Add the sourdough starter, milk, egg, butter, vanilla and sugar to a bowl. Whisk well until just combined.
Now add the flour, baking powder and salt to the liquid ingredients and whisk until well combined and a batter forms.
This batter is ready to use straight away, but can be fermented overnight in the refrigerator if you want to.
Heat a large frying pan and add a little oil and butter to grease it.
Cook the pancakes to your desired size (use a mini soup ladle to scoop out the mixture). Let all the bubbles fully form on the surface before you flip them over. A lower heat is better as it lets the bubbles develop without burning the outside.
