Get your blender ready! Toss in the eggs, pumpkin puree, sweetener, and vanilla extract. Blend until it's super smooth.
Next, add the almond flour, protein powder, baking powder, pumpkin pie spice, and salt. Blend again until everything is well combined.
Pour in the almond milk and melted butter, and give it one last blend. Let the batter chill for 5 minutes; it helps it thicken up perfectly.
While your batter rests, preheat your waffle iron. Give the plates a light greasing to prevent sticking.
Once the iron is hot, scoop about 1/4 cup of batter into each section, spreading it gently to the edges.
Close the lid and cook until your waffles are beautifully golden brown and crispy. Cooking time varies by waffle iron!
Carefully remove the cooked waffles and place them on a wire rack to keep them crisp. Repeat with any remaining batter.
Serve these healthy, protein-packed waffles warm! Enjoy them with a pat of butter, sugar-free syrup, or a dollop of light whipped cream and a sprinkle of cinnamon for an extra treat.
