I’ve had my eye on this recipe for a few months now and was so excited about St. Patrick’s Day just to try it out. Plus, I just got purchased The Best Ever Cupcake Icing Kit from Bake it Pretty and couldn’t wait to use it.
See! Isn’t it cute? It was so easy decorating the cupcakes with the jumbo tips.
These cupcakes have have a chocolate-y, slightly Guiness-y taste to them. The recipe called for Dutch-processed cocoa powder but I didn’t have any, so I substituted that for unsweetened cocoa powder. I was a little worried that the cupcakes would be ruined because unsweetened cocoa powder has a strong chocolate taste and is acidic , which could have had a really bad chemical reaction with the baking soda. Not bad as in exploding cupcakes bad, but bad as in yucky-tasting cupcake bad.
Luckily, the cupcakes came out great. They were really moist and fluffy and the Guinness taste wasn’t strong at all. My favorite part was the Bailey’s infused frosting. I’ve always loved Bailey’s Irish Cream and this frosting did not disappoint at all.
Don’t wait until St. Patrick’s Day rolls around next year, try these ASAP.
