In a measuring cup or small bowl, add the vinegar to the milk, stir, and set aside to slightly curdle to make acidified buttermilk.
1 cup milk, 1 tablespoon white distilled vinegar or lemon juice
In a large mixing bowl, whisk together the flour, baking powder, brown sugar, and salt.
1 cup all-purpose flour, 2 teaspoons baking powder, 2 tablespoons light brown sugar, ½ teaspoon salt
Add the egg, vanilla extract, and your acidified buttermilk mixture, and whisk until smooth, careful not to overbeat.
1 large egg, 1 teaspoon vanilla salt
Add butter to your griddle or frying pan and allow it to heat up on medium-high until the butter is melted.
3 tablespoons unsalted butter
For the thickest, most perfectly round pancakes, use silver dollar pancake molds. Pour batter into your molds or use about 2 tablespoons of batter to make freeform circles in the pan and cook over medium heat. When it's ready to flip, the batter on the uncooked side will start to form little air bubbles. Use a spatula to flip the pancakes, and allow them to cook on the other side for 2-3 minutes.
Repeat steps 5 and 6 until the pancake batter is used up, adding butter before each batch to keep your griddle greased. Keep them warm in the oven on "keep warm setting" (or 175°F) until ready to serve with maple syrup. Try serving them with these Soft Scrambled Eggs! ¼ cup maple syrup
