This recipe originally came from one of our favorite Food Network stars, Nigella Lawson. A little alteration here and there (like including Idahoan®’s Original Mashed Potatoes) to this wonderfully rich cake made with Coca-Cola and a new favorite was created!

Idahoan® Coca-Cola® Cake
Serves: 12
  • 2 cups Idahoan® Original Mashed Potatoes, dry (from the 13.75 oz or 26.2 oz box—NOT from the 2 oz pouch)
  • 10 Tbsp unsalted butter (1 cube + 2 Tbsp)
  • 8 oz Coca-Cola® (or Guinness for an adult cake)
  • ½ cup unsweetened cocoa powder
  • 1¾ cups superfine sugar
  • ½ cup sour cream
  • 2 medium eggs
  • 1 Tbsp vanilla
  • 2½ tsp baking soda
  • 2 - 8 oz packages cream cheese
  • ⅓ cup heavy cream
  • ¾ cup powdered sugar
  1. Preheat oven to 350°F. Coat the sides and bottom of springform pan with nonstick cooking spray.
  2. Melt cube of butter in a large, wide sauce pan.
  3. Add cola (or beer), cocoa powder and superfine sugar and whisk until smooth. Remove from heat.
  4. Whisk sour cream, eggs and vanilla thoroughly until almost a batter-like consistency and add slowly into the slightly cooled butter mixture.
  5. Add dry Original potato flakes and baking soda. Stir thoroughly. The batter will have a slightly grainy appearance but don’t be concerned.
  6. Pour into spring form pan and bake for 45 minutes to an hour. Test center of cake with a wooden toothpick (cake is done when the toothpick comes out clean).
  7. Cool and remove from springform pan. Note: This is a very dark and dense cake.
Frosting: Ice cake once it is thoroughly cooled.
  1. The cream cheese should be at room temperature. Add cream and powdered sugar and mix in a food processor or with a large whisk. Adjust powdered sugar and cream to ensure a nicely thick frosting that is still spreadable.
  2. Frost just the top of the cake once it’s “unmolded” and serve chilled. This cake is even better the next day!
