Preheat oven to 350 degrees F (175 degrees C). Grease and flour a 9 inch round cake pan.
In a medium bowl, sift together the flour, baking soda, baking powder, salt and cocoa powder. Set aside.
In a large bowl, combine the coffee, buttermilk, oil, vanilla and sugar. Beat in the eggs one at a time. Gradually beat in the sifted ingredients until just blended. Stir in the chocolate chips.
Pour the batter into the prepared pan and bake for 30 to 35 minutes, or until a toothpick inserted into the center of the cake comes out clean.
Let the cake cool in the pan for 10 minutes, then turn out onto a wire rack and cool completely.
