Prepare Your Oven and Pan: Preheat your oven to 350°F (175°C). Grease a 9×5-inch loaf pan with butter or cooking spray, then lightly dust with flour to prevent sticking.

Mix Dry Ingredients: In a large mixing bowl, whisk together flour, sugar, baking powder, salt, cinnamon, and baking soda until well combined.

Combine Wet Ingredients: In a separate bowl, mix the fresh orange juice, melted butter, beaten egg, and orange zest until smooth.

Make the Batter: Pour the wet ingredients into the dry ingredients and gently fold together until just combined. Don’t overmix – the batter should be slightly lumpy for the most tender bread

Add Cranberries and Nuts: Gently fold in the cranberries and walnuts (if using) until evenly distributed throughout the batter.

Bake the Bread: Pour the batter into your prepared loaf pan and spread evenly. Bake for 45-50 minutes, or until a toothpick inserted in the center comes out clean and the edges start pulling away from the pan.

Cool and Serve: Let the bread cool in the pan for 10 minutes, then turn out onto a wire rack. Cool for at least 15 minutes before slicing.
