Preheat oven to 350F. Spray your 9x13 pan with baking spray.
In a large bowl whisk together the sugar, coffee, oil, cocoa powder, vinegar, vanilla and salt.
Whisk in the baking soda, and then the flour. The batter will be thin.
Turn the batter into your prepared pan and give it a rap on the counter to bring bubbles to the surface.
Bake for 30 minutes. This cake bakes fast, so be careful not to over bake. The center will feel firm and a toothpick inserted in the center will come out without wet batter on it (moist crumbs are fine.) Put the cake on a rack to cool.
After the cake has cooled for at least 30 minutes, make the ganache. Put the chocolate in a heatproof bowl. Scald the cream and corn syrup in a saucepan and then pour over the chocolate. Let sit for a few minutes, then stir to melt the chocolate and create the silky ganache. Stir in the vanilla.
Pour the ganache over the warm cake and spread out with an offset spatula. Allow the ganache to set up before slicing.
Leftover cake can be kept on the counter or refrigerated.
