This is the best Chocolate Zucchini Cake, ever. Totally moist, full of amazing flavor, and destined to be your go-to recipe!
In a large mixing bowl, beat together the butter, oil, sugar, vanilla, baking soda, baking powder, and salt until smooth.
Bake the cake for 30 to 35 minutes, until the top springs back lightly when touched, or center no longer appears wet.
Place the chocolate into a medium bowl. Heat the cream in a small sauce pan over medium heat. Bring just to a boil, watching very carefully so that it does not boil over.
