01 - Preheat oven to 350°F. Arrange paper liners in a 12-cup muffin tin or lightly grease the cups.
02 - In a large mixing bowl, whisk together flour, baking powder, baking soda, salt, cinnamon, nutmeg, ginger, and cloves thoroughly.
03 - In a separate bowl, whisk vegetable oil, light brown sugar, eggs, pumpkin puree, and vanilla extract until smooth and fully blended.
04 - Gently stir wet ingredients into the dry mixture until just combined, avoiding overmixing.
05 - Evenly distribute the pumpkin batter among muffin cups, filling each approximately two-thirds full.
06 - In a medium bowl, mix chopped pecans, light brown sugar, maple syrup, melted butter, egg, vanilla extract, and a pinch of salt until fully incorporated.
07 - Spoon 1 to 2 tablespoons of pecan topping onto each muffin, gently spreading to cover the surface.
08 - Bake for 25 to 30 minutes, or until a toothpick inserted in the pumpkin portion comes out clean. Avoid testing through the pecan topping.
09 - Allow to cool in the pan for 10 minutes, then carefully transfer muffins to a wire rack to cool completely before serving.
