Whisk all the dry ingredients together well in a large bowl.
In a separate bowl, whisk together all the wet ingredients EXCEPT the coffee.
Slowly add the wet ingredients to the dry ingredients, mixing as you go. Once incorporated, add the hot coffee, and mix everything until there are no pockets of dry flour left. The batter will be very thin.
Turn the batter into your prepared pan and bake for 35 minutes until risen and a toothpick inserted into the center of the cake comes out without wet batter clinging to it.
For the frosting
Melt the butter, chocolate, and salt in a medium heavy bottomed saucepan over low heat. Add in the sugar and milk and bring up to a boil.
Lower the heat and cook for about 6 minutes, stirring constantly. Remove from heat and stir in the vanilla.
Pour the hot fudge sauce over the cake and spread out with an offset spatula. Allow to set for about 10 minutes before slicing.
Store leftover cake in the refrigerator for up to 4 days.
Notes
*You may have extra hot fudge sauce, depending on how thickly you want to coat your cake. No worries, you can use it on ice cream, or over pound cake, or just finish it up with a spoon!
