A moist and tender blueberry coffee cake with a crunchy cinnamon brown sugar streusel topping, perfect for breakfast or brunch. This easy recipe uses simple pantry staples and fresh blueberries for a bright, flavorful treat.
Do not overmix the batter to keep the cake tender. Use fresh, firm blueberries to avoid soggy batter; if using frozen, fold them in frozen. Cold butter is essential for a crunchy streusel topping. Room temperature eggs and sour cream help create moist texture. Bake immediately after assembling batter to prevent blueberries from sinking. Tent with foil if topping browns too fast.
