Preheat the oven to 350°F, line a 9X5 pan with parchment paper and set aside.
Sift all the dry ingredients and set aside.
2¼ cups All-purpose flour, 1½ teaspoon Baking powder, ½ teaspoon Baking soda, ½ teaspoon Salt
Melt the butter and let it cool down slightly. Add the oil to the butter and mix
¼ cup Butter, 2 tablespoon Oil
Massage the orange zest into the sugar for a few minutes until the orange aroma is released.
¾ cup Sugar, 1 tablespoon Orange zest
Add the egg, vanilla, and melted butter to the sugar and whisk well.
1 Egg, 2 teaspoon Vanilla extract
Add the dry ingredients alternating with the orange juice; start and finish with the dry.
¾ cup Orange juice
Add the cranberries and raisins at the end, and mix as gently as possible. We do not want the cranberries to burst and bleed into the batter.
¾ cup Raisins, 1 cup Cranberries
Pour the batter into the prepared pan, and spread the streusel on top of the batter.
How To Make The Streusel
Using a fork, roughly mix the brown sugar, cinnamon, and flour. Do not mix fully; we want to have clusters of different sizes.
⅓ cup Brown sugar, ¼ cup All-purpose flour, 2 tablespoon Butter, 1 teaspoon Cinnamon
Spread the streusel all over the batter and bake for 55-60 Minutes. Until an insert comes out clean. Let the loaf cool in the pan for 15 minutes then lift the parchment paper and put the loaf on the cooling rack to cool down.
Make The Drizzle
Mix the powdered sugar and the orange juice. The mixture should have a pourable consistency but not be too runny.
