Stout Out Loud!

Chocolate Stout Cupcakes with Chocolate Espresso Buttercream Frosting
 It was my beloved's birthday last week and it was time to celebrate! When I asked Matt what he wanted to do for his birthday, he responded without hesitation: "Power Hour." Power Hour, if you are not familiar, is an exercise power drinking - taking a shot of beer every minute for 60 minutes. It's become a bit of a birthday tradition for Matt - much like my own birthday marathon (involving running rather than drinking). To go along with the evening's centerpiece activity, I decided to develop a couple of beer-themed recipes including sweet and smoky beans slow-cooked in beer and, of course, a beer-themed dessert. The result was a moist, chocolatey, and subtly sweet cupcake with a fluffy buttercream topping. These were definitely a hit for chocolate and beer-lovers alike.

Ingredients
CHOCOLATE STOUT CUPCAKES
- 4 oz. unsweetened chocolate, melted and cooled
- 2 c. sugar
- 12 oz. dark chocolate stout (such as Guinness)
- 1 tsp. salt
- 1 tsp. baking soda
- 4 eggs
- 1 stick butter, melted
- 2 tsp. vanilla
- 2 c. flour
- 1 c. sour cream

CHOCOLATE ESPRESSO BUTTERCREAM FROSTING
- 1 c. sugar
- 3 large egg whites
- 1/4 tsp. salt
- 1 Tbsp. pure vanilla extract or vanilla paste
- 2 sticks plus 2 Tbsp. unsalted butter, at room temperature, cut into tablespoons
- 4 oz. extra-bittersweet chocolate, melted and cooled
- 2 Tbsp. espresso powder

CHOCOLATE STOUT CUPCAKES
Preheat over to 350F˚ and line a cupcake tin with paper liners. Spray very lightly with vegetable spray, set aside.

In a medium bowl, whisk together flour, baking soda, and salt. Set aside.

In a large bowl blend together melted butter, sugar, vanilla, and melted chocolate with an electric mixer until well blended. Scrape down the sides of the bowl with a spatula and add stout. Mix thoroughly on medium-high.

Scrape down the sides of the bowl again and add eggs, one at a time, alternating with portions of flour mixture with the machine running on medium. When the mixture is well combined, add sour cream until just mixed. Spoon batter into prepared cupcake liners until they are 2/3 of the way full. Bake in batches in oven for 12-15 minutes until the cupcakes are cooked through and springy.

Allow to cool completely on a rack before frosting.

CHOCOLATE ESPRESSO BUTTERCREAM FROSTING
Whisk together eggs whites and sugar in a medium-sized double-boiler. Place the double-boiler over medium-high heat and whisk together over heat until the sugar is dissolved, about 5 minutes.

Transfer the warmed egg and sugar mixture to the bowl of a stand mixer with a whisk attachment. Add vanilla and whisk together at medium-high heat until the mixture is glossy and stiff, about 8 minutes. Scrape down the sides of the bowl and turn mixer back on to medium heat. Add butter, a couple pieces at a time making sure the mixture becomes fully incorporated before adding more. Once all the butter is incorporated and mixture is light and fluffy, add melted chocolate and espresso powder and mix until fully blended. 

Frost cooled cupcakes with an offset spatula. Buttercreams can be delicate, store frosted cupcakes in the refrigerator if making ahead of time. Allow to sit at room temperature for about 20 minutes before serving.
