Preheat the oven to 350℉ (180℃). Grease and line a 9x13-inch baking pan with parchment paper. Set aside.
Add almond flour, low-carb granulated sweetener, baking soda, baking powder, salt, pumpkin pie spice, and cinnamon to a large mixing bowl. Whisk until thoroughly combined.
Add pumpkin puree, avocado oil, eggs, and vanilla extract to the dry mixture. Mix until smooth and combined.
Pour the cake batter into the prepared pan and spread until level and even.
Bake for 40-45 minutes or until a toothpick comes out clean from the center of the cake.
Remove the cake from the oven and let it cool completely.
Add cream cheese, butter, vanilla extract, and half of the powdered sweetener to a stand mixer or large mixing bowl with a hand mixer and beat on medium speed until combined. Add the remaining sweetener and two tablespoons of the almond milk and beat until creamy. You can add more almond milk to thin the frosting if needed.
Once the cake has cooled completely, frost it with the cream cheese frosting, cover, and refrigerate for 2 hours or more before serving. Slice and serve.
