Story Behind this Recipe
I added chocolate to Recipe ID: 1370658.
I used a Panasonic Home Bakery bread machine. Your bread machine may differ, so follow the instructions for baking cakes. By scraping down the flour on the inside of the pan halfway through, the surface of the cake will bake nicely and evenly.
