Chocolate Beet Cake

What do you do when you end up with too many beets in your CSA?  Make chocolate cake, of course!  This recipe from Nigel Slater has been on my "to bake" list for a while, and since the beets have been coming in a steady stream all winter, I really had no excuse.  I'll warn you up front that this cake involves a lot of work: there's cooking the beets, pureeing the beets, melting the chocolate in a double boiler, whipping the egg whites, sifting the cocoa powder and flour.  Whew!  This cake definitely creates a lot of dishes.  That said, if you've got an afternoon to spare, the final product is both beautiful and delicious.  The cake is pink going into the oven, but it comes out a lovely mahogany color.  It's super moist, and the beets lend a subtle earthy flavor.  The cake makes a great dessert, and the beets make me feel it's a semi-legitimate choice for breakfast - it's definitely fantastic alongside a cup of coffee.


Chocolate Beet Cake (adapted from Tender: A Cook and His Vegetable Patch)
Makes one 9-inch round cake, serving at least 8

8 ounces trimmed beets (about three medium-small)
7 ounces dark chocolate, chopped
1/4 cup strong brewed coffee
3/4 cup plus 2 T unsalted butter, cut into small pieces
5 eggs, separated
Scant 1 cup sugar
1 cup plus 2 T all purpose flour
3 T cocoa powder
1 heaping tsp baking powder
1/4 tsp salt

1. Grease a 9-inch springform pan.  Preheat the oven to 350 degrees.
2. Bring a large pot of water to a boil, and cook the beets (whole and unpeeled), until tender - about 30 to 40 minutes.  Drain, let cool under running water, and then slip off the skins.  Slice off the stem and root, and then puree until very smooth.  Set aside.
3. Set up a double boiler, and place the chocolate in the top over simmering water.  Stir occasionally.  When the chocolate looks almost melted, add the coffee and stir to combine.  Add the butter, and stir to combine.  Let the butter soften, stirring occasionally.  When the butter is almost all melted remove from the heat and allow the butter to continue to melt from the heat of the chocolate.  Stir to combine, and then let cool slightly.
4. Place the yolks in a large bowl and stir to break them up.  Place the whites in a separate bowl.
5. Add the chocolate-butter mixture to the egg yolks and stir quickly to combine.  Fold in the pureed beets.
6. Beat the egg whites with an electric mixer until foamy.  Add the sugar and beat until stiff peaks form.  Add the whites to the chocolate mixture and gently fold them in.  Sift the flour, cocoa powder, baking powder, and salt over the batter.  Gently fold in, being careful not to deflate the batter too much, but also making sure the flour is fully incorporated (a delicate balance!)
7. Scrape the batter into the prepared pan.  Place in the oven, and immediately decrease the temperature to 325 degrees.  Bake 45-50 minutes, until a tester comes out slightly moist.  Set aside to cool, and then remove from pan.

    1. I think you'd be able to tell that there was some sort of unusual ingredient in the cake, but I don't know if you'd be able to pick out that it was beets. :)

  7. you read my brain! I'm absolutely in love with Nigel Slater's recipes, and this is one i also had bookmarked to try. It looks so beautiful! I've been putting it off too, but you're right: you can hardly justify doing that right now with all the beets around. Nice work, sara.

  8. I always think it's so cool to make chocolate cake with beets! You can typically get away without sifting. I don't think I have ever sifted dry ingredients, and I've never had a problem.

    1. Thanks! It was definitely a fun (and delicious) experiment!

      In this case, I think the sifting is important because the dry ingredients aren't mixed together before adding to the batter, and then after adding, the batter should be folded as gently as possible - I think if you just dumped everything into the batter, you'd need to fold more to get everything properly incorporated with no lumps of cocoa, etc. But, if you don't want to sift, you could just whisk the dry ingredients together in a small bowl before adding to the batter (I didn't want to add another dish to wash!)
