Preheat the Oven and Prepare the Baking Pan - Preheat your oven to 350 degrees Farenheit. Spray your 8×4-inch baking pan with cooking spray.
Shred Zucchini - Using a grater, shred your zucchini. Once shredded, blot the excess water from the zucchini using paper towels.
Combine Dry Ingredients - In a large mixing bowl, combine the all-purpose combine flour, baking powder, baking soda, cinnamon, cloves, and salt using a whisk.
Mix Together with the Wet Ingredients and Sugar Substitute - In a medium bowl, whisk together the baking sugar substitute, milk, egg, butter, and vanilla extract. Then, mix in your shredded zucchini.
Combine the Dry Ingredients and Wet Ingredients - Combine your dry ingredients with the wet ingredients. Mix together until fully combined. The batter will be slightly lumpy.
Bake the Zucchini Bread - Pour the batter into the prepared cake pan. Bake for nearly 35-45 minutes, or until a toothpick inserted into the middle, comes out clean. Allow the zucchini bread to cool for 10 minutes in the pan before transferring to the wire rack.
