In a large bowl combine flour, cocoa powder, sugar, baking soda, baking powder, and salt.
Add the milk, eggs, coffee, vanilla, and oil. Beat on medium speed for 1-2 minutes to combine.
Divide the batter between two greased cake pans. Bake until a toothpick inserted into the center of the cake comes out with just a few crumbs.
Heat heavy cream in a small saucepan. Pour cream over chocolate chips in a small bowl. Cover with a plate for 2-3 minutes to contain the heat and allow the chocolate chips to soften.
Pour about ½ cup of the ganache over the top of one cake layer and spread just to the edges to form the filling. Stack the second cake layer, top down, onto the ganache layer.
Pour additional ganache over the top of the cake. Use an offset spatula to smooth the ganache down and around the sides.
