This is a copy of Ebinger's bakery from Brooklyn NY that closed in 1972. The filling should have a runny consistency, but if you want it more like pudding use the 4 tablespoons corn starch. Ingredients:
cake |
1/2 cup unsweetened dutch-process cocoa powder |
2 tablespoons boiling water |
2 ounces unsweetened chocolate, chopped |
3/4 cup milk |
1 cup (2 sticks) unsalted butter, softened slightly |
2 cups sugar |
4 large eggs, separated |
2 teaspoons vanilla extract |
2 cups all-purpose flour |
1 teaspoon baking powder |
1 teaspoon baking soda |
1 teaspoon salt |
filling |
1 tablespoon plus 1 3/4 teaspoons unsweetened dutch-process cocoa powder |
2 cups boiling water |
3/4 cup plus 1/2 teaspoon sugar |
1 ounce bittersweet chocolate, chopped |
4 tablespoons cornstarch dissolved in 1 tablespoon cold water (use 2 tablespoons cornstarch for a runnier filling) |
1/4 teaspoon salt |
1 teaspoon vanilla extract |
2 tablespoons unsalted butter |
frosting |
12 ounces semisweet |
chocolate, chopped |
12 tablespoons (1 1/2 sticks) unsalted butter |
1/2 cup hot water |
1 tablespoon light corn syrup |
1 tablespoon vanilla extract |
Directions:
1. CAKE
2. Preheat oven to 375 degrees. Butter and lightly flour two (8-inch) round cake pans. Place cocoa in a small bowl and whisk in boiling water to form a paste.
3. Combine the chopped chocolate and milk in saucepan over medium heat. Stir frequently until the chocolate melts, about three minutes. Remove from the heat. Whisk a small amount of the hot chocolate milk into the cocoa paste to warm it. Whisk the cocoa mixture into the milk mixture. Return the pan to medium heat and stir for one minute. Remove and set aside to cool until tepid.
4. In the bowl of a mixer, cream the butter and sugar together. Beat in the egg yolks, one at a time, and the vanilla. Slowly stir in the chocolate mixture. Combine the flour, baking powder, baking soda and salt. Using a spatula or a wooden spoon, slowly add the flour mixture to the chocolate mixture. Fold in until just mixed. In another bowl, whisk the egg whites until soft peaks form. Using a spatula, gently fold the egg whites into the batter. Divide the batter between the prepared pans. Bake until a toothpick inserted in the center comes out clean, 45 minutes. Cool the cakes in the pans on rack for 15 minutes.
5. Gently remove the cakes from the pans and continue to cool.
6. FILLING
7. While the cake is baking, combine the cocoa and boiling water in a small saucepan over low heat. Stir in the sugar and chocolate. Add the dissolved cornstarch paste and salt to the pan and bring to a boil, stirring constantly. Boil for one minute. Remove from heat and whisk in vanilla and butter. Transfer the mixture to a bowl, cover and refrigerate until cool.
8. FROSTING
9. Melt the chocolate in a double boiler over hot, not simmering, water, stirring until smooth. Remove the top of the double boiler from the heat and whisk in the butter, one tablespoon at a time. Return the top to the heat, if necessary, to melt the butter.
10. Whisk in the hot water all at once and whisk until smooth. Whisk in the corn syrup and vanilla. Cover and refrigerate for up to 15 minutes before using.
11. Assemble the cake: Use a sharp serrated knife to slice each cake layer horizontally in half to form four layers. Set one layer aside. Place one layer on a cake round or plate. Generously swath the layer with one-third of the filling. Add the second layer and repeat. Set the third layer on top. Quickly apply a layer of frosting to the top and sides of the cake. Refrigerate for 10 minutes.
12. Meanwhile, crumble the remaining cake layer. Apply the remaining frosting to the cake. Sprinkle it liberally with the cake crumbs. Serve the cake within 24 hours. Store in a cool place.
