Preheat oven to 350 degrees F. Lightly grease an 8" springform pan and line the bottom of the pan with parchment paper.
In a medium mixing bowl, combine the dry ingredients.
2 ½ cups (240g) almond flour, ½ cup plus 2 tablespoons tapioca flour, 1 ½ teaspoons pumpkin pie spice, ½ teaspoon cinnamon, 2 teaspoons baking powder, ½ teaspoon fine sea salt
In a large mixing bowl, whisk together the pumpkin, eggs, coconut sugar, oil, and vanilla.
1 cup canned pumpkin, 3 eggs, room temperature, 1 cup coconut sugar, 3 tablespoons avocado oil , 2 teaspoons pure vanilla extract
Pour the dry ingredients into the bowl with the wet ingredients and mix until just combined. Don't over mix.
Pour the cake batter into the prepared baking pan and smooth out the top of the cake.
Bake for 35-40 minutes, or until the center of the cake is firm to the touch and a toothpick inserted in the center comes out clean. Using a digital thermometer is the best way to check doneness. The cake should be 200-205 degrees F when done.
Allow to cool for a minimum of 15 minutes before removing the side from the springform pan. You can keep the cake on the bottom of the springform pan to finish cooling. If frosting, allow cake to fully cool before frosting.
If adding the frosting, make the the frosting by adding all ingredients to a mixing bowl. Using an electric hand-mixer, beat on medium until smooth and creamy. Spread frosting on cake.
8 oz. cream cheese, room temp, ¼ cup plain Greek yogurt, 3 tablespoons pure maple syrup, 1 teaspoon pure vanilla extract
Cake should be stored in the fridge and is best when slightly chilled. Remove from the fridge about 30 minutes before serving.
