Preheat the oven to 350˚F (175˚F C). Grease a 9x5-inch loaf pan. Line the pan crosswise with a piece of parchment paper that extends a couple inches over the sides (this will allow you to easily pull the cooked loaf out of the pan later).
In a large bowl, combine the pumpkin, coconut sugar, cinnamon, nutmeg, ginger, cloves, vanilla, salt and eggs. Whisk until smooth.
In a medium bowl, whisk together the almond flour, arrowroot powder and baking powder. Use your fingers to break up any lumps of almond flour. Pour the dry ingredients over the pumpkin mixture and whisk until evenly incorporated (don’t over-mix). Stir in ⅓ cup chopped pecans, if using.
Scrape the batter into the loaf pan and spread it in an even layer. Sprinkle the top with the remaining 2 tablespoons of chopped pecans (if using). Bake until golden brown on top (it will crack), about 45-50 minutes (it takes 47 minutes in my oven). Place the pan on a wire rack and let it cool for 10 minutes.
Run a small knife along the edges of the loaf pan, then use the parchment handles to remove the bread from the pan. Let the bread cool completely on a rack (it’s important that it cools completely before slicing for the best texture and flavor!).
Slice the pumpkin bread and serve it on its own or with softened butter. Swoon!
