*The recipe works well with spelt flour, all purpose white flour, or all purpose gluten free flour.
1. Grease a 9x5 inch loaf pan and optionally line the bottom of the pan with parchment paper.
2. Preheat oven to 350° Fahrenheit (176° Celsius).
3. Stir flour, sugar, baking powder, salt, and baking soda in a large bowl until evenly incorporated.
4. Stir in the orange juice, zest, oil, egg or flax egg, and pure vanilla extract until just evenly mixed. Do not overbeat the batter.
5. Spread into the prepared pan, then bake on the center rack of the oven for 40 minutes or until lightly golden and cooked in the center. A toothpick inserted into the middle of the orange bread should come out mostly clean.
6. Let cool fully before going around the sides of the pan with a knife and popping the loaf onto a serving plate. (Alternatively, cut slices directly from the pan.)
7. Store leftovers loosely covered on the counter overnight. Both the taste and texture taste even better the next day!
8. Any leftovers after one day should be covered and refrigerated or frozen for optimal freshness.
