These Baileys Brownies have a deep chocolate fudge flavor with the perfect amount of Baileys Irish Cream in the brownie and the decadent frosting. This is the perfect treat to settle in with someone you love and enjoy watching the new film, Wild Mountain Thyme.

I’m so happy to be working with Bleecker Street to bring you this delicious dessert.

There have been so many things I have missed this year. High up on that list is seeing movies in the theater and travel. Never someone who was full of wanderlust, I’m so surprised at how much I miss it. But I truly do.

Which is why I could not be more excited for the premier of Wild Mountain Thyme now in theaters and available on demand. A romantic comedy with an all star cast (Emily Blunt, Jamie Dornan, Jon Hamm, and Christopher Walken to name a few) set in beautiful Ireland. This movie is the perfect escape for the holiday season. It is full of beautiful images of Ireland and layered with a story that will suck you in from the beginning. Exactly what my 2020 heart needs.

How to Make Baileys Brownies

In order to make this the movie night of our dreams, I’m making us some Baileys Brownies – deep chocolate brownies with Irish cream liqueur.

Here is a brief overview of what you’ll need to do before movie night. Get the full measurements and instructions below.

  1. Combine the dry ingredients: In a large bowl whisk together flour, cocoa powder, and salt.
  2. Melt chocolate and butter: Combine chocolate chips and butter in a microwave safe bowl and heat at short intervals until melted. Mix in sugar.
  3. Combine all the ingredients: Combine the wet ingredients into the dry ingredients. Add in the remaining ingredients including the Baileys. And bake.
  4. Make the frosting: Melt butter, sugar, and Baileys together and boil. Stir in chocolate chip chips and pour frosting over cooled brownies.

Baileys Brownies Tips & Tricks

Here are a few things that will help this recipe turn out perfect.

  • Scoop and level your flour. Use a dry measuring cup (the plastic kind) and use a spoon to scoop the flour out of the container into the measuring cup, then level it off.
  • Microwave on intervals. When melting the chocolate and butter, you really do need to do 30 second intervals so it melts into the smooth mixture you are looking for.
  • The batter is thick. Do not stress when your batter is really thick. That’s how this one is. It will be delicious I promise.
  • Pour frosting immediately. For best results you need to pour the frosting all over the brownies right away and tilt the pan to spread it out.

Making Movie Night Special at Home

If there is anything we have learned this year, it’s that we are creative and can come up with new ways to make things special. Here are some ideas to make watching Wild Mountain Thyme a special date night.

Make sure the kids are occupied. Whether that is a movie night for them in a separate room, free rein on video games, or waiting until after bedtime, make sure they are busy.

Get cozy. Pull out all the stops with the coziest blankets, pillows, and jammies.

Make Baileys Brownies. This went without saying, right?

These Baileys Brownies are fudgey, chocolatey, and with the perfect amount of Baileys Irish Cream in the brownie and the decadant frosting.


For Brownies

  • 2 cups all purposed flour read how to measure flour here
  • 2 cups granulated sugar
  • 1/2 teaspoon salt
  • 1/2 cup cocoa powder
  • 16 tablespoons unsalted butter
  • 1/2 cup chocolate chips (I used semi sweet)
  • 2 teaspoons vanilla
  • 3 eggs
  • 1/3 cup Baileys Irish Cream

For Frosting

  • 1 1/2 cups granulated sugar
  • 8 tablespoons butter
  • 1/3 cup Baileys Irish Cream
  • 1/2 cup chocolate chips (I used semi sweet)


  • Preheat your oven to 350 degrees. Spray a 9 by 13 inch baking dish with cooking spray. Set aside.
  • In a large bowl, mix together the flour, cocoa powder, and salt. Set aside.
  • In a medium microwave safe bowl combine the butter and chocolate chips. Microwave at 30 second intervals, stirring in between, until the butter and chocolate are fully melted and smooth.
  • Whisk the sugar into the butter and chocolate mixture. The mixture will be a little grainy, but should be consistent throughout.
  • Pour the chocolate mixture into the flour mixture. Stir to combine. The batter will be very thick. Stir in the eggs, vanilla, and finally the baileys..
  • Spread the batter into the prepared pan. Bake for 30.

For the Frosting

  • Once the brownies have cooled, make the frosting. Combine the sugar, butter, and baileys in a heavy bottomed saucepan, stirring until the butter is fully melted and the sugar is incorporated.
  • Bring to a boil and let boil for 1 minute. Remove from the heat and stir in the chocolate chips. Continue stirring until it is smooth. Pour immediately over the brownies.
  • Cut the brownies and enjoy. Store in an airtight container for up to 1 week.

    OMG!!! My heart is beyond happy. My two food loves are brownies and Bailey’s. What’s not to love!!

      I hope you love these, Zara!

  2. Vicky says

    What type of sugars do you use in the baileys brownies please?

    • Lisa Longley says

      It’s granulated sugar.

  3. clarissa says

    thank.i will try it.

  4. Renate says

    I’m wondering could I make these gluten free somehow??

    • Lisa Longley says

      Hi Renate! From what I have read, gluten flour can’t be exchanged 1 for 1 with all purpose flour in baking recipes. Other things need to be tweaked as well. So I would need to play with it, and unfortunately I just don’t have a lot of gluten free baking experience.

  5. Lori says

    Hi !! I made the Baileys brownies for my cookie trays. When I used granulated sugar in the frosting, it came out gritty. Does that need to be powered sugar instead ? Your brownie part of the recipe is so delicious !! Thank you for sharing all your wonderful recipes !!

    • Lisa Longley says

      I haven’t made it with powdered sugar, but my experience with this is that the once it was on the brownies and set, you couldn’t taste the grittiness. Is it possible I need to add a note about whisking longer?

  6. Rhona says

    Can you use as good quality chocolate instead of chocolate chips? I live in the UK

    Love this recipe! Could I use something else, like whole milk or cream instead of the baileys to make a different flavour frosting? Would they still be ok to store at room temperature for up to a week?

    • Lisa Longley says

      I would want to play with it a little bit. We are using the Baileys in the brownies and the frosting, so while I think it would work fine, I’d want to test it.
