A tender and moist sheet cake bursting with fresh blueberries and a tangy buttermilk crumb, perfect for any occasion and easy to make with simple ingredients.
Use softened, not melted butter for best texture. Fold blueberries gently to keep them mostly whole and prevent purple streaks. If using frozen blueberries, toss them lightly in flour before folding in to prevent sinking. Tent with foil if edges brown too quickly. The batter is thinner than typical cake batter but bakes into a moist crumb.
