- 2 cups Idahoan® Boxed Original Mashed Potatoes, dry
- 1 stick unsalted butter
- 8 ounces Coca-Cola® (or Guinness® for an adult cake)
- 1/2 cup unsweetened cocoa powder
- 1 3/4 cups superfine sugar
- 1/2 cup sour cream
- 2 medium eggs
- 1 tablespoon vanilla
- 2 1/2 teaspoons baking soda
- Frosting:
- 2 (8 ounce) packages cream cheese
- 1/3 cup heavy cream
- 3/4 cup powdered sugar
- Preheat oven to 350 degrees F. Coat the sides and bottom of spring form pan with nonstick cooking spray.
- Melt stick of butter in a large, wide sauce pan.
- Add cola, cocoa powder and superfine sugar and whisk until smooth. Remove from heat.
- Whisk sour cream, eggs and vanilla thoroughly until almost a batter-like consistency and add slowly into the slightly cooled butter mixture.
- Add dry Original Mashed Potato flakes and baking soda. Stir thoroughly. The batter will have a slightly grainy appearance but don't be concerned.
- 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).
- Cool and remove from spring form pan. Note: This is a very dark and dense cake.
- Frosting: 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.
- Frost just the top of the cake once it's unmolded and serve chilled. This cake is even better the next day!
