Blueberry Pancakes

Preheat oven to 200°F. Combine flour, sugar, baking powder, baking soda, and salt in a large bowl; make a well in center of mixture. Stir together buttermilk, oil, and egg; add to flour mixture, stirring until smooth.

Place 1 tablespoon of the butter in a large nonstick skillet over medium-high, and heat just until melted and beginning to foam. Reduce heat to medium. Using about half the batter, pour 1/4 cup portions into hot skillet, and sprinkle top of each with some of the blueberries. Cook until golden brown on bottom and bubbles begin to form on top, 2 to 3 minutes. Flip and cook until golden brown on bottom, 1 to 2 minutes. Place cooked pancakes on a baking sheet, and keep warm in preheated oven. 

Repeat with remaining butter and batter. Serve pancakes with maple syrup and softened butter.
