I discovered these triple-tier delights while playing around with extra Baileys that was left after hosting a family get-together. The mix of chewy brownie foundation, boozy cream topping and rich chocolate layer is mind-blowing. They seem fancy but use shortcuts that make them quick enough for regular weeknights. When I take these to parties, my container always comes back empty with folks begging to know how I made them.

Brownie Wonder

  • They wow everyone though they secretly start with a box mix
  • The boozy cream gives them a special taste regular treats can't match
  • You'll love that you can fix them up the night before your event
  • Every mouthful offers different sensations in one little square
During our last holiday season, my wife's dad (who "never touches sweets") gobbled up three while just hanging out by the kitchen counter. When everyone was picking up leftovers, he actually called dibs on the remaining pieces! These days, the family expects them at every gathering - my brother's wife once messaged me at midnight wanting to know my technique.

Star Ingredients

  • Store-bought brownie mix cuts your work without hurting the flavor. I've compared them to scratch recipes and honestly? Nobody spotted any difference.
  • Using salted butter for the middle layer balances the sweetness just right. Don't go for the unsalted kind.
  • The Irish Cream shows up in every layer for that signature flavor. Most booze cooks away in the base but stays present in the topping and chocolate glaze.
  • You need real heavy cream to nail the texture in both frosting and glaze. Don't think about swapping in regular milk.
  • Dark chocolate keeps the whole thing from being too sweet. I tried making it with milk chocolate once and it was way too sugary.
I found out about adding Baileys to brownie batter by chance when I ran out of water. That lucky mistake turned basic box brownies into something extraordinary. Now I always keep a mini bottle just for my baking - it's crazy how much it changes things.

Detailed Walkthrough

Getting Ready
Turn your oven on following the box temp. Put parchment in an 8x8 pan with edges hanging out on two sides like handles. Don't skip this paper step or you'll never get these treats out whole!
Batter Magic
Fix the brownie mix per package but swap out water for Baileys. This tiny change makes a huge impact. Pour it all into your lined pan and push the mix out to all corners.
Watch Your Baking
Cook as the box says but look in 3 minutes early. You want them slightly gooey with just a few wet bits on your testing stick. If they go too long, the whole dessert turns dry.
Cool Down Time
Let the base cool all the way before adding anything else. I'm talking totally cool - give it at least 60 minutes. Rush this part and your next layer turns into a melty mess.
Whipping Up Filling
Whip soft butter and vanilla till light. Add sifted sugar bit by bit, then slowly mix in your Baileys. Add heavy cream one spoon at a time until you get a smooth spread.
Smooth It Out
Spread your creamy mix evenly across the cool base. A flat knife works best for this job. Try to make it as smooth as you can since any bumps will show through the top layer.
Chill Break
Put your two-layer treat in the freezer while making the chocolate top. This firms up the cream so hot chocolate won't melt it. This step really matters!
Glossy Top Mix
Warm up cream and Baileys just until tiny bubbles form. Pour this over your chocolate bits and wait 3-4 minutes untouched, then stir slowly until shiny.
Last Layer
Pour this melty chocolate over your cold middle layer and gently push it to all edges. Let it harden fully before cutting - about 60 minutes on the counter or 15 in your fridge.
Smart Cutting
Lift everything out using those paper handles. Cut with a sharp knife, wiping it clean between slices to show off all three pretty layers.

Extra Tips

  • The topping layers still have some alcohol in them - not enough to feel but worth knowing
  • They taste way better when they're not cold from the fridge
  • Let them sit overnight and they'll actually taste even better
My first attempt at these, I skipped freezing the middle layer before adding the chocolate top. The layers mixed together in a swirly pattern. They tasted amazing but missed those clean, separate layers. I've found taking your time makes all the difference with these goodies.

Pretty Presentation

Put squares on a plain white dish to make those layers pop. For casual times, I just throw them on a wooden board. They go perfectly with after-dinner coffee, or with a tiny sip of Baileys for a special touch.

Flavor Twists

Play with different Baileys types like Salted Caramel or Espresso for an easy change. During Christmas, add a tiny bit of mint to the middle and sprinkle crushed candy canes on top before it sets. For chocolate fans, mix small chips into the batter for more texture and chocolate punch.

