Ingredients for Irish Cream Frosted Brownies
Alright, let’s gather our goodies! Don’t worry, it looks like a lot, but it’s mostly pantry staples. I always like to get everything prepped before I start, makes the whole process way smoother. Here’s what you’ll need for these amazing Irish Cream Frosted Brownies:
Brownie Ingredients
Okay, for the actual brownies, you’ll need:
- 1 cup (that’s 2 sticks or 227g) of unsalted butter. Make sure it’s real butter, not margarine. Trust me on this one!
- 2 1/2 cups (500g) of granulated sugar. Plain ol’ white sugar works perfectly!
- 2 tablespoons (30mL) of canola oil. This helps keep ’em extra moist.
- A splash of vanilla – 1 tablespoon!
- 5 large eggs. Gotta be large!
- 1 cup (130g) of all-purpose flour. The regular kind is great.
- 1/2 cup + 1 tablespoon (57g) Dutch-processed cocoa powder. This gives it that deep chocolate flavor.
- 1/4 cup (25g) black cocoa powder (or more Dutch-processed). This is optional, but it makes them super dark and fudgy!
- 2 tablespoons (20g) malted milk powder (optional). This adds a little something special, but don’t sweat it if you don’t have any.
- 3/4 teaspoon of salt. Just a pinch to balance the sweetness!
- And finally, 4 ounces of chopped baking chocolate (or 1/2 cup mini semi-sweet chocolate chips). I like chunks in my brownies!
Frosting Ingredients
For that dreamy Irish Cream frosting, you’ll need:
- 1 cup (2 sticks or 227g) of salted butter, softened. This is important! Salted butter adds a little zing.
- 4 cups (520g) of powdered sugar. Also called confectioners’ sugar. Don’t use granulated!
- 2 ounces (60mL) of Irish Cream liqueur. Baileys is my go-to, but use whatever you like!
- 1 tablespoon of vanilla extract. Because vanilla makes everything better.
Ganache Ingredients
And lastly, for that decadent ganache:
- 4 ounces (113g) of bittersweet chocolate. Chop it up nice and small!
- 3 ounces (90mL) of heavy cream. Don’t skimp on the fat content here!
- 2 ounces (60mL) of Irish Cream liqueur. More Baileys for me!
- 1 tablespoon (14g) of salted butter. Adds a little shine and smoothness.
How to Make Irish Cream Frosted Brownies: Step-by-Step Instructions
Okay, here’s where the magic happens! Don’t be intimidated, I promise it’s easier than it looks. Just follow along, and you’ll have the most amazing Irish Cream Frosted Brownies ever!
Making the Brownies
First things first: Preheat your oven to 350 degrees F. And grab your pan – either an 8×8, 9×9 or 9×13 inch metal pan will work. I like to line it with parchment paper so the brownies pop right out. Just spray it lightly with cooking spray, too, for extra insurance. Make sure the parchment hangs over the edges – makes life so much easier later!
Now, melt that 1 cup of unsalted butter in a saucepan over low heat. Add the 2 1/2 cups of granulated sugar and stir until it’s all smooth and kinda emulsified. You don’t want any separated butter hanging out. Take it off the heat and let it cool for like, 5 minutes, stirring now and then to help it cool down.
Stir in the 2 tablespoons of canola oil and 1 tablespoon of vanilla extract. Make sure it’s all combined, no oily puddles allowed! Then, beat in those 5 large eggs, one at a time. Mix until just combined after each one. Don’t overmix!
Sift together the 1 cup of flour, cocoa powders (both kinds!), malted milk powder (if you’re using it), and 3/4 teaspoon of salt. Gently stir this into the wet ingredients until almost all the dry streaks are gone. Then, fold in the chopped chocolate or chocolate chips.
Pour the batter into your prepared pan and bake! If you’re using a 9×13 inch pan, bake for 25 to 30 minutes. A smaller 9×9 inch pan will need 40 to 45 minutes. Let them cool completely before frosting – this is important!
Preparing the Irish Cream Frosting
While the brownies are cooling, let’s make that frosting! Beat 1 cup of softened salted butter in a mixer until it’s nice and fluffy. Gradually add the 4 cups of powdered sugar, mixing on low speed (or “stir”) so you don’t end up with a sugar cloud. Then mix in the 2 ounces of Irish Cream liqueur and 1 tablespoon of vanilla extract. Increase the speed to medium-high and whip for 3-4 minutes, until it’s light and fluffy. Scrape the bowl every now and then to make sure everything gets mixed in!
Making the Ganache
Chop up the 4 ounces of bittersweet chocolate and put it in a bowl with the 3 ounces of heavy cream and 2 ounces of Irish Cream liqueur. Microwave for 1 minute, then let it sit in the microwave for 5 minutes (don’t open it!). This helps the chocolate melt gently. After 5 minutes, whisk it all together until smooth. If there are still some lumps, microwave for another 15 seconds. Finally, whisk in 1 tablespoon of salted butter. This makes it so shiny!
