Preheat your oven to 325°F. Liberally prepare a 12-cup Bundt pan with the nonstick method of your choice.
In the bowl of your stand mixer fitted with the whisk attachment, beat the butter for 1 minute on high speed.
Slowly add the granulated sugar. Cream together for an additional 5 minutes, until very pale yellow and fluffy.
Add the eggs 1 at a time, combining well after each addition and scraping down the sides and bottom of the bowl as needed.
Turn your mixer down to its lowest speed and slowly add the 3 cups of flour in 2 batches. Add the salt, baking powder and baking soda. Be careful not to overbeat.
Add the sour cream, vanilla extract, orange extract and orange zest. Scrape down the sides and bottom of the bowl and mix the batter until just combined. Turn off mixer and toss cranberries with remaining 2 tablespoons with flour then carefully fold cranberries into cake batter.
Bake for 1 hour and 15-25 minutes, or until a toothpick inserted into the center of the cake comes out mostly clean.
Let the cake cool in the pan on a wire rack for 10 minutes, then invert onto a serving plate. Let cool to room temperature and serve.
