Preheat oven to 350 degrees. Lightly grease two 9x5" loaf pans
In a microwave-safe bowl, microwave chocolate squares, stirring occasionally, until melted and smooth.
In a large bowl, combine eggs, sugar, oil, zucchini, vanilla, and chocolate. Beat well.
In a separate bowl, whisk flour, baking soda, salt, and cinnamon. Then stir flour into wet mixture. Once just combined, fold in chocolate chips. Pour batter into prepared loaf pans.
Bake in a preheated oven at 350 degrees for 60-70 minutes, or until a toothpick inserted into the center of a loaf comes out clean. Makes 2 loves. Enjoy!
