Say hello to the best ever chocolate cupcake recipe. For real though, these Guinness Chocolate Cupcakes are insanely delicious. They’re full of that deep chocolate flavor with a hint of Guinness…which only makes the chocolate taste even better. Topped with a salted caramel buttercream, these chocolate cupcakes need to be at the top of your “to bake” list!

What makes Guinness Cupcakes so good?
It’s one of those things that’s hard to explain and you just know when you try it. You might not think Guinness and chocolate go together…especially in cupcakes…but trust me, it’s AH MA ZING.
If you’re thinking, “Can you actually taste the beer?” the answer is no! Or at least not really. There is the slightest HINT of stout flavor but because it goes so well with the chocolate, it just tastes like a really rich and luxurious chocolate cupcake. A fancy chocolate cupcake, if you will.
The best part is that the Guinness makes these super moist chocolate cupcakes. I mean I brought these to work and 5 days later they were STILL good.
The carbonation also helps to lighten the cake so it’s not super dense. It’s the perfect balance of light and fluffy but also rich and moist.

DELICIOUS Salted Caramel Buttercream
You’ve got a super rich chocolate cake so it’s only natural to match it with a luscious salted caramel buttercream, am I right??
I absolutely love this caramel buttercream recipe because of how quick and easy it is to make. It starts with my tried-and-true salted caramel recipe that I’ve used in SO many of my desserts. Seriously, it never fails! And just to name a few:
- Caramel Banana Coffee Cake
- Salted Caramel Cheesecake
- Gluten Free Oatmeal Chocolate Chip Skillet Cookie
After the caramel has had time to cool and thicken, you just add it to this simple American buttercream recipe. Voila! You have salted caramel buttercream. And just as a warning, you’ll be very tempted to eat it by the spoonful.

How to frost cupcakes without a piping bag
If you’re in a pinch or just can’t justify buying piping tips AND piping bags, you can still make your cupcakes look cute! All you need is a butter knife or an offset spatula and you’re good to go.
Start by dolloping about 3 tablespoons worth of frosting into the center of your cupcake. Using the knife or spatula, gently spread it just past the edge of the cupcake.
Turn your knife upright and run it along the edge to create a smooth side.
For this recipe, drizzle on some SLIGHTLY warm salted caramel sauce and use either a spoon or the edge of your knife to make that swooping motion around the top of the cupcake.
Sprinkle on some chopped chocolate, pretzels, sea salt, sprinkles, or nothing at all! They’ll look gorgeous either way.

A couple things to know before baking these Guinness chocolate cupcakes:
- Make sure to use Guinness Extra Stout. This will give you that bold flavor as opposed to the Draught version.
- If you don’t have Dutch Process Cocoa Powder, opt for a dark chocolate cocoa powder to get that deep flavor and color.
- MAKE SURE YOUR CARAMEL IS COOLED TO ROOM TEMPERATURE BEFORE USING. Otherwise your buttercream will melt.
- The batter is very thin so don’t be alarmed. It also might not seem very smooth but it will bake up very nicely.
- These cupcakes bake pretty flat so don’t be alarmed if yours didn’t get much of a rise.
With these tips, you’re on your way to making the best chocolate cupcakes you’ll ever have.

These seriously look SO DAM GOOD!
haha the exact reaction I hoped for!
Can I make these and the frosting one day in advance?
Absolutely! If you’re planning to make the two separate and then frost the day of, keep both in the fridge. Wrap the bowl of frosting in plastic wrap and keep the cupcakes in an air tight container. For the frosting, let it sit out at room temperature for about 20 minutes then whip it up again with an electric mixer and whisk attachment. It’ll be good as new and ready for frosting!
Instead of cupcakes…could I make this in a cake say 20cm spring form? Or small layered cake? Would you have the ratio? 🙂
This recipe should fit in two 6″ cake pans baked at 325 for about 20 minutes. I haven’t tried it myself so I can’t guarantee anything! You could also use my chocolate cake recipe from my Blackberry Chocolate Cake which is just as rich and moist.
Hey there. Delicious cupcake! Love that you can actually taste the Guinness! My issue is that the cupcakes keep sinking after they’re out of the oven. I’m using a convection oven and have adjusted the temp. I have not overmixed. I’m an instruction follower. LOL Any ideas?
It could be that the liners are filled too high! Try filling them halfway and that should do the trick 🙂
I was annoyed because these rose more than I expected and overflowed the tins. They felt heavy and dense coming out. Then I thought the homemade caramel was too salty, and I considered not using it. I’m so glad I persisted in finishing them because they are AMAZING. They are moist and fluffy when cooled, and the frosting is perfect.
