Dry Pancake Mix
- 10 ounces (about 2 cups) all purpose flour
- 1 teaspoon baking powder
- 1/2 teaspoon baking soda
- 1 teaspoon kosher salt
- 1 tablespoon sugar
Wet Pancake Mix
- 2 large eggs, separated
- 1 1/2 cups (about 12 ounces) buttermilk
- 1 cup (about 8 ounces) sour cream (see note)
- 4 tablespoons unsalted butter, melted
For the Dry Pancake Mix: Combine flour, baking powder, baking soda, salt, and sugar in a medium bowl and whisk until homogenous. Transfer to an airtight container. The mix will stay good for 3 months. (See note.)
For each Batch of Pancakes: Place one batch of dry mix in a large bowl. In a medium clean bowl, whisk the egg whites until stiff peaks form. In a large bowl, whisk the egg yolks, buttermilk, and sour cream until homogenous. Slowly drizzle in the melted butter while whisking. Carefully fold in the egg whites with a rubber spatula until just combined. Pour the mixture over the dry mix and fold until just combined (there should still be plenty of lumps).
Heat a large heavy-bottomed nonstick skillet over medium heat for 5 minutes (or use an electric griddle). Add a small amount of butter or oil to the griddle and spread with a paper towel until no visible butter or oil remains. Use a 1/4-cup dry measure to place 4 pancakes in the skillet and cook until bubbles start to appear on top and the bottoms are golden brown, about 2 minutes. Carefully flip the pancakes and cook on the second side until golden brown and completely set, about 2 minutes longer. Serve the pancakes immediately, or keep warm on a wire rack set on a rimmed baking sheet in a warm oven while you cook the remaining 3 batches.
Pancake dry mix can be scaled up as many times as you'd like. Each batch of pancakes takes 11 ounces of dry mix to make (about 2 cups plus 2 tablespoons).
The sour cream can be replaced with more buttermilk.
