Instructions
Preparation Steps
Preheat oven to 350°F. Grease a 9x5-inch loaf pan with butter and line with a parchment sling.
Whisk together 2.0 cups flour, baking soda, baking powder, salt, and cinnamon in a medium bowl.
In a small bowl, toss blueberries with 1.0 tablespoon flour to lightly coat; set aside.
In a large bowl, whisk melted butter with granulated sugar and brown sugar until glossy. Whisk in eggs and vanilla until smooth. Add mashed bananas and yogurt; whisk to combine.
Add dry ingredients to wet and fold gently just until a few streaks of flour remain.
Fold in floured blueberries and lemon zest until evenly distributed; do not overmix.
Scrape batter into prepared pan and smooth the top. Bake 55 to 65 minutes, until a toothpick comes out with a few moist crumbs (or internal temp about 200°F). Tent with foil after 40 minutes if browning quickly.
Cool in pan 15 minutes, then lift out to a wire rack to cool completely before slicing.
Notes
Use frozen blueberries straight from the freezer to minimize bleeding. Store tightly wrapped at room temperature for 2 days or refrigerate up to 5 days. For muffins, bake at 350°F for 20 to 24 minutes.
