Preheat the oven to 400℉ and line a muffin pan with liners. It makes about 18-20 muffins.
Mix all dry ingredients in one bowl. Set aside.
2¾ cup All-purpose flour, 1½ teaspoon Baking soda, ½ teaspoon Baking powder, ½ teaspoon Salt, 1½ teaspoon Cinnamon, ½ teaspoon Ginger
Add the chopped pecans and mix.
¾ cup Pecans
In a separate bowl, mix the sugar, pumpkin puree, eggs, oil, Bourbon, and vanilla extract.
2 cups Granulated sugar, 1½ cups Pumpkin puree, ¾ cup Oil, 3 Eggs, ¼ cup Bourbon
Make a well in the center of the dry ingredients, add the wet, and mix until there are no streaks of dry ingredients. Do Not Overmix.
Fill up the muffin cups to the top. Spread about one tablespoon of the sugar mix on top of each muffin and gently press the mixture down. Bake the muffins for 5 minutes at 400℉, then reduce the heat to 350℉ and bake them for another 20-25 minutes. Let them cool down in the pan, then transfer to the cooling rack to cool down completely.
