Chocolate Stout Cupcakes are deep, dark stout beer infused cupcakes, topped with chocolate whipped cream frosting, and a drizzle of stout glaze on top.
Preheat oven to 350° and line cupcake baking pan with cupcake liners.
Using a medium sauce pot, melt butter and add stout. Whisk in cocoa powder and let the mixture get to simmer. When it starts to simmer, whisk and take it off heat.
Cool down the mixture a little bit before adding to the batter or it will scald the eggs.
In a bowl of an electric mixer, add eggs and sour cream and beat until smooth. Beat in sugar and lower the speed to low. Add flour, baking soda, and salt and mix until combined.
Slowly pour in chocolate stout mixture while still on low speed. Let it mix until just combined and scrape sides and bottom of the bowl. Mix just a little bit until everything is combined.
Use an ice cream scoop to get an even amount of batter each time and scoop cupcake batter into each cup, filling it 3/4 of the way full.
Bake cupcakes for 18-20 minutes. You can do a toothpick test to see if the cupcakes are done: insert a toothpick in the center of the cupcakes and see if it comes out clean.
Let cupcakes cool completely before adding frosting.
Stout Glaze:
Make stout glaze while cupcakes are baking because it will need time to cool down.
In a medium sauce pot, combine stout and brown sugar and bring to simmer over medium heat. Make sure not to use a pot that is too small because the beer raises quite a bit while simmering.
Simmer for about 10-15 minutes, until the mixture is reduced enough to thicken and be able to coat the back of a spoon. Cool completely before adding to cupcakes.
Chocolate Whipped Cream:
Use an electric mixer with a whisk attachment. Beat cold heavy whipping cream and cocoa powder starting on low sweet and gradually raising it to high. Pour in sugar while beating the whipped cream.
Keep an eye of the frosting because it will whip fast. Beat it until stiff peaks appear and gradually lower the speed and turn it off.
Keep the frosting refrigerated until ready to frost the cupcakes.
When cupcakes are cooled, frost each cupcake with chocolate whipped cream and drizzle some stout glaze on top.
