Preheat your oven to 350°F (175°C).
In a medium bowl, whisk together the coconut flour, arrowroot flour, ground cinnamon, ground ginger, ground cloves, baking soda, and a pinch of salt.
In a large bowl, mix the mashed pumpkin or squash with melted coconut oil and honey or maple syrup until well combined.
Gradually add the dry ingredients to the wet mixture, stirring until fully combined. The batter should be thick but moist.
Pour the batter into a greased or parchment-lined loaf pan and smooth the top with a spatula.
Bake for 50-60 minutes, or until a toothpick inserted into the center comes out clean.
Allow the bread to cool in the pan for 10 minutes, then transfer to a wire rack to cool completely.
