These St. Patrick's Day Cupcakes Are Made With... Beer!

Beer might not be an ingredient that you expect to bake with but, hey, it's St. Patrick's Day! And the rich taste of Guinness actually pairs really nicely with the chocolate in these cupcakes. Finish 'em off with a swirl of icing and some festive decorations, and it's most definitely your lucky day.

1. Do the Prep

Preheat the oven to 350 F. Line a 12-cup baking tin with paper liners.

2. Combine Dry Ingredients

Sift together all purpose flour, cocoa powder, baking soda and salt in a medium bowl.

3. Make the Batter

In a large bowl, cream together butter and sugar until light and fluffy. Blend in egg. Stir in half of the flour mixture, followed by the Guinness, buttermilk and vanilla extract. Stir in the remaining flour mixture, mixing until no streaks of dry ingredients remain. Divide batter evenly into prepared muffin cups.

4. Bake and Cool

Bake for 15-18 minutes, until a toothpick inserted into the center of a cupcake comes out clean. Cool the cupcakes in the pan for 2-3 minutes, then turn them out on to a wire rack to cool completely before frosting.

Pro Tip

These cupcakes are very moist and will keep well for several days after baking. Just store 'em in an airtight container!

5. Color Your Piping Bag

To make the cool stripe of green in the icing, we used what's called the painted bag method . Using tape, attach a food-safe paint brush to a wooden skewer, making a very long paint brush handle. Squirt some green gel food coloring onto the inside top of your piping bag (it should already be fitted with your large, open-star tip at this point), and use the paint brush to drag the gel down towards your tip so you have a stripe of green down one side. Then, carefully fill the bag with Swiss Meringue Buttercream.

6. Pipe the Swirls

Practicing on parchment paper first — sometimes it takes a few tries before your green stripe shows up! — frost each of your cupcakes with a high swirl of icing .

7. Get a Little Lucky

To add some extra St. Patrick's Day fun, roll out green fondant and cut four small heart shapes for each cupcake. Dust each cupcake with gold luster, then arrange the hearts in the shape of a four-leaf clover on top of each treat. Finish with an extra sprinkle of gold pearlized sugar, for good measure!

Irish coffee was invented in — you guessed it — Ireland nearly 80 years ago, when a local chef decided that coffee is even better with a little something extra thrown in to take the chill off. (Irish whiskey, to be specific.)
