I was actually surprised when these muffins turned out as good as they did! And in only one bowl, too 🙂
I used the ratio for muffins and quick breads from Ruhlman's book Ratio. This ratio is 2 parts flour: 2 parts liquid: 1 part egg: 1 part sugar: 1 part fat. Then added the basic salt and baking powder, and a couple handfuls of blueberries (so much cheaper while they're in season!), and voila!!
