Preheat your oven to 350°F (175°C). Grease the loaf pan or line it with parchment paper.
In a mixing bowl, combine the flour, sugar, baking powder, baking soda, and salt. Whisk until well mixed.
In a separate bowl, mix the orange juice, vegetable oil, egg, and orange zest until fully combined.
Pour the wet ingredients into the dry ingredients. Stir gently with a rubber spatula until just combined. Do not overmix.
Fold in the halved cranberries gently, ensuring they are evenly distributed in the batter.
Pour the batter into the prepared loaf pan and smooth the top.
Bake in the preheated oven for 55-60 minutes, or until a toothpick inserted in the center comes out clean.
Once baked, remove the loaf from the oven and let it cool in the pan for about 10 minutes before transferring it to a wire rack to cool completely.
Slice and serve. Enjoy your cranberry bread!
