Preheat oven to 350F. Thaw your blueberries (or use fresh). Line muffin tin with paper or silicone cups or use a nonstick pan, and set aside. In a mixing bowl, whisk flour with baking powder, baking soda, salt, and sugar.
In a small food processor or blender, whiz banana with 1/4 cup plant-based milk until silky smooth. Stir into flour mixture, then add yogurt, applesauce, and remaining plant-based milk. Stir a few times, add blueberries and lemon zest, and stir gently, folding in blueberries, until just combined.
Spoon into muffin cups and bake 15-20 minutes or until muffins are golden, firm to the touch, and a toothpick inserted in the center comes out clean.
