Bailey’s Irish Cream Mug Cake

I like desserts made with a little bit of alcohol, so it was only a matter of time before I graduated to making mug cakes with alcohol. First up, Bailey’s Irish Cream mug cake.

Bailey’s is sweet on its own, so it was easy to add it as a variation to previous mug cakes I made without having to fiddle with the recipe too much.

You can definitely taste the Bailey’s in this cake. It’s almost a little too strong. Like all the other mug cakes I’ve made, this is super easy to put together and cook in the microwave.

I’ll have to make this again for St. Patrick’s Day.

Here’s the rest of my mug cake series:

Bailey's Mug Cake


5 1/2 tablespoons all-purpose flour
4 tablespoons sugar
1/8 teaspoon baking powder
1 egg
3 tablespoons Bailey's Irish Cream
3 tablespoons oil


1. Combine all ingredients into oversized mug. Stir with a small whisk or fork until batter is smooth.
2. Microwave for 1 1/2 minutes. If cake is not done, microwave for an additional 30 seconds. Serve while warm.

  1. YUMMY! Love Bailey’s! Have you ever heard of the cookbook called Booze Cakes? It’s on my wishlist because it has tons of alcohol-y dessert recipes!

  2. Another of your mug cakes!!!
    I love them so much!! Then, I never make one, cos I turn on the oven, but seriously, I can’t stop thinking about making them.
    Yeah, it’s difficult to understand me.
    And Bailey’s, I love so much this, that I can’t think in only a mug!!

  3. I too love Mug cakes (I bet you could cut the sugar down on this a little bit since they Bailey’s is so sweet?) I might have to add that Booze Cakes Book Ann mentioned to my list too!!

    Loving your whole collection of Mugs AND of course your cakes 🙂

    • Actually I think the sugar was about right. The strong taste of alcohol kind of needs more sugar to counterbalance I think. But you could try cutting some out too to save calories. I hope you try some recipes out!

  4. The Spirited Baker by Marie Porter is also AWESOME for “boozy” recipes. Check out Celebration Generation (the name of her company) on Facebook, or Google it. She’s AMAZING. I can’t wait to make this Bailey’s mug cake tomorrow; I’m taking the ingredients for all of us to make our own while with a group on a winter lake-cabin weekend.

  5. Hi! I have a little question.. Is it possible to cook it in an oven instead? If it’s possible, how long does it should take and how high the temp should be?
    Thank you!

    • Hi Rubis, Unfortunately I’ve never tried making it in the oven. My biggest concern is that you would need to find a mug that could bake in the oven without breaking. If I were to experiment, I would set the baking temperature at 350F, and I would estimate that it would take about 10-15 to cook. But I’ve never actually tried it.

  6. Hmmm. Had high hopes for this recipe! I followed the recipe exactly but it turned out bland in my opinion. Perfect cake texture, I had to microwave for 3 minutes total but it got there. Just kind of boring. Melted some chocolate chips on top to add flavor and sweetness.

    • Sorry to her you thought it was bland. Its not my favorite of the mug cakes bit it does taste like baileys and cake which was really was all that I was trying to achieve. Mug cakes sort of limit what you can do to the cake

  7. Well, this recipe sparked for me! I just love mug cakes and always on the hunt for an unusual one. Only problem was I had no Baileys, so what to do coz I just had to try this cake! Aha!… I substituted with ponche de creme and coquito leftover from Christmas. I live in the Caribbean and these are similar to eggnog except we use our West Indian rum instead of brandy and coquito is the Puerto Rican version which has coconut milk and cream added. The cake was absolutely delicious and good texture; 2 mins in microwave just right. Thanks!

    • I’m so happy to hear about your version and that it turned out well for you! It always makes me happy to hear people with positive responses.

  8. Is a Kahlua mug cake in your future?

  9. Hi, I was wondering if you’ve ever tried making a lemon mug cake?

  10. Hello, I’m french, and it’s very difficult to find recipe of Mug Cakes on french websites. So I’ve search on english/american websites and I find yours ! That’s so amazing because you have a lot of recipe of Mug Cakes and I love them 😉

    I’m sorry if my english is bad, I try to talk without translator !

    Thank you for all this recipes !

  11. Hi! Love your site and all the varieties of mug cakes!! Question for you, I do not have Baileys Irish Creme, but do have the Irish Creme flavored coffee creamer. Do you think I can use this instead?

    • I haven’t tried, so I’m not positive. My only worry is that the Bailey’s basically evaporates for the most part when it’s cooked, whereas the creamer would remain an extra liquid to the batter, so I’m not sure if it would be too much liquid and may need some adjusting.

  12. This is my favorite meal replacement (can’t quite call it a snack)! I use biscotti flavored Bailey’s and it’s delicious. I also use self-rising flour (because I hope for fluffy cake and want to get rid of the SRF).


  13. Yummy!!! Just tried it! Wonderful flavor, I’m having it with Caramel tea 🙂

    Wonder if it can also be baked in a regular oven.

    • I’ve never tried baking them in the oven, though I know people always ask me that. But when I make them, I always forget to test it out!

  14. Unfortunately this was an utter fail. The cake was very gummy and half cooked. When I put it on for longer the texture was very strange. The cake was also a little bland… so we smothered it in icecream… not much of an improvement.

    • I’m not sure where yours went wrong. You definitely don’t want it half cooked. You might want to try using a different mug because sometimes a certain mug might heat unevenly. And you want to make sure your ingredients are thoroughly mixed before heating it up. As you can see from the comments, other people made it successfully.

  15. if u cook it too long, it bounces right out of the cup. rubbery consistency.

  16. Oh, YUM! This came out perfect at 2 minutes, with enough of the Bailey’s flavour coming through to make it tasty. It did scare me a little when I saw it standing almost two inches above the rim of my 12-ounce cappuccino mug while cooking, but it settled down once the microwave shut off, and it was solid enough by then it didn’t spill over the edge. Definitely a keeper!

    • glad this worked out. I usually actually recommend a 16 oz mug. 12 oz usually works but it’s like the bare minimum and might spill over.

  17. How many calories is this?