Assembling the Irish Cream Frosted Brownies
Spread the frosting evenly over the cooled brownies. Then, pour the ganache over the frosting and spread it to the edges. Now, the hardest part: let it set for at least 30 minutes before slicing. If you want to add sprinkles, do it now, before the ganache sets! Slice with a sharp knife (a plastic one works great too!). I like to chill mine for a few minutes before slicing, it helps get cleaner cuts. But I always let them come back to room temperature before serving – they just taste better that way!
Tips for the Best Irish Cream Frosted Brownies
Want to take these Irish Cream Frosted Brownies from “good” to “OMG!”? Here are a few little secrets I’ve learned along the way…
Achieving the Perfect Brownie Texture
Nobody wants dry brownies! The key is to not overbake them. Start checking them a few minutes before the recommended time. You want a toothpick to come out with moist crumbs clinging to it, not totally clean. Trust me, slightly underbaked is way better than overbaked!
Getting the Ganache Just Right
Ganache too thick? Add a tiny bit more Irish Cream liqueur, a teaspoon at a time, until it reaches the perfect pouring consistency. Too thin? Pop it in the fridge for a few minutes to firm up! It’s all about finding that sweet spot.
Slicing the Brownies Neatly
Patience is key! Let the ganache set completely before slicing. If you’re in a hurry, chill the brownies for about 30 minutes before slicing. And use a warm, clean knife for each cut. Wipe it off between slices for extra-clean edges. Looks so much nicer, right?
Irish Cream Frosted Brownies Variations
Okay, so you’ve mastered the basic recipe? Awesome! Now let’s get a little crazy! Here are some fun ways to mix things up with these Irish Cream Frosted Brownies:
Different Irish Cream Flavors
Did you know Baileys comes in, like, a million flavors? Try the Salted Caramel or Espresso Creme in the frosting and ganache! It’s a subtle change, but totally worth it!
Adding Spices
Want a little warmth? A pinch of cinnamon or nutmeg in the brownie batter is amazing, especially around the holidays! Just don’t go overboard, a little goes a long way.
Topping Variations
Sprinkles are fun, but what about toasted nuts? Or shaved chocolate? Or even a drizzle of caramel sauce on top of the ganache? The possibilities are endless! Get creative and make these Irish Cream Frosted Brownies your own!
Serving Suggestions for Your Irish Cream Frosted Brownies
Okay, you’ve got these amazing Irish Cream Frosted Brownies…now what? Here are a few ideas to make them even more irresistible!
Perfect Pairings
Honestly, these are pretty perfect on their own, but a scoop of vanilla ice cream on the side? Yes, please! Or maybe a scoop of coffee ice cream to really amp up the richness. And a cup of hot coffee or tea? Total perfection!
Presentation Ideas
Want to get fancy? Dust a plate with powdered sugar and arrange a few brownie squares on top. Drizzle a little extra ganache for a real wow factor! Or just pile ’em high on a platter and let everyone dig in – that works too!
Storing and Reheating Your Irish Cream Frosted Brownies
So, you’ve somehow managed to not eat all these Irish Cream Frosted Brownies in one sitting? Impressive! Here’s how to keep ’em fresh:
Storage Instructions
The best way? Pop ’em in an airtight container and keep them in the fridge. They’ll stay good for about a week (if they last that long!). You can also freeze them for up to 2 months. Just wrap them individually in plastic wrap first.
Reheating Tips
If you’ve frozen them, let them thaw in the fridge overnight. To reheat, microwave for just a few seconds – seriously, like 5-10 seconds – or let them come to room temperature. You don’t want to melt that gorgeous ganache!
Frequently Asked Questions About Irish Cream Frosted Brownies
Got questions? I’ve got answers! Here are some of the most common things people ask me about these amazing Irish Cream Frosted Brownies:
Can I make these Irish Cream Frosted Brownies ahead of time?
Absolutely! In fact, I often do. The brownies themselves can be made a day or two in advance, just wrap them tightly. The frosting and ganache are best made closer to serving, but you can make them ahead and store them separately in the fridge. Just let everything come to room temperature before assembling. Trust me, it’s a lifesaver when you’re short on time!
Can I use a different type of chocolate?
Sure thing! If you’re not a fan of bittersweet, you can use semi-sweet chocolate in the ganache. Just keep in mind it will make the ganache sweeter. Milk chocolate? Probably not the best choice, it might be too sweet. Experiment and see what you like! That’s the fun of baking, right?
Can I make Irish Cream Frosted Brownies without alcohol?
Yep! If you want to skip the Irish Cream liqueur (or need to!), you can substitute it with Irish cream flavored coffee creamer or even just milk with a teaspoon of vanilla and a drop or two of rum extract. It won’t be exactly the same, but it’ll still be delicious! I’ve done it, and nobody even noticed!
