Double Irish Cheer ~ Stout and Whiskey Cupcakes

What’s even more Irish than chocolate Guinness cupcakes? Chocolate Guinness cupcakes topped with Irish whiskey frosting! I wanted to make one more round of cupcakes for the day. 🙂 These cupcakes celebrate two of the most famous flavors of Ireland – stout and whiskey.

I love how versatile the frosting I made in the last blog entry can be. It is a classic 7-minute frosting, which is fluffy and meringue-like. Unlike most frosting, this one is quite a bit lighter with no butter or cream. It is wonderful to work with and pipes beautifully. It doesn’t hold as well over time as a buttercream, so make it shortly before you need it, but it stays together for a few hours. I was so interested and excited about this frosting that I played with the recipe by making small batches in different flavors that I thought may pair well with the chocolate Guinness cupcakes. I made a sparkling wine frosting, a Harp beer frosting, and even an IPA beer frosting! But I settled on this Irish whiskey frosting to top one more batch of cupcakes for St. Patrick’s Day. This flavor was my pot of gold at the end of a rainbow of flavors. 😉

Stout and Whiskey Cupcakes

Makes about 24 standard-sized cupcakes

For the cupcakes:

1 cup Guinness stout

1/2 cup light olive oil

2 tablespoons skim milk

3/4 cup reduced-fat sour cream

2 eggs, beaten

1 teaspoon vanilla extract

3/4 cup unsweetened cocoa powder, sifted

1 1/4 cups granulated sugar

2 cups whole-wheat pastry flour

2 1/2 teaspoons baking soda

For the frosting:

1 cup granulated sugar

1/4 teaspoon cream of tartar

1/4 cup water

4 egg whites

Pinch of salt

3 tablespoons Irish whiskey (I used Jameson)

For the cupcakes:

Preheat oven to 350 F. Line 2 muffin tins with cupcake liners.

In a medium bowl, whisk together the stout, oil, milk, sour cream, eggs, and vanilla until everything is very well combined.

In a large bowl, whisk together the cocoa powder, sugar, flour, and baking soda.

Add the wet mixture in the medium bowl to the dry mixture in the large bowl, and whisk until just combined.

Divide the batter between the muffin tins, filling each cup about 2/3 full.

Bake for about 20 minutes, or until a toothpick inserted into the center of a cupcake comes out clean.

Let cool completely before frosting.

For the frosting:

Find a big pot in which the bowl of a stand mixer can fit inside without touching the bottom. Fill the pot with about 2 inches of water. (Take care that the water doesn’t touch the bottom of the bowl.) Bring the water to a simmer.

In a small bowl or measuring cup, mix the sugar and cream of tartar. In the bowl of the stand mixer, add all of the frosting ingredients except for the whiskey, and whisk until combined.

Place the bowl over the pot of simmering water. Attach a candy thermometer to the side of the bowl. Whisking often, let the mixture come up to 160 F. It will look a little frothy.

Once the mixture is at 160 F, remove the bowl from the pot and place it on the stand mixer fitted with a whisk attachment.

Whisk on high speed for about 7 minutes, or until the mixture is fluffy, cool, and very stiff. Add the whiskey, and whisk until just combined.

Pipe or spoon the frosting onto your cupcakes.
