies are sinful and heavenly all at the same time ๐Ÿ˜€

  4. dian says:

    These sound AMAZING!! What could I substitute for the Whiskey???

    • Stacey says:

      I am sure you could substitute coffee for the whiskey or even chocolate syrup.

      • Nicole Harris says:

        Great suggestions! And now I’m craving coffee brownies ๐Ÿ™‚

  5. Jennifer says:

    I just made these for my co-workers for tomorrow and it’s driving me crazy that I can’t cut into them to sample. The batter was delicious, as was the frosting. I can only assume the end product is delicious as well! Only thing I’m worried about is that my temperamental (no pun intended) oven yielded firm results at only 28 minutes…hope I didn’t dry them out! Then again, who would complain, right?


  6. Never have I seen brownies look so good before.. the height of these is just incredible!

  7. With Irish cream whisky, do you mean like Bailey’s, or something stronger?

  8. I’m using a 9ร—13 baking dish, should I double ke this recipe?

    • Nicole Harris says:

      I always make my brownies in a small batch. But yes, for the larger pan go ahead and double. The cooking time may need to be adjusted as well. So keep a close eye on it.

  9. Whoa, yum yum!! I have featured this amazing recipe in the Absolute Best Brownie Recipe Roundup over at! Keep those yummy ideas coming ๐Ÿ™‚ xo

  10. Janice says:

    I’m a St. Patty’s baby. And I love all things St. Patrick. But I don’t use alcohol.What could I use to substitute for whiskey?

  11. Sounds so good! Love that you put baileys in the brownie mix!

  12. Carmen says:

    I made these this week and LOVED them. The frosting is my new go-to recipe. Thank you so much for posting this!

  13. Sarah says:

    For those not wanting to use alcohol, you can try substituting Irish Cream flavoured coffee creamer instead!

  14. Elizabeth says:

    My frosting looks nothing like yours. I don’t know what happened. Hopefully it still taste good.

    • Nicole Harris says:

      Oh no! I hope it tastes great too. Is yours thicker or thinner than my frosting?

      • Elizabeth says:

        It still tasted fine. But it was thinner and a lot darker. Your looks fluffy my is more like a glaze. Maybe my butter was to soft. I did as the directions said so I don’t know

        • Nicole Harris says:

          If it turned out more like a glaze I would guess that the butter may have gotten too warm. I’m glad it still tasted good though … that is the most important thing!

  15. I made these this afternoon and they are absolutely heavenly!!! I baked them 28 minutes but then that’s probably just my oven. The frosting wasn’t as light of a color like in your picture but that’s ok. Seriously, they are super good!!!! Thanks for a great recipe!

    • Nicole Harris says:

      Awesome! I’m glad you enjoyed. Now I’m craving brownies ๐Ÿ˜€

  16. These are delicious! Checked mine at 27 minutes and they were completely done. I was afraid they’d be dry and overbaked, but they are not! The frosting is to-die-for! Thank you for a great recipe ๐Ÿ™‚
