Preheat your oven to 375°F (190°C). Line a muffin pan with paper liners or lightly grease it. Scoop out two tablespoons from the 1 3/4 cups of flour and toss with the blueberries - this helps keep them from sinking. Set aside.
In a large bowl, whisk together the remaining flour, baking powder, baking soda, and salt.
In another bowl, mix the yogurt, apple sauce, oil, eggs, sugar, and vanilla until smooth.
Add the wet ingredients to the dry and stir gently until just combined.
Fold in the floured blueberries and lemon zest.
Divide the batter evenly among the muffin cups. Fill each cup almost to the top — this gives you 9 tall, domed muffins rather than 12 flat ones.
Bake for 18–25 minutes, or until a toothpick comes out clean and the tops are lightly golden.
Let cool and enjoy… or wrap them up and stash a couple in your travel bag.
