What you'll need:
1 1/2 cups warm water (110 degrees F).
1 yeast packet (included).
1 whole egg.
3 egg whites.
1/4 cup melted butter, or vegetable oil.
1 package gluten free homemade wonderful bread mix.
Place warm water in a large mixing bowl. Sprinkle yeast over the warm water and set aside for 5 minutes. Oil a 9x5- or 8x4-inch loaf pan and set aside.
Add egg, egg whites, butter or oil, and bread mix to the yeast mixture. Using an electric mixer fitted with a paddle attachment, mix on low for 2 minutes. Turn the mixer off and scrape down the sides of the bowl with a rubber spatula. Continue to mix on medium speed for 6 minutes more. If preparing by hand, mix with a wooden spoon until the ingredients are very well combined.
Transfer the batter to the prepared baking pan. Lightly brush the top with oil or melted butter, or spray with nonstick cooking spray. Cover with plastic wrap and let rise in a very warm place until the batter reaches the top of the pan, about 45-60 minutes. While the bread rises, preheat the oven to 350 degrees F.
When the bread has risen, remove the plastic wrap and transfer the pan to the oven. Bake until the crust is a deep golden brown and the interior temperature reaches 210 degrees F, about 90 minutes.
If the crust begins to darken too much, cover foil.
Carefully remove the loaf from the pan and place it on a wire rack. Let cool completely before slicing.
Store in a cool, dry place to preserve freshness.
