Tuesday 4 December 2007


I know December is going to be a busy month, so I'm going to have to multi-task. My December Recipe Mission will also be my contribution to a Christmas Party I'm going to at G's house for her husband's 40th birthday. I'm thinking Greenspan's Black and White Chocolate Cake is going to be the special cake for this celebration. Knowing what a chocolate lover G is, I hope this cake meets my expectations as a show-stopper--and her expectations for chocolate!

I can't see anything that can go wrong with any of the components and I expect the cake to turn out a success. I hope all goes well...

I'm also going to be baking a whole whack of cookies for my Christmas Cookie Boxes, so I'll be on the lookout for intriguing recipes to include. This year, I'm thinking of including my usual Green Tea Christmas Trees (with a tweak to the recipe--to not be so bitter!) and my Butter Cookies (but kicked up with real vanilla beans!) and Chocolate Chip Oatmeal Cookies. Perhaps I'll add the Cocoa Nib & Pecan Cookies in there too. Greenspan's Korova cookies caught my eye, and I may experiment with those too.

I'm anxiously anticipating undergoing Lasik Eye Surgery on the 6th, so I have no idea if I'll be able to see well enough to post in the coming couple of weeks. Or perhaps I'll be too busy putting eye drops in my eyes around the clock initially...we'll see (har har, I hope!)

So here's the Greenspan recipe I'll be testing out on my friends:

Black-And-White Chocolate Cake
(from Dorie Greenspan's Baking: From My Home to Yours)
For the Cake:
2 cups cake flour
2 t baking powder
1/8 t baking soda
1/4 t salt
1 1/4 sticks (10 T) unsalted butter, room temp.
1 cup sugar
3 large eggs
1 large egg yolk
1 t pure vanilla extract (I'm going to substitute vanilla beans from my huge stash!)
3/4 cup buttermilk

For the Dark Chocolate Cream:
2 cups whole milk
4 large egg yolks
6 T sugar
3 T cornstarch, sifted
1/4 t salt
7 oz bittersweet chocolate, melted
2 1/2 T unsalted butter, cut into 5 pieces, at room temp

For the White Chocolate Whipped Cream:
6 oz premium quality white chocolate (such as Valrhona Ivoire or Guittard), finely chopped
1 1/2 cups heavy cream

Chocolate shavings or curls for decoration (optional)

Getting Ready: Center a rack in the oven and preheat the oven to 350degrees F. Butter two 9 x 2 inch round cake pans, dust insides with flour, tap out the excess and line the bottoms of the pans with parchment or wax paper. Put the pans on a baking sheet.

To Make the Cake: Sift together the cake flour, baking powder, baking soda and salt.

Working with a stand mixer, preferably fitted with a paddle attachment, or with a hand mixer in a large bowl, beat the butter on medium speed until soft and creamy. Add the sugar and beat for another 3 minutes. Add the eggs one by one, and then the yolk, beating for 1 minute after each addition. Beat in the vanilla; don't be concerned if the mixture looks curdled. Reduce the mixer speed to low and add the dry ingredients alternately with the buttermilk, adding the dry ingredients in 3 additions and the milk in 2 (begin and end with the dry ingredients); scrape down the sides of the bowl as needed and mix only until the ingredients disappear into the batter. Divide the batter evenly between the two pans and smooth the tops with a rubber spatula.

Bake for 28 to 30 minutes, rotating the pans at the midway point. When fully baked, the cakes will be golden and springy to the touch and a thin knife inserted into the centers will come out clean. Transfer the cakes to a rack and cool for about 5 minutes, then unmold, remove the paper and invert to cool to room temperature right side up on the rack.

To Make the Dark Chocolate Cream:
Bring the milk to a boil.

Meanwhile, in a large heavy-bottomed saucepan, whisk the egg yolks with the sugar, cornstarch and salt until thick and well blended. Whisking without stopping, drizzle in about 1/4 cup of the hot milk--this will temper, or warm, the yolks so they won't curdle--then, still whisking, add the remainder of the milk in a steady stream. Put the pan over medium heat and, whisking vigorously, constantly and thoroughly (make sure to get into the edges of the pan), bring the mixture to a boil. Keep at a boil, still whisking, for 1 to 2 minutes. Remove the pan from the heat.

Whisk in the melted chocolate, and let stand for 5 minutes. Then whisk in the pieces of butter, stirring until they are fully incorporated and the chocolate cream is smooth and silky. Press a piece of plastic wrap against the surface of the cream to create an airtight seal and refrigerate the cream until chilled, or for up to 3 days. Or, if you want to cool the cream quickly, put the bowl with the cream into a larger bowl filled with ice cubes and cold water and stir the cream occasionally until it is thoroughly chilled, about 20 minutes.

To Make the White Chocolate Whipped Cream:
Put the white chocolate in a heatproof bowl and put the bowl over a saucepan of gently simmering water. Stir frequently to melt the chocolate evenly. Meanwhile, bring 1/2 cup of the heavy cream to a boil.

When the white chocolate is melted, remove the bowl from the pan. Pour the hot cream into the melted chocolate and let it sit for a minute. Using a small spatula, stir the chocolate gently until it is smooth. Let it sit on the counter until it reaches room temperature--it can't be the least bit warm when you add it to the whipped cream.

Working with the stand mixer with the whisk attachment or with a hand mixer in a large bowl, beat the remaining 1 cup heavy cream only until it holds the softest peaks. Turn the machine to high, add the cooled white chocolate all at once and continue to beat until the whipped cream holds firm peaks. Turn the whipped cream into a bowl, press a piece of plastic wrap gently against the surface to create an airtight seal and refrigerate for at least 2 hours, or up to 6 hours.

To Assemble the Cake:
If the tops of the cake layers have crowned, use a long serrated knife and a gentle sawing motion to even them. Slice each layer horizontally in half. Place one layer cut side down on a cardboard cake round or on a cake plate protected by strips of wax or parchment paper.

Remove the dark and white chocolate creams from the refrigerator and whisk each of them vigorously to loosen and smooth them. With a long metal icing spatula, spread enough dark chocolate cream (about 1 cup) over the cake layer to cover it completely. Top the cream with another cake layer, cut side up, and cover this layer with white chocolate whipped cream, making the white layer about the same thickness as the dark layer. Cover with a third layer, cut side up, and cover with another cup of so of the dark chocolate cream. (You'll have some dark chocolate cream left over--use it as a dip for madeleines or sables). Top with the final layer of cake, cut side down, and frost the sides and top with the remaining white chocolate whipped cream. If you'd like to decorate the top with chocolate shavings or curls, do it now.

Refrigerate for at least 3 hours, or overnight.
