Preheat oven to 350°F (175°C) and grease a 9x13 inch baking pan with coconut oil or parchment paper.
In a medium bowl, whisk together the whole wheat flour, baking soda, baking powder, cinnamon, ginger, cloves, and salt.
In a large bowl, combine the pumpkin puree, maple syrup, eggs, melted coconut oil, and vanilla extract until smooth.
Gradually fold the dry ingredients into the wet ingredients until just combined, ensuring no flour streaks remain.
Spread the batter evenly into the prepared baking pan using a spatula.
Bake for 22 to 25 minutes or until a toothpick inserted into the center comes out clean.
Allow the bars to cool completely in the pan on a wire rack before slicing into 16 squares.
