Chocolate Volcano Birthday Cake

Chocolate Volcano Birthday Cake

I designed this cake with kids in mind. Its fun dome shape can be transformed into a flower, a ladybug, or a spider, and the filling is sweet and simple. If you prefer, bake it in standard cake pans instead of a bowl, and frost it with a traditional butter cream icing.


Chocolate Cake
1 cup unsalted butter, softened
1 1/2 cups sugar
2 eggs
2 cups flour
3/4 cup cocoa powder, sifted
1 teaspoon baking soda
1 teaspoon baking powder
1 1/2 cups sour cream
Cream Filling
1 cup heavy whipping cream 1/4 cup sugar
1/2 teaspoon pure vanilla extract
Chocolate Glaze
1 cup heavy whipping cream
12 ounces bittersweet chocolate, coarsely chopped
1 cup heavy whipping cream, whipped, as an accompaniment
Fresh edible flowers, such as pansies, lilacs, or nasturtiums, for garnish
Bittersweet chocolate shavings, for garnish.

To prepare the cake:

Preheat the oven to 350 degrees. In the bowl of a heavy-duty mixer, beat the butter and sugar until creamy and a pale yellow color. Beat in the eggs, one at a time, mixing well after each addition.

Add 1 cup of the flour, the cocoa powder, baking soda, and baking powder,
and beat well.

Add the sour cream and beat well. Add the remaining flour and beat until

Pour the batter into a well-greased 4-quart metal bowl and bake until a
knife inserted in the cake comes out clean, 35 to 40 minutes.

Let cool for 10 minutes, and then flip the bowl over onto a rack to release
the cake. Let cool completely. To prepare the filling and fill the cake:

Whip the cream, sugar, and vanilla until the cream holds soft peaks. Using a
long, serrated knife, split the cake by cutting off a 1/2-inch-thick slice
from the cake’s flat base. Turn the cake over so the flat side is facing up.
Carefully scoop out the inside of the cake, setting aside 1 cup of cake
crumbs, leaving a 1-inch-thick shell of cake all around.

Gently fold the reserved cake crumbs into the whipped cream. Fill the
hollowed-out cake with the whipped cream mixture, set the 1/2-inch-thick
base on top, and refrigerate for 1 hour.

To prepare the glaze:

Heat the cream in a saucepan over high heat just until it comes to a boil.

Meanwhile, place the chocolate in the bowl of a food processor and process
until finely chopped. With the machine running, pour the hot cream through
the feed tube and process until smooth. Transfer the glaze to a bowl and
let cool for 10 minutes.

To glaze the cake: Place the cake, round side up, on a rack set in a baking
sheet. Pour the glaze over the cake, letting it run down the sides to cover
the cake completely. Refrigerate for at least 2 hours, or up to 24 hours.

To serve: Transfer the cake to a platter. Garnish with whipped cream, fresh
flowers, and chocolate shavings.
