A moist, tender loaf studded with blueberries and flecks of grated zucchini. Easy one-bowl method that yields a flavorful quick bread perfect for breakfast, snacks, or sharing.
Preheat oven to 350°F (175°C). Grease and flour a 9x5-inch loaf pan or line with parchment.
Whisk together flour, baking soda, baking powder, salt, and cinnamon in a medium bowl.
In a large bowl, whisk melted butter with granulated and brown sugar. Add eggs, vanilla, and yogurt, mixing until smooth.
Stir grated zucchini into wet mixture, then add dry ingredients in two additions, folding gently until just combined.
Toss blueberries with a tablespoon of flour, fold into the batter, pour into pan, and bake 50–60 minutes until a toothpick comes out with a few crumbs.
Cool in the pan 10–15 minutes, then remove to a rack to cool completely before slicing.
Notes
If using frozen blueberries, fold them in frozen to prevent bleeding.
Grate zucchini finely so it blends into the batter and keeps the crumb tender.
To prevent a domed or cracked top from over-browning, tent with foil halfway through baking if needed.
