Is it a bread? Is it a cake? The beauty of this walnut-topped blueberry loaf is its versatility, its ability to be whichever you want it to be. It’s not too sugary, so it tastes great toasted, blueberries bursting, and slathered with butter for breakfast. But its moist, dense texture and sweet topping also pair well with coffee or tea. The best way to decide? Bake it yourself and try it both ways!
