Preheat the oven to 350°F (175°C) and grease a 9-inch round cake pan.
In a large bowl, combine the mashed sweet potatoes, almond flour, coconut sugar, melted coconut oil, eggs, ground ginger, baking powder, salt, and vanilla extract.
Mix until well combined and smooth.
Pour the batter into the prepared cake pan and spread evenly.
Bake for 30-35 minutes or until a toothpick inserted in the center comes out clean.
Allow the cake to cool in the pan for 10 minutes before transferring to a wire rack to cool completely.
Notes
