Fluffy Pancakes

1 1/2 cup milk
4 Tbls white vinegar
2 cups all-purpose flour
4 Tbls white sugar
2 tsp baking powder
1 tsp baking soda
1 tsp salt
2 eggs
4 Tbls butter, melted
1 tsp vanilla

Combine milk with vinegar in a medium bowl and set aside for 5 minutes to "sour".

Combine flour, sugar, baking powder, baking soda, and salt in a large mixing bowl. Whisk eggs and butter into "soured" milk. Pour the flour mixture into the wet ingredients and whisk until lumps are gone. Add vanilla.

Heat a large skillet over medium heat, and coat with cooking spray. Pour 1/4 cupfuls of batter onto the skillet, and cook until bubbles appear on the surface. Flip with a spatula, and cook until browned on the other side.
