Preheat the oven to 350°F (175°C). Grease the loaf pan with non-stick spray or line it with baking parchment for easy removal.
In a mixing bowl, combine the almond flour, erythritol, baking powder, baking soda, ground cinnamon, ground nutmeg, salt, and ground ginger. Whisk well to combine the dry ingredients.
In another bowl, whisk together the pumpkin puree, eggs, vanilla extract, and melted coconut oil until smooth.
Pour the wet ingredients into the dry ingredients. Using a rubber spatula, mix until just combined. Do not overmix.
Transfer the batter into the prepared loaf pan, smoothing the top with the spatula.
Bake in the preheated oven for about 45-50 minutes, or until a toothpick inserted in the center comes out clean.
Once done, remove the bread from the oven and let it cool in the pan for about 10 minutes. After that, transfer it to a wire rack to cool completely before slicing.
