Cake For Breakfast

I had some yummy {Market Street Grill} chocolate cake last night for dessert and then helped myself to some for breakfast this morning.
I love that Market Street actually gives you some of their recipes. I would rather just buy the cake than make it, but for those that would like to make it here is the recipe.



INGREDIENTS:
Buttercream
12 egg yolks
½ cup sugar3
tablespoons water
1 pound butter, room temperature
½ pound chocolate, melted (dark, semi-sweet)
1 teaspoon rum, dark
1 teaspoon vanilla
pinch salt

Cake
13 eggs
1 cup sugar
1 ¾ pounds, butter, room temperature1
¾ pounds chocolate, melted and somewhat cooled
2 ½ ounce cornstarch - by weight
2 ½ ounce flour - by weight
Pinch salt
1 teaspoon vanilla

METHOD:
Buttercream
Beat yolks and salt until very thick and light lemon colored (at least 10 minutes) on high speed - while yolks are beating, combine sugar and water in small saucepan and cook to soft-ball stage (240 degrees). Pour syrup in slow stream into peaks while continuing to beat on high. Continue beating until cool. Add butter and beat until well combined. Add melted chocolate and combine well. Add rum and vanilla and combine well. Use immediately. Leftovers should be refrigerated and re-whipped until softened.

Cake
Beat eggs with sugar and salt until very thick and at least doubled in volume. Add softened softened butter and beat until well combined and thick. Add melted chocolate and beat, scraping down sides of bowl until well combined. Add flour and cornstarch and vanilla and combine well.
Turn into 2 18 x 14 (approximately) baking sheets that have been lined with parchment and oiled. Smooth batter and bake at 350 degrees for 35 - 45 minutes. Batter will rise up and fall back and pull away from side of pan.

Cook and refrigerate layers in the pans until chilled or overnight.

TO ASSEMBLE:Loosen edges of cakes and invert on flat surface. Peel paper off and cut each layer lengthwise into four. Layer four strips of cake with three layers of buttercream in between (cake on bottom and top). Buttercream should be about ½" thick. Smooth sides of any that has oozed out and glaze top with melted chocolate or gnache. Let set and cut into loaves.
