Notes
Lemon Blueberry Zucchini Bread
Simply add 2 teaspoons of lemon zest to the wet ingredients. When mixing the dry ingredients omit the cinnamon, and continue to follow the recipe as written.The cinnamon / sugar topping may also be replaced by an easy Lemon Glaze.Lemon Glaze:Combine 2 cups powdered sugar with 2 tablespoons freshly squeezed lemon juice.Once the bread has cooled whisk together the powdered sugar and lemon juice. It should be thin enough to run off a spoon, but not too thick to drizzle on.Adjust glaze consistency by adding more powdered sugar (thicken) or lemon juice (thin).Pour on bread loaves and spread around to smooth. Allow the glaze to harden, about 20 minutes, before slicing.
