We're sure you doubled all the ingredients and baked in a 8 1/2" X 4 1/2" pan. Sometimes doubling the recipe will lead to an over-yeasted bread, so it might be good to check the recipe by making just one loaf. If you want to double it in the future, then use 1.5X the yeast to see if doubling the GF bread is possible. Happy GF Baking! Irene@KAF
