Toast the pecans in a dry skillet over medium heat for about 5 minutes, stirring frequently until fragrant and darker in color. Remove and let cool.
In a large mixing bowl, whisk together the flour, baking powder, and salt until evenly combined.
In a separate bowl, mix the melted butter, maple syrup, eggs, and vanilla extract until smooth and slightly frothy.
Pour the wet mixture into the dry ingredients and gently fold with a spatula until just combined; avoid overmixing to keep the bread tender.
Chop the toasted pecans and fold them into the batter, distributing evenly for crunchy layers and nutty bursts in each slice.
Pour the batter into a greased 9x5-inch loaf pan, smoothing the top with a spatula and sprinkling a few pecans on top for garnish.
Bake in a preheated oven at 175°C (350°F) for 55-60 minutes, until the crust is golden and a toothpick inserted in the center comes out clean.
Remove the bread from the oven and allow it to cool in the pan for 10 minutes, then transfer to a wire rack to cool completely, which helps set the crumb.
Slice and enjoy the bread slightly warm or at room temperature, revealing layers of crunchy pecans and moist crumb infused with maple aroma.
