How to make
In a large bowl mix the flour, sugar, cocoa, baking soda, baking powder and salt. Stir nicely and make a hole in the middle. Inside, pour the brewed coffee, milk, eggs and vanilla.
Beat with a mixer on medium speed for 2 minutes, and pour it into the prepared baking container. Bake 30-40 minutes at 360°F (180 C). When the cake is done, allow it to cool and make the glaze.
Mix the butter, chocolate (broken into blocks) and coffee and put them in a water bath until completely thawed. Pour this glaze over the cake.
