Super Easy Chocolate Guinness Cake

I have got the easiest chocolate Guinness cake for your St. Patrick’s day baked goods needs. This one is so easy you could make it before you go to work. Yeah, you’ll have to get up a little earlier than usual, but not too much. This cake is just that easy to whip up.

A couple of years ago I made a Guinness cake that was phenomenal! It was a beautiful four layer cake (which was pretty impressive for me since I generally do not make layer cakes…nor do I make them well) that was inhaled as soon as it was put out. Not only was it beautiful, but it was even more delicious. But this year I was looking for something a bit easier.

This Guiness cake is probably the easiest Guinness cake recipe you’ll come across. Yes, it’s just that simple. It’s not gourmet, but it’s definitely delicious (it didn’t last 5 minutes in Craig’s office) and it looks pretty too. It sort of looks like the to of a glass of Guinness.

Hate on me all you want, but this cake starts with a boxed cake mix. Hey, I told you it was really easy. I used Pillsbury Moist Supreme Devil’s Food cake, with pudding in the mix. No, I have not been paid or subsidized to mention this product. I just knew with the few ingredients going into the cake, I needed to use a cake mix with pudding in it. (My first attempts at using mixes without pudding came out kinda dry.)

What naturally goes into a Guinness cake is the next ingredient…Guinness beer and a couple of eggs. That’s it. I told you this was an easy cake. The icing isn’t much more difficult either. It only calls for cream cheese, confectioner’s sugar and cream. So see? You really could make this cake before you head into the office.

As it’s written, this cake is only a single layer, but if you wanted to make it two layers (a bit more impressive looking) all you need to do is double the recipe (and use two cake pans instead of one for the batter).

Celebrate St. Patrick’s Day with this super easy chocolate Guinness cake and get your Guinness on!

Just a cautionary tale….the recipe states you can use one 8″ or 9″ round pan. I currently have this cake in the oven in one 8″ pan. Well I also have a HUGE MESS in the oven too! It OVER FLOWED!!! Save yourselves a mess! Use TWO PANS!!!

Just one cup Guinness? Guess I’ll have to drink the rest of it. Before I go to work. 🙂 This looks terrific — thanks.