Staying Fresh

Keep them in a sealed box in your fridge up to 5 days. Take them out 15 minutes before eating for the best taste. They freeze really well too - wrap each piece in plastic, then foil, and freeze up to a month. Let them thaw in the fridge overnight.

Smart Shortcuts

  • Warm your knife under hot water and dry it between cuts for clean edges
  • If your chocolate top looks lumpy, stir in a bit of warm cream
  • The edges get kinda hard in the fridge - cut them off before serving for the softest bites
I've whipped up these boozy brownies for everything from birthdays to Friday night treats. There's just something about that mix of fudgy bottom, creamy middle and crisp chocolate top that people can't resist. My hubby knows when the Baileys bottle appears on the counter, these treats are coming soon - and he better snag one fast before they're all gone. Trust me, every single calorie is worth it!

Recipe FAQs

→ Can I make them alcohol-free?
Sure! Replace Baileys with heavy cream for frosting and ganache. For brownies, follow box instructions with water instead. Add coffee extract to mimic the flavor.
→ Is there much alcohol in these?
Very little. Most of it burns off in baking the brownies. The frosting and ganache use just a small amount—roughly 2 tablespoons each—which ends up being minimal per piece.
→ Can I use homemade brownies?
Of course! Any chewy homemade brownie recipe that fits an 8x8 pan will be great. Bake your favorite, then top it with buttercream and ganache layers.
→ Best way to store these?
Pop them in an airtight container in the fridge for up to 5 days. Let them sit at room temp for 15 minutes before serving. They freeze well for 3 months too!
→ Can I use other Irish cream flavors?
Go for it! Flavors like salted caramel, espresso, or vanilla cinnamon would taste amazing and give the brownies a unique spin.
→ Why freeze before adding ganache?
Freezing makes the buttercream firm so it doesn't melt or mix with the ganache. This keeps the layers neat and pretty.

Skill Level: Moderate

Cuisine Type: American

Output: 16 Serves (16 brownies)

Dietary Options: Vegetarian

Ingredients

→ Brownies

01 1 box of pre-made brownie mix along with the required ingredients (usually oil, eggs, and water) listed on the packaging.

→ Baileys Buttercream

02 ½ cup of softened salted butter
03 1 tsp of vanilla flavoring
04 2½ cups of powdered sugar, sifted to remove clumps
05 2 Tbsp of Baileys Irish Cream
06 3 to 4 Tbsp of heavy cream (adjust based on thickness)

→ Ganache

07 ⅓ cup of heavy cream
08 2 tablespoons of Baileys Irish Cream
09 1 cup of semi-sweet chocolate chips

Steps

Step 01

Fire up your oven to the temperature mentioned on the brownie box. Prepare an 8x8 pan with parchment paper and keep it ready. Mix the brownie box contents with the package-listed ingredients. (For a richer taste, you can swap out the noted ¼ cup water for ¼ cup of Baileys.) Bake as directed and let them cool fully after baking.

Step 02

In a mixing bowl, stir together the softened butter, vanilla, and the powdered sugar. With the mixer on, slowly add 2 tablespoons of Baileys. Gradually mix in the whipping cream—1 tablespoon at a time—until your frosting is light and fluffy.

Step 03

Use a spatula to coat the chilled brownies with the buttercream evenly. Pop the frosted brownies into the freezer while working on the ganache—it’ll make spreading the ganache much easier.

Step 04

In a microwave-safe bowl, combine ⅓ cup of heavy cream and 2 tablespoons Baileys. Heat it up for about 45 to 60 seconds—just until the cream starts bubbling. Pour it over the chocolate chips and let the mix sit for a few minutes. Then, stir it all up until nice and smooth.

Step 05

Pour the finished ganache over the top of the hardened frosting layer. Let it set—either on the counter for an hour or chill it in the fridge for about 15 minutes. Lift the brownies out with the parchment paper edges, slice into uniform squares, and serve right away.

Tips

  1. Since Baileys in the buttercream isn’t heated, a small amount of alcohol remains, but it's minimal.
  2. Expect super rich, silky, and chocolate-packed brownies—perfect with the Baileys touch.
  3. Feel free to add Baileys to one, two, or all three layers. If you want a hint of flavor without too much alcohol, adding it to the buttercream works best.
  4. Don’t forget: the brownies should be completely cool to avoid melting the buttercream.
  5. Freezing the frosted brownies will keep the ganache spreadable and neat when added.
