Buttermilk Pancakes
 

2 cups all-purpose flour
2 teaspoons baking powder
2 teaspoons sugar
1/2 teaspoon salt
2 cups buttermilk, plus more for thinning
1 large egg, beaten
3/4 teaspoon vanilla extract
1 tablespoon vegetable oil, plus about 1/4 cup for the pan

Into a large bowl, sift together the flour, baking powder, sugar, and salt. Add the buttermilk, the egg, and 1 tablespoon of oil, and stir just until blended, being careful not to over mix. (Lumps are okay.) Let the batter stand, covered, in the refrigerator, for at least 1 hour, and up to 8 hours. If necessary, thin with extra buttermilk after resting.
Preheat a large, heavy skillet or griddle over medium-high heat. Add enough oil to lightly grease and leave a film on the bottom of the pan.

Working in batches, ladle the batter about 1/2 cup at a time into the pan. Cook until golden brown and bubbles start to form on the top, about 2 minutes per side. Transfer to a platter and cover to keep warm.
