01 - Preheat your oven to 350°F (175°C). Grease and line a 9x5-inch (23x13 cm) loaf pan with parchment paper.
02 - In a medium bowl, whisk together flour, baking powder, baking soda, salt, cinnamon, nutmeg, and cloves.
03 - In a large bowl, whisk melted butter, maple syrup, brown sugar, eggs, milk, and vanilla extract until smooth.
04 - Gradually fold the dry ingredients into the wet mixture until just combined; do not overmix.
05 - In a small bowl, mix together the chopped pecans, brown sugar, cinnamon, and maple syrup for the swirl.
06 - Pour half of the batter into the prepared loaf pan. Sprinkle half of the pecan mixture evenly over the batter. Pour in the remaining batter and top with the rest of the pecan swirl.
07 - Use a knife to gently swirl the pecan mixture through the batter.
08 - Bake for 48–55 minutes, or until a toothpick inserted into the center comes out clean. If the top browns too quickly, tent loosely with foil after 35 minutes.
09 - Cool the bread in the pan for 15 minutes, then transfer to a wire rack to cool completely before slicing.
