Combine almond flour, baking powder, and salt in a large bowl.
In another bowl, whisk together eggs, melted butter, erythritol, and vanilla extract.
Pour the wet ingredients into the dry ingredients and knead into a dough.
Divide the dough into 6 portions and shape them into rounds.
Place on a baking tray and bake in a preheated oven at 180°C (356°F) for 18–20 minutes.
Let cool. Keto scones are ready to serve.
