Ingredients
1 1/2 cups all-purpose flour (spooned and leveled)
1/4 cup ground flaxseed
2 tablespoons sugar
1 1/4 teaspoons baking powder
1/4 teaspoon baking soda
1/4 teaspoon fine salt
1 1/2 cups buttermilk
1 large egg, lightly beaten
1 tablespoon unsalted butter, melted, plus more for skillet and serving
1 cup fresh or frozen blueberries
Maple syrup, for serving
Preparation
In a large bowl, whisk together flour, flaxseed, sugar, baking powder, baking soda, and salt. Add buttermilk, egg, and butter and whisk until just moistened (batter should have some lumps; do not overmix). Fold in blueberries.
Lightly coat a large nonstick skillet or griddle with butter and heat over medium-high. In batches, drop batter by 1/4 cupfuls into skillet. Cook until bubbles appear on top and a few have burst, 2 to 5 minutes. Flip pancakes and cook until golden brown, 2 to 5 minutes. Repeat with more butter and remaining batter (makes about 12), wiping skillet clean between batches and lowering heat if necessary. Serve with butter and syrup.
