Preheat Oven:
Preheat the oven to 350°F (175°C). Grease and flour a 10ā12 cup bundt pan, ensuring all crevices are coated to prevent sticking.
Mix Dry Ingredients:
In a medium bowl, whisk together the flour, baking powder, baking soda, and salt. Set aside.
Cream Butter & Sugar:
In a large mixing bowl, beat the softened butter and granulated sugar together until light and fluffy, about 3ā4 minutes.
Add Eggs & Flavorings:
Add the eggs one at a time, mixing well after each addition. Mix in orange zest, orange juice, and vanilla extract.
Add Sour Cream & Dry Ingredients:
Add the sour cream and mix until just incorporated. Gradually add the dry ingredients in batches, mixing until just combined.
Fold in Cranberries:
Toss the cranberries with 1 tablespoon of flour (this prevents them from sinking) and gently fold them into the batter.
Bake:
Pour the batter evenly into the prepared bundt pan. Bake for 50ā60 minutes, or until a toothpick inserted in the center comes out clean.
Cool:
Let the cake cool in the pan for 15ā20 minutes, then invert it onto a wire rack to cool completely before glazing.
