These decadent Guinness Chocolate Cupcakes are rich, most, and super chocolatey! They’re made with basic ingredients and topped with a rich chocolate cream cheese frosting. The addition of Guinness enhances the chocolate flavor, and makes these a fun St. Patrick’s Day treat!
Now, if you’re already skeptical of these cupcakes, let me just tell you – Guinness is SO good in desserts! It enhances the chocolate flavor without giving a super strong beer taste, so even people who don’t like beer (me!) will love these. Let’s make ’em!
How to Make Guinness Chocolate Cupcakes:
Start by mixing up a super simple chocolate batter. You’ll need the usual cast of basic ingredients:
- Brown & granulated sugar
- Cocoa powder
- Baking soda & powder
- Espresso powder
- Greek Yogurt
- Vegetable Oil
- Vanilla extract
Surprisingly, cupcakes made with vegetable oil rather than butter are incredibly moist and tender! And, this batter comes together so easily – just whisk together the dry ingredients, and then stir in the wet. It’s that simple!
Filling the cupcake liners:
Add cupcake liners to your pan, and fill about 2/3 of the way full. If you fill them more than this, the cupcakes will balloon out over the top of each well during the bake. In general, it’s a good rule of thumb to only fill your cupcake liners 2/3 of the way.
Bake your cupcakes:
Bake the cupcakes for 14 to 16 minutes. They’ll be super moist – a toothpick will pull out some moist crumbs, but shouldn’t pull out any wet batter. Set them aside to cool for a bit, then remove them from the pan and let them cool completely before frosting them. Frosting will melt right off of a warm or hot cupcake.
Just look at the deep chocolatey goodness of those cupcakes!
Can I make these without alcohol?
Yes! Simply sub the 1 cup of Guinness called for in the recipe for 1 cup of milk. (I recommend 2%) You can omit the 2 tablespoons of alcohol from the frosting as well.
How to make the best Chocolate Frosting:
This frosting is SO incredibly rich and chocolatey. It’s extra creamy, thanks to a combo of butter and cream cheese. I love using both in all my frostings – it helps keep them from having that overly sweet taste that plain buttercream often has.
Add a pinch of espresso powder to enhance the chocolate flavor – it won’t add a coffee taste. A few more splashes of Guinness make this frosting incredibly delicious! If you want to spike your frosting with something else, try Jameson Irish Whiskey or Bailey’s Irish Cream – either of those options would be fabulous, too.
How to frost your cupcakes:
You can frost your cupcakes using a piping bag and tip, or you can swirl and swoop it on with a butter knife or offset spatula. Use whatever option you prefer! I used an Ateco 849 Piping Tip with a piping bag to frost my cupcakes. (Be careful when putting this piping tip in the piping bag. Do NOT let your finger slide into the opening of the piping tip- trust me, it’s painful.)
If you don’t want as much frosting on your cupcakes, cut the frosting recipe in half. But, you will need the full amount if you want to create the large swirls on top.
How long do these last?
In my experience, these are best on the first 1-2 days. Store them in an airtight container in the fridge – the frosting needs to be kept refrigerated. But, let them come to room temp for a bit (30 minutes or so) before serving, so the frosting isn’t so solidified from sitting in the fridge.
And there you have it – the best chocolate cupcakes! I hope you love this recipe as much as we do. Happy baking, and Happy St. Patrick’s Day!
