  • Bundt pan


For cake batter:

  • 1 15.25 ounce box chocolate cake mix
  • 1/4 teaspoon kosher salt
  • zest of 2 oranges
  • 1/2 cup buttermilk
  • 1/2 cup fresh orange juice
  • 1 cup vegetable or canola oil
  • 4 large eggs
  • 1 teaspoon vanilla extract
  • 1/2 cup sour cream

For chocolate ganache:

  • 4 ounces semi-sweet chocolate, chopped
  • zest of 1 orange
  • 1/2 cup heavy cream


  • Preheat oven to 350 degrees. Grease a bundt pan well. Set aside.
  • In a large bowl, combine cake mix, kosher salt and orange zest from 2 oranges. Set aside.
  • In another bowl, whisk together buttermilk, orange juice, oil, eggs, vanilla and sour cream. Pour into the dry mixture and fold until it just comes together. Pour into prepared bundt pan.
  • Bake for 35 to 40 minutes, until a toothpick comes out clean. Remove from oven and let cool for 5 minutes. Place a cooling rack on top of the cake and gently flip to release the cake from the bundt pan. Allow to fully cool.
  • Once cake is cool, make the ganache. Place chopped chocolate and orange zest into a bowl. Set aside. Add heavy cream to a small saucepan or microwave safe bowl. Bring to a simmer then remove from heat. Pour hot heavy cream over the chocolate mixture and stir until all the chocolate is melted. Pour over the cooled cake.
