In a spacious blender, combine the eggs, pumpkin puree, sweetener, and vanilla extract. Blend until the mixture is smooth and well combined.
Next, add the almond flour, protein powder, baking powder, pumpkin pie spice, and salt. Blend again until everything is fully incorporated.
Pour in the almond milk and melted butter, then blend one last time. Let the batter rest for 5 minutes; this helps it thicken up nicely.
While the batter rests, preheat your waffle iron and lightly grease its plates.
Once your waffle iron is hot, pour about 1/4 cup of batter into each section, spreading it gently to the edges.
Close the lid and cook until the waffles turn a beautiful golden brown. Cooking time will vary based on your waffle iron.
Carefully remove the cooked waffles and place them on a wire rack. Repeat with the remaining batter until all waffles are made.
Serve your delicious waffles topped with a pat of butter, sugar-free pancake syrup, or a dollop of lightly sweetened whipped cream and a sprinkle of cinnamon for an extra treat!
