Preheat your mini waffle maker for 3 minutes.
In a mixing bowl, whisk the egg until smooth.
Stir in mozzarella, pumpkin puree, almond flour, baking powder, pumpkin spice, sweetener, and salt. Mix well.
Lightly grease the waffle maker plates if needed.
Pour half the batter into the center and cook for 3–4 minutes, until golden brown.
Remove and repeat with remaining batter.
Let cool on a wire rack for 1–2 minutes to crisp up.
Serve warm with keto-friendly toppings like sugar-free syrup, whipped cream, or cream cheese drizzle.
