Mix milk and vinegar and set aside for 10 to 15 minutes.
Melt the butter and set aside to cool slightly.
Whisk together the flour, baking powder, sugar and in a large bowl.
In small mixing bowl, whisk together the buttermilk substitute, eggs, and vanilla extract.
Add the liquid to the dry mix and starting lightly mixing together till just wet and no large lumps but not smooth. The secret to thick, fluffy pancakes is not to over mix.
Slowly drizzle in the cooled butter and stir in as little as possible.
Put in the fridge for at least 10 minutes. This helps the butter to chill and bubbles to form in your batter for a fluffy cake.
Put a heavy bottom frying pan or a griddle on medium heat, allow to fully heat! (Cast Iron)
With a touch of melted butter spread on the pan, use a big ladle, to pour batter into a roughly 6” cake. Spread out gently into a round shape if needed with bottom of ladle.
Cook for about 4 minutes on one side. Turn them over when you see bubbles forming on the top of the pancake and the edges turn color. Do not lift until then.
Flip and cook on the other side until golden brown.
Enjoy with unsalted butter and natural maple syrup.
Notes
Being able to cook two or more on a griddle greatly reduces cooking time
