Start by preheating your waffle maker according to the manufacturer’s instructions. Lightly grease it with butter, oil, or nonstick spray to prevent sticking.

In a medium bowl, whisk together the eggs, melted butter, almond milk, and vanilla extract. Mix until the ingredients are fully combined and smooth.

Add the almond flour, baking powder, salt, and sweetener (if using) to the bowl. Stir the mixture until a smooth batter forms with no large lumps.

Pour the batter into the preheated waffle maker, spreading it evenly. Close the lid and cook for about 3–5 minutes, or until the waffles are golden and slightly crisp.

Carefully remove the waffles and serve immediately. Top with butter, sugar-free syrup, fresh berries, or whipped cream for a delicious keto-friendly breakfast.
