**Disclaimer- This title is in no way meant to be offensive. It is in no relation to the car bombings in Ireland in 1972 and has everything to do with the American beer cocktail, created by Charles Burke Cronin Oat. The Irish Car Bomb features a shot Baileys Irish Cream and Jameson Irish Whiskey being dropped into a pint of Guinness stout, causing a mini explosion.**
It’s about to get real St. Patrick’s Day up in here. My little Irish heart loves this holiday and all the food, festivities and ahem drinking shenanigans involved.
I’m an Irish girl through and through. My maiden name is Gaelic and use to include a “Mc” in the beginning of it but when they got off the boat, the “Mc” was left off.
My first name, Megan, is Welsh but the spelling of Meghan is Irish…go figure!
I have red hair, pale skin and blue eyes. I hated my red hair when I was younger, as I would get teased about it because it was so different from all the other blonde and brunettes in school. Now as a thirty something year old, I love and appreciate my hair color and have zero plans to dye it.
My poor children inherited 2/3 of my Irish traits; pale skin and blue eyes. While I’m proud they’re Irish, I wish they would have gotten their father’s skin complexion. Lifetime stock of sunscreen in this household!
We also named our son, Aiden. (Yes, we spelled it was an “e”) I knew from high school that if I ever had a son, his name would be Aiden and if my husband didn’t like it, it would have been a deal breaker. LOL! I named our son and he named our daughter, fair enough deal.
Aiden is Gaelic, meaning Little Fire and our little boy was born with a touch of red hair that has since disappeared.
Anyways, enough about my Irish family, let’s talk about chocolate brownies, more specifically this Irish Car Bomb Brownie recipe.
These brownies are the bomb, literally! For years, I’ve been making Brown Eyed Baker’s Irish Car Bomb Cupcakes but it was time for my own version of this chocolate boozy triple threat!

Step by step instructions
Guinness Brownie Layer
- Preheat oven to 350 degrees and coat a 9×9 pan with cooking spray and line with parchment paper for easy removal.
- Combine flour, granulated sugar, cocoa powder, brown sugar, salt and baking powder in a large bowl.
- Place 1/2 cup chocolate into a heat proof bowl and microwave until melted. Whisk in butter, vanilla and Guinness. Add eggs, one at a time and whisk until combined.
- Fold in remaining 1/2 cup chocolate chunks.
- Pour batter into prepared pan and bake for 20-22 minutes or until a toothpick inserted comes out clean.
- Place pan on a wire rack to cool completely.
Jameson Ganache Layer
- Once the brownies have cooled start by placing your chocolate into a medium size bowl and microwave until melted.
- Whisk in butter, whiskey and powdered sugar.
- Let set for a minute and then spread evenly over brownies. Allow to set up, about 5 minutes.
Baileys Buttercream Frosting Layer
- In the bowl of your stand mixer fitted with the whisk attachment or into a large bowl, add in your softened butter and whip, scraping down the sides every minute, for 5 minutes.
- Using 1/2 cup at a time, add in your powdered sugar.
- Once all the powdered sugar has been incorporated add in your Baileys and vanilla extract.
- If the frosting is not to your desired consistency and you’d like it thinner, gradually add in a teaspoon of milk until you’ve reach your desired consistency
- Spread frosting on top of the ganache layer and cut into 12 equal squares.
Stout Brownies from a box mix
I understand not everyone has time to make homemade brownies, so I tested this recipe with a boxed brownie mix.
To make stout brownies from a brownie mix, simply replace equal parts of water (called for on the box) with GUINNESS.
When making these Guinness brownies, I recommend using Ghirardelli mix.
If you have the time, I highly recommend making the brownies from scratch.
how to adapt this recipe and variations
- Use room temperature ingredients such as (eggs, butter and beer)
- Use correct measuring tools. When using dry ingredients use measuring cups. When measuring wet ingredients, use a liquid measuring cup. Yes, there is a difference and when it comes to baking, which is a science, it does matter 🙂
- Feel free to use a box mix to make the Guinness Brownies. (see above)
Remember Everyone is Irish on St. Patrick’s Day and you definitely do not need to be Irish to enjoy these Irish Car Bomb Brownies.
For dinner, you could make either:
Sheperd’s Pie Poutine
and these for dessert:
Chocolate Guinness Mini Cakes with Baileys Buttercream
Baileys Mint Chocolate Chip Dip
