Preheat the oven to 350°F (180°C) and line an 8x8-inch baking pan with baking paper.
In a large mixing bowl, combine the almond flour with the Erythritol, cacao powder, baking powder, pumpkin pie spice, and a tiny pinch of sea salt.
In another bowl, combine the pumpkin puree with the eggs and coconut oil.
Combine the two mixtures together and mix well.
Pour the mixture into the prepared baking pan and bake for about 20-25 minutes.
Allow the brownie to cool in the pan before slicing and serving at room temperature.
