Bumpy Cake Cupcakes

My wonderful neighbor Lisa had a birthday this weekend.  She's from Detroit, home to a culinary delight known as Bumpy Cake.  I really wonder how this cake developed; it is quite bizarre yet familiar.  The original Bumpy Cake came from a company in Michigan called Sanders.  Basically, it's a rich chocolate cake topped with rows of butter cream icing "bumps" and a layer of ganache over that. 
(Warning: I must emphasize here that I strayed incredibly far from my pseudo-vegan/health conscious roots here.  I even bought corn syrup....which is kind of magical.) Shh...don't tell.  I've never had good success with vegan ganache, but this vegan one was pretty great.

Here's my cupcake take:

Yield: 11 cupcakes

Ingredients for cake:
11/4 cups all-purpose flour
2 teaspoons baking soda
2 teaspoons baking powder
1/4 teaspoon salt
11/4 cups granulated sugar
4 ounces unsweetened chocolate, chopped
1 stick unsalted butter, cut into pieces
2 teaspoons vanilla extract
2 large eggs, lightly beaten

Ingredients for buttercream:
4 tablespoons unsalted butter, at room temperature
1 cup confectioners’ sugar
2 teaspoons vanilla extract
3 tablespoons heavy cream

Ingredients for ganache topping:
4 T cocoa
2 T oil
2 T + 4 t water
2 T dark corn syrup
2 C powdered sugar

Directions for the cake:
1. Position a rack in the center of the oven and preheat to 350. Place paper liners in a cupcake pan.
2. Sift together the flour, baking soda, baking powder and salt in a bowl.
3. Bring the sugar and 1 cup water to a boil in a saucepan, stirring until the sugar dissolves, about 3 minutes. Pour into a large bowl; add the chocolate and butter and let sit, stirring occasionally, until the chocolate is melted and the mixture has cooled slightly.
4. Stir in the vanilla. Using a mixer, beat in the eggs, then mix in the dry ingredients.
Divide the batter evenly between the prepared pans (about 1/4 cup batter per cupcake) and bake until a toothpick inserted in the center comes out clean, about 25 minutes. Cool in the pans for about 25 minutes, then transfer cupcakes to a rack to cool completely.

Directions for the butter cream:
Meanwhile, prepare the filling: Using a mixer, cream the butter until light and fluffy. Beat in 1/2 cup confectioners’ sugar. Add the vanilla and 1 tablespoon heavy cream; beat until smooth. Beat in the remaining 1/2 cup confectioners’ sugar and 2 tablespoons heavy cream in batches, alternating after each addition. Fill pastry bag and  set aside.

Directions for the ganache:
1. Mix all except sugar in a saucepan and heat, stirring, until hot. Mix in sugar and stir until smooth.

To assemble:
After cupcakes cool, pipe strips of butter cream on each cupcake. Freeze for at least 30 mins. Make ganache and once frozen, dip the cupcakes into the ganache. Refridgerate until set. Enjoy with a large glass of cold (almond or soy) milk!
