For the Cake:

• In a large bowl, combine the sugar and orange zest. Using your fingers, massage the zest into the sugar. Let rest for 15 minutes.
  3 cups sugar, Zest of 2 oranges
• Preheat the oven to 325°F. Spray a 12-cup bundt cake pan with baking spray with flour. Alternatively, spray the pan with nonstick cooking spray and then coat the inside thoroughly with flour, shaking out and discarding any excess flour.
• In the bowl of a stand mixer fitted with the paddle attachment beat the butter on medium speed for 2 minutes, or until pale in color.
  1 cup butter, room temperature
• Add the sugar and orange zest mixture to the bowl and beat on medium speed for 3 minutes, scraping the bottom and sides with a rubber spatula as needed.
• Add the eggs, one at a time, beating between each addiiton just until you can no longer see the egg yolk.
  6 eggs, room temperature
• Add the flour and heavy cream, alternatively, beginning and ending with the flour.
  3 cups flour, 1 cup heavy whipping cream
• Add the vanilla and mix just until combined, scraping the bottom and sides with the rubber spatula as needed.
  1 tablespoon vanilla
• Carefully transfer the batter to the prepared bundt pan and bake in the preheated oven for 1 hour 20 minutes or until a toothpick inserted in the center comes out mostly clean with a few moist crumbs.
• Remove the cake from the oven and allow it to cool for 25 minutes before carefully inverting the cake onto your serving platter.
• Combine the orange juice and sugar in a small bowl. Brush the entire outside of the cake with the orange juice glaze. Allow the cake to cool completely.
  ¼ cup orange juice, ¼ cup sugar
• Once the cake is cool, juice ½ of an orange into a small bowl. Add the vanilla and powdered sugar, stirring well with a whisk until smooth. If the powdered sugar glaze is too thing, additional powdered sugar by the ¼ cupful, until desired consistency is reached. Sprinkle the top with orange zest.
  Juice from ½ of an orange, 1 cup powdered sugar, 1 teaspoon vanilla extract, Orange zest for garnish
