Preheat your oven to 350°F (175°C) and prepare a loaf pan.
In a medium bowl, whisk together the flour, baking powder, baking soda, and salt.
In another bowl, combine the melted butter and sugar until well blended.
Add the egg, orange juice, and zest to the butter mixture, and mix until smooth.
Gradually fold the dry ingredients into the wet ingredients until just combined.
Fold in the chopped cranberries gently until evenly distributed.
Pour the batter into the prepared loaf pan and smooth the top.
Bake in the preheated oven for about 50-60 minutes, or until a toothpick comes out clean.
Remove from the oven and allow to cool in the pan for 10 minutes before transferring to a wire rack.
Slice and serve the cooled cranberry orange bread as desired.
