Ingredients
1 1/2 cups unbleached all-purpose flour
1/2 cup buckwheat flour
2 teaspoons baking powder
1/2 teaspoon baking soda
2 tablespoons sugar
1/2 teaspoon kosher salt
3 large eggs, room temperature
2 tablespoons unsalted butter, melted, plus more, room temperature, for serving
1 1/2 cups buttermilk
1 teaspoon pure vanilla extract
Safflower oil, for griddling
Pure maple syrup, for serving
Preparation
In a large bowl, whisk together flours, baking powder, baking soda, sugar, and salt. Make a well in center; add eggs, butter, buttermilk, and vanilla. Whisk until just combined but still lumpy (do not overmix). Let stand 15 minutes.
Preheat a large cast-iron or nonstick skillet or griddle over medium. Drizzle with 1 teaspoon oil; wipe with a paper towel to leave a thin film. Pour 1/4 cup batter per pancake onto skillet, leaving 1 inch between each. Cook until bubbly on top and golden on bottom, and beginning to lift from skillet along bottom edges, 2 to 3 minutes. Flip and cook on other side until golden on bottom, puffed, and just cooked through, about 1 minute more. Transfer to a baking sheet lined with a wire rack; keep warm in oven on low heat until ready to serve. Serve with butter and syrup.
