1. Pour the beer into a 1 quart saucepan set over medium high heat. Bring the beer to a boil, then reduce heat to medium-low and cook for 20 - 30 minutes, or until the beer has reduced to ½ cup in volume.


2. Preheat the oven to 350 degrees F. Then, line an 8x8 pan with parchment paper. Set aside.


3. Meanwhile, add the flour and cocoa powder to a mixing bowl, whisking with a wire whisk or sifting with a fine mesh strainer to remove any clumps of cocoa. Set aside.


4. Then, melt the butter in 2 qt saucepan over medium-low heat. When the butter has melted, add the sugar, espresso powder, salt, and vanilla extract.
