Preheat the Oven: Warning: stage your oven at 350°F/175°C. Fill a muffin tin with silicone or paper liners.
Mix Wet Ingredients: In a big bowl, combine the pumpkin puree, eggs, melted butter (or oil) and vanilla extract, and beat until the mixture is smooth.
Combine Dry Ingredients: In a separate bowl, stir together almond flour, erythritol, baking powder, baking soda, cinnamon, nutmeg, ginger and salt.
Combine Both Mixtures: Gradually stir in dry ingredients. Stir until just combined. Do not overmix.
Add Extras (Optional): Stir in sugar-free chocolate chips or chopped nuts, if using.
Fill Muffin Cups: Spoon the batter equally into the muffin liners, about ¾ full.
Bake: Bake for 18–22 minutes, or until the muffins are golden and a toothpick inserted in the center comes out clean.
Cool and Serve: Let cool about 5-10 minutes in the pan, then transfer to a wire rack to cool completely.
