Make Chocolate Zucchini Cake: Heating of the oven; Bake at 350°F. To do this, grease a 2-quart of any shape with cooking spray and line it with parchment paper and only use a square 8-inch baking pan for this recipe.
Zucchini should be towel-dried and then put to one side. In a large bowl mix the sugars and eggs together for one minute until foamy. Add butter, oil, sour cream and vanilla for the flour mixture. This step will ensure that flour, cocoa powder, baking powder, salt and baking soda are well sieved and mixed together. Whisk until well blended. Fold in zucchini with a rubber spatula and then fold in chocolate chips.
Smooth top of batter in baking pan. It takes 30 to 35 minutes in the oven until a toothpick comes out clean. Let baking pan cool on wire rack for 1 hour.
Make Chocolate Cream Cheese Frosting: Beat butter in a large basin with an electric mixer on medium speed until smooth. Add cream cheese and stir well. Mix confectioners' sugar and salt slowly until combined. Increase speed to medium and mix 1 minute until smooth. Stir in melted chocolate for 30 seconds, being careful not to overbeat.
Remove cake from pan. Cover with frosting and sprinkles. Cover and refrigerate for 3 days.
