Irish Chocolate Potato Cake

Submitted by Marcia Van Camp

Inspired by This is a really cool website and has some other fun facts about the recipe.

You read the title correctly, there are really potatoes in this chocolate cake and it's a really, REALLY good cake, so take a chance and try it out!

No pictures for now because we ate it too fast!

  • 1/2 lb unsalted butter
  • 2 1/3 cups / 1 pound granulated sugar
  • 4 large eggs
  • 9 rounded tablespoons grated chocolate (I used about 1 ½ bars of Ghirardelli’s milk chocolate baking bars)
  • 3 tablespoons cocoa (I used dark chocolate)
  • 1 cup cooked and mashed potato (cooled, do not add hot or warm)
  • 2 1/2 cups flour  
  • 1/2 teaspoon cinnamon
  • 2 rounded teaspoons baking powder
  • 1/2 teaspoon salt
  • 2/3 cup milk (I used whole milk)

Bundt pan Directions: (I didn’t use this method)
For preparing the pan you'll bake in:
  • 1 1/2 tablespoons flour
  • 1 1/2 tablespoons cocoa
First prepare your cake pan. A tube pan like a Bundt pan works best for this recipe: but a springform cake pan works fine too.

If using a tube pan or Bundt pan, butter it well inside, paying particular attention to any flutings or crevices in the pan. Then mix the flour and cocoa together and use this mixture to flour the inside of the pan.

Springform pan Directions:
If using a springform pan, butter it too: then line it with a circle of buttered baking parchment for the bottom and a strip of buttered baking parchment for the sides.

This is the method I used because I couldn’t find my Bundt pan.  It was yummy, but I think the Bundt has a better shape for presentation.

Here is a video which might help:

Cake Directions:
·        Preheat the oven to 350° F. Then prepare the cake batter:

·         Grate the chocolate on a fine grater, or pulse in a food processor, or crush with a mortar and pestle, until reduced to small granules. The food processor is by far the easiest and fastest way: the grater and mortar-and-pestle are more labor intensive, but produce a slightly finer result. (I did it by hand and it took a while and because it was milk chocolate it was messy.  Next time I think I will try the food processor).

·         When this is done, sift the flour once by itself. Then sift it a second time with the cinnamon, baking powder and salt.

·         Cream the butter with the sugar until light and fluffy. (Mine wasn’t light and fluffy but it looked mixed!)

·         Separate the eggs. Add the yolks, one at a time, to the creamed mixture, beating well after each one.

·         Stir in the grated chocolate, ground almonds (optional) and cocoa. Add the potato and stir again.

·         Add the flour alternately with the milk, beating gently until smooth after each addition.

·         When this process is complete, whip the egg whites until stiff but not dry. Fold the whipped egg whites carefully into the cake mixture.

·         Spoon into the prepared springform pan or Bundt pan / tube pan: tap gently once on the counter to settle. Bake for 1 3/4 hours. Test for doneness with a toothpick or skewer at the end of this time: bake for another 15 minutes if needed.

·         Remove from the oven and allow to rest in the pan for at least twenty minutes before removing from the pan: then cool on a rack.

·         To finish, you could dust with confectioners' sugar but I chose to drizzle some chocolate over it.
I used the fudge sauce from this recipe, and I only needed about ½ but I put the rest in the freezer and it’s been nice to have it ready to go for other desserts.

1.       The original recipe has you sieve the potatoes, but I didn’t really know how and I didn’t have time to do it. The end result was that I had tiny, very tiny lumps in my cake, but I actually liked them because they made it seem like there were soft little nuts in there.  I am sure the cake is awesome with sieving BUT it’s not a deal breaker.

2.       The original recipe calls for 5 rounded Tbls ground almonds but I excluded them in case of nut allergies.  After tasting the cake, I think that almonds would be really good and I want to try them next time.
