It's a month away, but we're having a pig roast for Michael's birthday, and i've been thinking about what kind of cake to bake. As if reading my mind, Twitter provided an answer. Somebody said that they'd found the perfect recipe - and it was mine. It's a cake I developed when I was living in Berkeley, working at the Swallow, and baking wedding cakes on the side. And it's the one I baked for Michael's birthday the first year that I knew him, the one in Comfort Me With Apples. And so here, courtesy of Serious Eats, is what I'll be baking again - all these years later.
Big Chocolate Cake
Serves 20-25. Adapted from Comfort Me with Apples by Ruth Reichl. This recipe makes a lot of cake and so would be perfect for a big party, but it also takes very well to freezing, even with the frosting on: after a couple of days I carved up our remaining cake and wrapped individual slices carefully in plastic wrap to freeze. Either warmed in the microwave or simply left out to come up to room temperature, the defrosted cake seemed (to us, at least) to have lost nothing in the way of taste and texture, even, amazingly, after a few months. If you are having a really big party, you can, Reichl says, double or triple the recipe as long as you adjust the baking timefor whatever size pans you are using.
Ingredients
For the cake:
1 1/2 cups boiling water
1 cup plus 2 tablespoons unsweetened cocoa powder (not Dutch process)
3/4 cup whole milk
1 1/2 teaspoons vanilla
3 cups all purpose flour
2 teaspoons baking soda
3/4 teaspoon salt
3 sticks (1 1/2 cups) unsalted butter, softened
1 1/2 cups firmly packed dark brown sugar
1 1/2 cups granulated sugar
6 large eggs
For the frosting:
5 ounces unsweetened chocolate, chopped
1 1/2 sticks (3/4 cup) unsalted butter, softened
1 cup whipped cream cheese
1 teaspoon vanilla
2 1/2 cups powdered sugar
1/8 teaspoon salt
Procedure
Preheat the oven to 350°F. Butter two 13x9x2inch baking pans; line bottoms with waxed or parchment paper and butterthe paper. Flour the pans (you can "flour" pans for chocolate cake with cocoa powder, if you like) and tap out excess.
Whisk together boiling water and cocoa until smooth. Then whisk in the milk and vanilla. Sift together the flour,baking soda, and salt.
If possible in a standing mixer, beat togetherthe butter and sugar until pale and fluffy. Add one egg at a time,beating well after each addition. On low speed, beat in the flourmixture in 3 batches and the cocoa mixture in 2, alternatingflour-cocoa-flour-cocoa-flour. The batter may look curdled.
Pour half of the batter into each pan and smoothtops. Bake in the middle of the oven until a tester comes out clean andthe cake begins to pull away from the pan, 25-35 minutes. Turn thecakes onto racks to cool completely.
Make frosting: melt the chopped chocolate in adouble boiler or in a bowl set over a pot of simmering water. Cool toroom temperature. Beat together the butter and cream cheese until lightand fluffy (I could not find whipped cream cheese in the store, so Ijust whipped it at home until it looked a little lighter and fluffierbefore adding the butter). Add the cooled chocolate and the remainingingredients and beat until thoroughly combined.
Assemble cake only when the cake layers have cooled completely.
