Preheat the oven to 350°F. Place a rack in the center of the oven. Line a 9x5-inch loaf pan with parchment paper and spray the pan and parchment well with nonstick baking spray; set the pan aside.
In a large bowl, sift together 2 and 1/4 cups (270 g) all-purpose flour, 3/4 teaspoon baking soda, 1/4 teaspoon ground nutmeg, 1/2 teaspoon ground cinnamon, and 1/2 teaspoon salt. Set the dry mixture aside.
In a separate large bowl, whisk together the wet ingredients: 1/2 cup (113 g) melted unsalted butter, 2 tablespoons oil, 1/2 cup (106 g) packed light brown sugar, 1/4 cup (50 g) granulated sugar, 2 large eggs (room temperature), 2 teaspoons vanilla extract, 1/4 cup (57 g) milk (room temperature), 1/4 cup (85 g) honey, and 1 and 1/2 cups (340 g) mashed very ripe bananas. Whisk until the mixture is smooth and fully combined.
Pour the dry ingredients into the wet ingredients. Using a rubber spatula, fold the mixture until just combined — stop as soon as there are no large streaks of flour. Do not overmix.
Scrape the batter into the prepared loaf pan and smooth the top with the spatula.
Bake on the center of the middle rack for about 50 minutes, or until the top is a rich golden brown and a toothpick inserted into the center comes out clean or with just a few moist crumbs attached.
Remove the pan from the oven and let the bread cool in the pan for at least 15 minutes.
After cooling at least 15 minutes, lift the bread from the pan using the parchment and either serve warm or transfer to a cooling rack to cool further.
