Preheat the oven to 350 degrees. Prepare two 8 x 3 inch round pans with nonstick baking spray. Line the bottom of the pans with parchment paper.
Sift together flour, sugar, cocoa, baking soda, baking powder, and salt in a large bowl. In a separate bowl, combine buttermilk, oil, eggs, and vanilla. Slowly add the wet ingredients to the dry ingredients while mixing on low speed. Mix in the coffee until well combined. Pour the batter into the prepared cake pans. Bake for 30-40 minutes or until a toothpick inserted comes out clean. Let the cakes cool in the pans for 30 minutes, then transfer to a cooling rack.
Whisk milk and flour in a saucepan, then cook until thickened. Remove from heat and add vanilla extract. In a separate bowl, cream butter and sugar until fluffy. Slowly add the milk mixture and beat until creamy.
Place chocolate chips in a bowl. Heat the heavy cream until simmering, then pour over the chocolate chips. Allow the mixture to sit for 2 minutes until the chocolate melts and thickens.
Place one cake layer on a plate. Spread the filling over the layer. Top with the second cake layer and refrigerate until chilled. Pour the ganache over the cake and spread evenly.
