Stout Cake Coffee Frosting (Print Version)

# Ingredients:

→ Chocolate Stout Cake Base

01 - 1 cup dark cocoa powder
02 - 1½ cups of cold unsalted butter
03 - 1 teaspoon table salt
04 - 1½ cups stout beer (try Guinness)
05 - ⅔ cup sour cream, unsweetened
06 - 1½ teaspoons of vanilla flavoring
07 - 3 cups regular granulated sugar
08 - 2¼ teaspoons baking powder
09 - 3 cups plain white flour
10 - 3 fresh large eggs, room temperature

→ Coffee Frosting

11 - 1 tablespoon water, just enough for dissolving
12 - 1½ tablespoons powdered espresso
13 - 1 teaspoon vanilla essence
14 - 1½ cups of softened butter
15 - Chocolate sprinkles for decoration (optional)
16 - 2 cups powdered sugar

# Instructions:

01 - In a pan, warm up the butter and stout beer until melted and just about to bubble. Stir in the cocoa powder until it’s smooth. Leave it alone until it cools completely.
02 - Whisk sour cream, eggs, and vanilla in a bowl. Separately, mix the dry ingredients together. Combine the wet ingredients with the cooled beer blend, then carefully stir in the dry mixture until it’s smooth.
03 - Divide the batter into two round 9-inch pans. Bake at 350°F for around 35-38 minutes. When done, leave the layers to cool fully.
04 - Beat butter and sugar together until it's light and fluffy. Dissolve espresso powder in the water, then blend it in with vanilla essence until mixed well.
05 - Spread frosting between the layers. Use more frosting to cover the top and sides. Toss on some chocolate sprinkles if you feel fancy.

# Notes:

01 - Make sure the 9-inch pans are 2 inches deep or more
02 - Inspired by a King Arthur Flour idea
03 - Includes alcohol from the stout beer
