I had all these plans for making a Baileys Irish Cream flavored dessert this weekend. And then Daylight Savings happened. And taxes happened. And all I really had time to do was drink a lot of Baileys.

I may have actually finished the bottle (there wasn’t that much left when I started!), but luckily, I can make my own homemade Irish Cream liqueur if I need more later this week.

But I did manage to whip up this flourless Baileys chocolate mug cake. I played around with my flourless chocolate mug cake and tweaked it to make a slightly boozy Baileys version. It looked a little plain, so I added a dusting of powdered sugar on top.

This cake has a rich, bittersweet chocolate flavor with just a hint of Irish Cream liqueur.

Ingredients

  • Semisweet chocolate chips
  • Vegetable or canola oil
  • Unsweetened cocoa powder
  • Granulated white sugar
  • Egg
  • Baileys Irish Cream liqueur

Recipe Steps

Melt the chocolate chips with the oil in a large microwave-safe mug. Whisk to combine. Add remaining ingredients. Mix with whisk until smooth.

Microwave the mug cake at full power for about 1 minute. It’s done when the top of the cake should look done with the edges still slightly gooey. Allow the cake to cool for 5-10 minutes.

Tips

When the cake is cooking in the microwave, it will rise very high but will sink back down considerably once finished. This is normal since this is meant to be a rich flourless cake.

You serve it as is or plate the cake in a smaller mug before serving.

I like to add some powdered sugar, but you can also decorate it with whipped cream or a chocolate drizzle. Sometimes we add a small scoop of vanilla ice cream, too.

This mug cake is the perfect sweet treat for St. Patrick’s day. It’s so easy!

  1. I have questions!  1). What size (in ounces) should the mug you bake in be? 2)  If you transfer the dessert to a smaller mug for serving, how do you do so without it falling apart.? Thank you!!

    • I recommend a 16oz mug as the flourless cakes rise quite high during baking. Once it is finished cooking, the cake pulls away from the sides and is about the size of a cupcake so you can use a very large spoon and life it out in one piece to transfer to smaller mug. You could also hold the mug upside down and let it fall out
