A tip of the bottle seems to make most recipes better, and these Irish cream brownies are no exception!

Not only are these fudgy bars a delectable after dinner treat, but they make tasty homemade gifts to give your friends for the holidays.

I also have a salted caramel brownie recipe with a hint of smokiness from Jack Daniel’s whiskey. Or, try out my zesty Margarita cupcakes. No kids allowed at this dessert table!

You can even flip the script and make some cocktails that taste like your favorite sweet treats! Mix up a round of sugar cookie martinis or these creamy strawberry cheesecake pudding shots.

Boozy Brownies – Tips and Tricks

  • Make ‘em boozier – You can always add a little bit more Baileys to the brownies to really bring out that flavor!
  • Use the toothpick method. A great way to test if your Irish cream brownies are finished is by sticking a toothpick in the middle of them. If it comes out clean, they’re ready to be cooled.
  • Serve them warm or cold. While I love a fresh brownie straight out of the oven, these will be just as tasty if you enjoy them at room temperature.
  • Add a garnish: You can complete these treats by adding a swirl of whipped cream or even a maraschino cherry on top if you’re feeling it.
  • Need a larger batch? This recipe can easily be doubled or tripled depending on the number of guests. Just be sure to divide the batter between multiple baking pans!

FAQ – Common Recipe Questions

How do I store Irish cream brownies?

Once cooled, transfer them to an airtight container or Ziplock bag and keep them at room temperature for up to a week.

You can also freeze them for up to 3 months for a make-ahead treat. Let them thaw on the counter until softened, or warm up individual squares in the microwave in 15-second intervals.

Do I have to add espresso powder?

Not necessarily – this is just a well-known trick to really bring out that intense chocolate flavor. I promise it won’t make your Baileys brownies taste like coffee.

You can certainly leave it out to save a trip to the store or if you prefer not to have the added caffeine.

Can I use a homemade brownie mix?

Absolutely! Any brownie mix – store bought or homemade – will turn out delicious.

I love using Ghiradelli’s Double Chocolate Premium Brownie Mix because the chocolate flavor pairs extremely well with the espresso and Baileys.

For topping

  • Enjoy!

Donna’s Notes

You can store the brownies in an airtight container or Ziplock bag at room temperature. When stored this way, the brownies can easily last a week.
We love these fresh out of the oven or warmed up and served with ice cream, but they are just as delicious when cooled down to room temperature.
You can use your family’s favorite brand of brownie mix. I love using Ghirardelli’s Double Chocolate Premium Brownie Mix because the chocolate is soooo good and pairs very well with the espresso and Bailey’s.

    Yummy. Loved the idea of adding Irish cream into the mix, so I had to try it. The flavor is amazing and so rich. Was a great treat for me and my husband.
