My take on a vintage recipe, this Kicked Up A Notch Texas Sheet Cake is a moist, rich, chocolate cake with a cooked, fudgy icing that makes this dessert a crowd pleaser.
Combine the butter, coffee, and cocoa in a saucepan over medium heat until melted. Next, add the sugar, flour, salt, eggs, baking soda, sour cream, and vanilla. Mix well using a spatula or wooden spoon. Remove the saucepan from the heat.
Pour the mixture into a lightly greased 15x10x1-inch jelly roll pan. Sprinkle the chopped chocolate on top. Bake in a preheated 350-degree oven for 20 minutes until done. Do not over bake.
Meanwhile, make the frosting. In the same pan (you don’t even have to wash it. Yay, one less pot/bowl.) melt the butter, cocoa powder, buttermilk, and half & half over medium heat, stirring often. Allow this mixture to come up to a gentle boil. Remove the pan from the heat and stir in the powdered sugar (you will be grateful to have sifted this about right now.) and the pecans or toffee bits, if you are going to ‘gild the lily’ – this is optional but delicious.
Try to restrain yourself from licking the spoon, your fingers, or anything else you may dip into this luscious concoction.
When the cake is done, remove the pan from the oven and IMMEDIATELY pour the frosting over the hot cake. Spread to cover. Allow it to cool completely.
Cut into squares and enjoy. Pour yourself a tall, cold, glass of milk. You’re gonna need it!
