  • Vitamix Ascent
  • Hand mixer
  • Spatula
  • Bundt cake
  • Mixing bowl
  • measuring cups and spoons


  • 1 box ready to use spiced cake mix
  • 9 eggs
  • 1 teaspoon cinnamon
  • 1/2 cup caramel or cream soda
  • 1/2 cup milk
  • 1/2 cup corn oil
  • 1 teaspoon vanilla extract
  • 1 can evaporated milk
  • 1 can condensed milk
  • 2 cups sugar


  • Start by making the caramel. For that pour the sugar in a pot and cook until sugar is diluted and caramel color. Use a bundt cake pan and add oil spray, then pour the caramel to the pan. Distribute evenly. 
  • Make the flan or custard using the Vitamix® Ascent ™ 3500 blender. Add first the evaporated milk. Then the six eggs, vanilla extract, and condensed milk. Close the blender and when it clicks is safe to blend. Set on #5 turning the dial clockwise. Blend for 30 seconds. Pour the flan mix to the bundt cake pan and set aside.
  • Proceed to make the cake by adding the cake mix to a mixing bowl. Add the ground cinnamon, 3 eggs, milk, caramel or cream soda, corn oil and whisk until you get a nice batter.
  • Add the cake batter on top of the flan evenly. If the two blends together do not worry when the cooking process is started the two mixes will separate. 
  • Use a round tray big enough to fit the bundt cake pan. Add water and cook the cake on this water bath inside the oven for 45 minutes at 350 degrees Fahrenheit. When done let it rest inside the fridge preferably overnight.



  • Take the cake out to the pan when ready to display and eat.
  • Place cake in a nice serving dish.
  • Decorate with sugar Christmas motifs and enjoy.
