These Guinness Irish Cream Cupcakes have a rich, deep flavor. The caramel is great and the Baileys icing is, well… the icing on the cake!

My brother (and sister-in-law, too) moved this week and is no longer a “Hey, want to come over for dinner” distance from us. I am happy for him, truly, but we will all miss him terribly.

His work friends had a going-away party for him at his favorite home-away-from-home, and I brought these cupcakes to send him off. These seemed like cupcakes meant for boys. They are not, of course, just for boys, but they were totally appropriate to eat while drinking Guinness. I am happy to report that they were a hit.

I am not a fan of Guinness, but I love to cook with it. I had the Guinness Cupcakes from Alexandria Cupcake, and they ended up being my favorite flavor, I was shocked! It doesn’t really taste like stout, but it is a rich, deep flavor. The Baileys frosting is perfect on top and the caramel sauce has a little bit of kick from the Jameson. The caramel sauce is a keeper. The perfect consistency, and so pretty. If you need more in-depth instruction on making caramel, I include step-by-step instruction here. The cupcake recipe is from Smitten Kitchen and the caramel is from Gourmet.

Step 1: Add sugar and water in a saucepan. Combine whiskey, cream, and salt in a measuring cup and set aside.

Step 2: Bring sugar to a boil over MED-HIGH heat, without stirring, until the sugar is deep golden brown. It takes about 5 to 10 minutes. Remove the pan from the heat and add the cream. Whisk until it is smooth. Let cool and transfer to a container. I like to use a squeeze bottle, it makes the decorating easier.

Variations

I know that I will get a few emails and comments asking how to make these alcohol-free, and completely respect the choice to not use alcohol. But in this case, I think that there really is no substitute and would probably make something else. Also, these cupcakes are for adults only.

Edit: One reader, Mikki Lee, devised a somewhat-kid-friendly version of the recipe:

I kept the cupcake recipe the same, but cooked the beer and butter mixture longer to burn out the alcohol. Then instead of using baileys – the alcoholic drink – I used baileys Irish cream, the coffee creamer! It worked great. For the caramel, I kept it the same, because as you said, sometimes there really is no substitute! So for half they have the caramel and the other half, green sugar crystals.

FAQs

How many cupcakes does this recipe make?

24. 2 muffin tins.

Could I swing these to gluten-free with the right combo of alternative flours? Or will I just ruin the deliciousness?

I am sure that you can, but I have never played with gf flours. I wish that I could be more helpful.

I do have one problem! They fall right in the center of the cupcake. It is ok because the frosting hides it but I would prefer them not to do this. Any idea what I am doing wrong?

I don’t know why they fall, I just think that it gives more room for frosting!

I want to make them but I don’t have an electric mixer. Should I have any problem?

Just make sure that your butter is really, really soft.

How To Store Guinness Irish Cream Cupcakes

Let the cupcakes cool completely. Storing them while still warm will result in soggy cupcakes from the residual moisture. Place in an airtight container or cake carrier, making sure there is enough room for the icing. Pop in the fridge where they will last for up to 4 days. You can also freeze them for up to 3 months. Just let them thaw at room temperature before serving.
