In a large mixing bowl, add ingredients as listed and only half the grated lemon zest.
Grease muffin tins.
Dust the greased tins with sugar.
Pour the batter evenly into muffin tins. If desired, mix the remaining lemon zest with our simple streusel topping and sprinkle evenly on the top, or use a mixture of the zest and sugar.
Bake for 25-35 minutes or until the bread loosens evenly from the sides and a toothpick inserted in the center of the bread comes out clean.
