Susy of Everyday Gourmet has chosen Birthday Sheet Cake for our first recipe of September.
When I looked at the recipe I though holey moley my arteries are going to be screaming.. lol.. This recipe is not for the person watching their weight.
I did make the cake with one change, instead of using a sheet pan I split the batter between two 8x8 square pans. This way I wouldn't be so tempted to eat the whole cake while home during the day.
I thought it was a tasty cake, especially the chocolate frosting.
Birthday Sheet Cake
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
Chocolate candies for decorating (recommended: M&M's)
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.
