Preheat the oven to 350 degrees Fahrenheit and line a 8-inch spring form cake pan with a circle of parchment paper. Spray the sides of the cake pan with cooking oil.

Mix the eggs, pumpkin puree, pure maple syrup, avocado oil, grated ginger, and pure vanilla extract (wet ingredients) in a large mixing bowl until well combined.

In a separate bowl, stir together the almond flour, baking powder, pumpkin pie spice, and sea salt (the dry ingredients). Mix the dry ingredients into the bowl with the wet ingredients until a thick batter forms.

Spread the cake batter into the prepared pan into an even layer. Cover the pan with aluminum foil. Bake on the center rack of the preheated oven for 40-45 minutes, or until the cake is fully baked.

Insert a digital thermometer into the center of the cake to check its internal temperature. It is ready if it is 190 degrees Fahrenheit or higher.

Allow the cake cool completely to room temperature before slicing and serving.
