Preheat oven to 200 C and melt butter in a 9-inch skillet over low heat.
In a blender, place the milk, eggs, flour, sugar, vanilla extract, and salt, and blend just until smooth. You can also add all the ingredients in a big bowl and mix them with a mixer. The batter will be thin.
Once the butter is melted swirl it around the skillet to ensure all sides are coated
Working quickly, pour the batter into the skillet and place it directly in the oven. Bake for 15-20 minutes or until golden brown.
I like to top it with powder sugar or maple syrup and fresh berries. Or use toppings of your choice.
