Pre-heat oven to 325*F.
In a bowl, whisk together the dry ingredients including; almond flour, coconut flour, arrowroot starch, baking powder, baking soda, cinnamon, nutmeg, allspice, ginger, xanthan gum and salt.
In another larger bowl, whisk together the coconut oil and sweetener until smooth.
Add the eggs, heavy cream, pumpkin, vanilla extract and vinegar and whisk very well.
Add the dry ingredients to the wet and stir until a thick batter forms.
Grease an 8x8 inch pan.
Scrape the batter into the pan and use your hands or a spatula to spread it around and cover the bottom evenly.
Top with roasted pumpkin seeds.
Bake the cake for 28-35min or until a toothpick comes out almost completely clean and the top is lightly browned. The centre will also no longer be jiggly.
Let it cool completely before slicing. You can also top it with a little extra powdered monkfruit sweetener at this time. Serve and enjoy your Keto Pumpkin Spice Cake!
