New Yorkers (especially Brooklynites) will wax nostaligic over this intensely chocolate cake. I remember having a piece as a little girl and I have never forgotten how wonderful and rich that little piece was. You will get a lot of utensils dirty making this cake, and it has a lot of preparation steps, but it is so worth it!

- In another bowl, whisk the egg whites until soft peaks form.
- Using a rubber spatula, gently fold the egg whites into the batter.
- Divide the batter between the prepared pans.
- Bake until a toothpick inserted in the center of a cakes comes out clean, about 45 minutes.
- Cool the cakes in the pans on a rack for 15 minutes.
- Gently remove the cakes from the pans and continue to cool.
- While the cake is baking, make the filling: Combine the cocoa and boiling water in a small saucepan over low heat.

- Return the top to the hat, if necessary, to melt the butter.
- 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 prior to using.
- Assemble the cake: Use a sharp serrated knife to slice each cake layer horizontally in half to form 4 layers.
- Set 1 layer aside.
- Place 1 layer on a cake round or plate.
- Generously swath the layer with 1/3 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 the sides of the cake.

- 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.
- Note: The filling ingredients make for a very runny filling, which is how a real Ebinger's cake should be.
- For those who desire a less syrupy consistency, they can stir in an additional 1 to 2 tablespoons of cornstarch.
