  • 1¼ teaspoons baking powder
  • ¾ teaspoon salt
  • ½ teaspoon xanthan gum

In large mixing bowl, whisk together white rice flour, sugar, potato starch, baking powder, salt and xanthan gum. Add butter, milk, eggs and vanilla. Using a handheld mixer, mix until a thick batter forms, about 1 minute. Spread batter evenly into prepared pan.
