Chocoloate Orange Layer Cake

Hello, most fabulous cake ever.  My birthday was right after Thanksgiving, and I had planned on making this for my birthday cake.  Then Thanksgiving happened, and life happened, and I couldn't even deal with cooking anything else.  So this is my belated birthday cake, and it was totally worth the wait!!  This rich fudgy chocolate cake is full of orange zest and chopped orange chocolate.  The frosting is thick and rich and smooth and also quite fudgy.  Altogether, this cake is pretty close to perfection, in my book!  Note:  I used Terry's Chocolate Oranges in this cake.  You can substitute regular chocolate chips and orange extract and more orange zest if you can't find the chocolate oranges.  Original frosting recipe found here.

Chocolate Orange Layer Cake

Cake:
3/4 cup cocoa powder
1 cup semi sweet chocolate chips
Zest of 2 oranges
3/4 cup boiling water
1 3/4 cup all purpose flour
1 1/2 teaspoons baking soda
1 teaspoon kosher salt
1 cup (2 sticks, 16 Tablespoons) butter, room temperature
2 cups brown sugar
4 eggs
2 teaspoons coffee extract
1 teaspoon vanilla extract
1 1/4 cups sour cream
1 1/4 cups chopped Terry's Chocolate Orange (or substitute milk chocolate chips)

Frosting:
12 ounces (2 chocolate oranges) Terry's Chocolate Orange
1/2 cup butter
8 ounces sour cream
1 Tablespoon light corn syrup
1 teaspoon vanilla extract
4 1/2 cups powdered sugar

Preheat the oven to 350F.  Lightly grease 2 9-inch round cake pans with cooking spray, then line the bottoms with parchment paper and lightly grease the parchment.  Set aside.

For the cake, place the cocoa powder, semi sweet chocolate chips, and orange zest in a medium bowl.  Pour the boiling water over the chocolate and stir until melted and smooth.  Set aside.  In a separate bowl whisk together the flour, baking soda, and salt.  Set aside.  In a large bowl, cream together the butter and brown sugar until light and fluffy.  Beat in the eggs, one at a time, followed by the coffee extract and vanilla, scraping down the sides of the bowl if necessary.  Beat the mixture until well blended.  On low speed, beat in 1/3 of the flour mixture, followed by 1/2 of the sour cream.  Repeat with another 1/3 of the flour and the remaining sour cream, finishing with the last of the flour.  Beat just until blended.  Add the chocolate mixture and beat on low until incorporated.  Stir in the chocolate chips. 

Divide the batter evenly between the two prepared pans and smooth the tops.  Place the cakes in the oven and bake for about 35 to 40  minutes, or until a toothpick inserted in the center comes out with a few moist crumbs.  Remove the cakes from the oven and place on a cooling rack to cool for about 10 minutes.  Run a knife around the edge of the cakes to loosen from the pans, then carefully turn the cakes out of the pans and let cool completely on a cooling rack.

For the frosting, place the chocolate oranges and butter in a microwaveable bowl, and microwave in 30 second intervals, stirring after each, until melted and smooth.  Using a hand mixer, beat in the sour cream, corn syrup, and vanilla until blended.  Beat in the powdered sugar on low speed until combined, then increase the speed and beat until the frosting is smooth.

To assemble the cake, place a cake layer on a serving plate and spread with frosting.  Place the second cake layer on top and frost the top and sides of the cake.  Makes 16 to 20 servings.

Enjoy!  -Cardamommy
