  • 1 1/4 cups brown-rice flour
  • 1/2 cup toasted walnuts, finely ground
  • 1/2 cup potato starch
  • 1/4 cup tapioca flour
  • 1 1/2 teaspoons baking powder
  • 1 teaspoon xanthan gum
  • 1/2 teaspoon salt
  • 2 large eggs, separated
  • 1/2 cup safflower oil
  • 1/2 cup packed light-brown sugar
  • 1 1/2 cups mashed overripe bananas (3 to 4)
  • 2 teaspoons pure vanilla extract


  1. Preheat oven to 350 degrees. Line a 12-cup muffin tin with baking cups. Whisk together brown-rice flour, ground walnuts, potato starch, tapioca flour, baking powder, xanthan gum, and salt. Whisk together yolks, oil, sugar, bananas, and vanilla. Fold flour mixture into banana mixture.

  2. Whisk whites until stiff peaks form. Working in 3 batches, fold whites into batter. Fill each baking cup with batter. Bake until light golden brown and a toothpick inserted into the centers comes out clean, 22 to 24 minutes. Let cool slightly. Turn out muffins onto a wire rack, and let cool completely.
