If you can find them, wild Maine blueberries add a refreshing tartness to the pancakes, and so do huckleberries.More Brunch Recipes
In a medium bowl, whisk together the flour, sugar, baking powder and baking soda. In another bowl, whisk the buttermilk with the eggs and melted butter. Add the buttermilk mixture to the dry ingredients and stir just until incorporated. Fold in the blueberries; be careful not to crush them or the batter will turn purple.
Heat a cast-iron griddle or skillet over moderately high heat and brush lightly with butter. Spoon rounded 1/4 cupfuls of batter onto the griddle, spreading each out slightly. Cook the pancakes until the bottoms are browned, the tops are slightly set and small bubbles appear, about 3 minutes. Flip the pancakes and cook until golden, about 1 minute. Serve the pancakes hot off the griddle with butter and maple syrup. Continue making pancakes with the remaining batter.
