Step 1: Preheat your oven to 350°F (175°C). Grease a 9×5 inch loaf pan and line it with parchment paper for easy removal.
Step 2: In a medium bowl, whisk together the flour, baking powder, baking soda, cinnamon, ground ginger, and salt. Set aside.
Step 3: In a large bowl, cream together the softened butter, brown sugar, and granulated sugar until light and fluffy, about 3-4 minutes.
Step 4: Beat in the eggs one at a time, then stir in the vanilla extract.
Step 5: Fold in the grated zucchini and chopped dates until evenly distributed in the wet mixture.
Step 6: Gradually add the dry ingredients to the wet ingredients, stirring gently until just combined. Do not overmix.
Step 7: Pour the batter into the prepared loaf pan and smooth the top with a spatula.
Step 8: Bake for 50-60 minutes, or until a toothpick inserted into the center comes out clean or with just a few moist crumbs.
Step 9: While the loaf is baking, prepare the ginger sauce by combining the heavy cream, brown sugar, butter, grated ginger, and salt in a small saucepan over medium heat.
Step 10: Bring the sauce to a gentle simmer, stirring constantly, and cook for 5-7 minutes until slightly thickened. Remove from heat.
Step 11: Allow the loaf to cool in the pan for 15 minutes before transferring to a wire rack. Serve warm slices with plenty of ginger sauce drizzled over the top.
