Barefoot Bloggers- Sheet Cake

I am a day late with my first Barefoot Bloggers. What a crazy week I had...it seems that every time we have a holiday weekend we pay for it by having to jam 5 days worth of work into 4 days. Thank God, the weekend is here!!! Going back to Barefoot Bloggers again...The first September recipe was chosen by Susy of Everyday Gourmet. She chose Birthday Sheet Cake. For the record, I LOVE Ina and every single recipe I've ever made of hers (and I made LOTS) I was very happy with...with this being said, I was somewhat disappointed with this one... The cake flavor was good but the ganache frosting was kind of runny and didn't quite set the way it should... I also thought that is was a boring recipe. There was nothing special about it. Essentially, it was a yellow cake with very blahhh chocolate frosting. I can't believe that I just wrote Ina and blahh in the same post but this cake didn't do anything for me. To be fair, I am not a huge cake fan, so it was a hard sale to begin with. The bottom line is that if you like yellow cake with chocolate frosting you probably will like this cake. I mentioned earlier that it was a sheet cake, but I do not like sheet cakes, so I decided to stack my cakes and make 3 layer cake covered in frosting. Here is what I've ended up with:




For the cake:

* 18 tablespoons (2 1/4 sticks) unsalted butter, at room temperature
* 3 cups sugar
* 6 extra-large eggs, at room temperature
* 8 ounces (about 1 cup) sour cream, at room temperature
* 1 1/2 teaspoons pure vanilla extract
* 1 lemon, zested
* 3 cups all-purpose flour
* 1/3 cup cornstarch
* 1 teaspoon kosher salt
* 1 teaspoon baking soda

For the frosting:

* 24 ounces semisweet chocolate chips
* 1 1/2 cups heavy cream
* 2 tablespoons light corn syrup
* 1/2 teaspoon pure vanilla extract
* 4 tablespoons (1/2 stick) unsalted butter, at room temperature


Directions

Preheat the oven to 350 degrees F. Butter and flour a 12 by 18 by 1 1/2-inch sheet pan.

To make the cake, cream the butter and sugar on medium-high speed in the bowl of an electric mixer fitted with a paddle attachment until light and fluffy, about 5 minutes. On medium speed, add the eggs, 2 at a time, then the sour cream, vanilla, and lemon zest, scraping down the bowl as needed. Mix well. Sift together the flour, cornstarch, salt, and baking soda. With the mixer on low speed, slowly add the flour mixture to the butter mixture and stir just until smooth. Finish mixing by hand to be sure the batter is well mixed. Pour evenly into the pan, smooth the top with a spatula, and bake in the center of the oven for 25 to 30 minutes, or until a toothpick comes out clean. Cool in the pan to room temperature.

For the frosting, place the chocolate chips and heavy cream in a bowl set over a pot of simmering water, stirring occasionally, until the chips are completely melted. Off the heat, add the corn syrup and vanilla and allow the chocolate mixture to cool to room temperature. In the bowl of an electric mixer fitted with the whisk attachment, whisk the chocolate mixture and softened butter on medium speed for a few minutes, until it's thickened.

Spread the frosting evenly on the cake. Have the children decorate the cake with chocolate candies.
