If you will notice, this is not a regular chocolate cake, I used whole wheat flour and bananas plus some chia seeds which makes it better nutritionally. ;)
In a large bowl whisk together the sugar, flour, cocoa powder, baking powder, baking soda, and salt and chia seeds if using. Set aside.
In another large bowl, whisk together the eggs, mashed bananas, water, milk, oil, and vanilla extract.
Add the wet ingredients to the dry ingredients and stir, or whisk, until combined.
Pour the batter into the prepared 8inch baking dish and bake for about 35 to 40 minutes or until a toothpick inserted in the center of the cake comes out clean.
Remove from oven and let cool on a wire rack.
When completely cooled, frost with ganache.
FOR THE GANACHE:
Put grated chocolate and coffee powder if using in a bowl, set aside.
Heat cream in a saucepan just until it begins to boil, immediately pour heated cream to the chocolate.
Stir until smooth.
Cool a bit then pour on top of cooled cake.