How do I prevent my brownies from being dry?
Dry brownies are the WORST! The biggest culprit is overbaking. Make sure you’re checking them a few minutes early. And remember, ovens vary! If your oven runs hot, you might need to reduce the baking time a bit. Also, make sure you’re measuring your flour accurately – too much flour = dry brownies. I like to spoon it into the measuring cup, then level it off. Happy baking!

Decadent Irish Cream Frosted Brownies. Enjoy rich brownies with Irish Cream frosting and ganache.
Ingredients
- Brownies:
- 1 cup unsalted butter (227g)
- 2 1/2 cups granulated sugar (500g)
- 2 tablespoons canola oil (30mL)
- 1 tablespoon vanilla extract
- 5 large eggs
- 1 cup all purpose flour (130g)
- 1/2 cup + 1 tablespoon Dutch processed cocoa powder (57g)
- 1/4 cup black cocoa powder (25g), or additional Dutch processed
- 2 tablespoons malted milk powder (20g), optional
- 3/4 teaspoon salt
- 4 ounces chopped baking chocolate or 1/2 cup mini semi sweet chocolate chips
- Frosting:
- 1 cup salted butter (227g), softened
- 4 cups powdered sugar (520g)
- 2 ounces Irish Cream liqueur (60mL)
- 1 tablespoon vanilla extract
- Ganache:
- 4 ounces bittersweet chocolate (113g)
- 3 ounces heavy cream (90mL)
- 2 ounces Irish Cream liqueur (60mL)
- 1 tablespoon salted butter (14g)
Instructions
- Brownies: Preheat oven to 350 degrees F and line a metal 8×8, 9×9, or 9×13 inch metal cake pan with parchment paper and spray lightly with cooking spray. Make sure some of the parchment is over the edge of the pan for easy removal. This may require two sheets, one going in each direction for a 9×13 inch pan. Make sure the one that goes across the shorter distance is under the one that goes along the full length of the pan.
- Melt 1 cup unsalted butter in a heavy bottomed saucepan over low heat. Add 2 1/2 cups granulated sugar and stir until smooth, the butter and sugar have started emulsifying, and no butter is separated from the sugar. Remove from heat and let the mixture cool for 5 minutes, stirring often to release heat.
- Add 2 tablespoons canola oil and 1 tablespoon vanilla extract to the butter and sugar and beat them in with a rubber spatula until fully combined and there is no separation between the ingredients, no oil resting on top.
- Beat in 5 large eggs one at a time, beating with the spatula or a fork after each one. Mix until fully incorporated.
- Sift the 1 cup all purpose flour, 1/2 cup + 1 tablespoon Dutch processed cocoa powder, 1/4 cup black cocoa powder, 2 tablespoons malted milk powder, and 3/4 teaspoon salt into the butter and sugar mixture, stirring gently with a rubber spatula just until almost all the dry streaks are gone.
- Fold in the 4 ounces chopped baking chocolate or mini chocolate chips.
- Pour the brownie batter into the prepared baking pan and bake for 25 to 30 minutes for a 9×13 inch pan or 40 to 45 minutes for a 9×9 inch pan.
- Cool before removing from the pan and frosting.
- Frosting: While the brownies are cooling, beat 1 cup salted butter in a stand mixer fitted with a paddle attachment.
- Add the 4 cups powdered sugar, 2 ounces Irish Cream liqueur, and 1 tablespoon vanilla extract a little at a time, mixing on stir speed between additions just until combined.
- Increase speed to medium high and whip until smooth and fluffy for about 3 to 4 minutes, stopping to scrape the paddle and bowl about every minute. The frosting should be a pale beige, it will darken as it rests.
- Spread the frosting over the cooled brownies with an offset spatula so that it is as level as possible.
- Ganache: Chop the 4 ounces bittersweet chocolate and add it to a medium bowl with 3 ounces heavy cream and 2 ounces Irish Cream liqueur and microwave for 1 minute. Let set in the microwave for 5 minutes.
- Remove from the microwave and whisk until smooth. If there are still some small lumps of chocolate, microwave for an additional 15 seconds.
- Once smooth, whisk in 1 tablespoon salted butter.
- Pour the ganache over the top of the frosting, spread it out to the edges, and let it set up for at least 30 minutes before slicing. If using sprinkles to make them more festive, add them now before the ganache sets up.
- Slice with a sharp or large plastic knife. You can chill the brownies once frosted for cleaner cuts, but I recommend letting them get to room temperature before serving. You can also slice the brownies first and then pipe the frosting and drizzle the ganache on top.
Notes
- For cleaner cuts, chill the brownies after frosting.
- Let brownies reach room temperature before serving.
- Slice brownies first, then pipe frosting and drizzle ganache as an alternative.
