Instructions:
- Preheat your oven to 350°F (175°C). Grease your baking pan and line the bottom with parchment paper.

- In a large bowl, beat the granulated sugar, brown sugar, oil, eggs, sour cream, and vanilla until the mixture is smooth and pale.
- Gradually stir the dry ingredients into the wet mixture using a spatula. Mix until just combined.
- Gently fold in the grated zucchini and chocolate chips until evenly distributed.
- Pour batter into the prepared pan and bake for 35 minutes or until a toothpick comes out clean.
- Prepare frosting by beating softened cream cheese and butter until smooth, then mixing in powdered sugar, vanilla, and heavy cream.
- Frost the cooled cake evenly and slice into 12 portions.
