In a large bowl, whisk together the eggs, oil, honey, and vanilla until smooth.
2 large (100 g) eggs, ¾ cup (180 ml) vegetable oil, ¾ cup (255 g) honey, 2 tsps (10 ml) vanilla extract
In a separate bowl, stir together the flour, baking powder, cinnamon, nutmeg, salt, and baking soda. Add the dry ingredients to the wet and stir until just combined. Fold in the zucchini and mix well.
2 cups (240 g) all-purpose flour, 2 tsps (8 g) baking powder, 2 tsps (5 g) ground cinnamon, 1 tsp (2 g) ground nutmeg, ½ tsp (3 g) table salt, ¼ tsp (1.25 g) baking soda, 2 cups (260 g) grated zucchini
Pour the batter into the prepared pan and smooth the top. Bake for 55 to 65 minutes, or until a toothpick inserted in the center comes out clean. Let cool in the pan for 10 minutes, then transfer to a wire rack to cool completely.
To make the glaze, whisk together the confectioners’ sugar, milk, and melted butter until smooth and drizzle over the cooled loaf. Let the glaze set before slicing and serving.
