Banana Nut Muffins

01Method

1. 1

   Heat the oven to 350 °F (175 °C) and line a 12-cup muffin tin with paper liners.

2. 2

   Combine the flour, baking powder, baking soda, and salt in a large bowl and stir to mix.

3. 3

   In a separate bowl, whisk the egg whites until foamy, then mix in the bananas, sugar, oil, and lemon zest. Pour the wet mixture into the dry ingredients and stir just until the batter comes together, then fold in the walnuts. Spoon the batter into the lined muffin cups, filling each about two-thirds of the way.

4. 4

   Bake until the tops turn lightly golden, 20 to 25 minutes. Transfer the muffins to a wire rack and let them cool.
