For the Chocolate Sheet Cake:

Preheat oven to 350°(F). Generously spray a 9x13-inch baking pan with non-stick spray and set aside until needed. 

  1. In a large glass bowl, microwave the chocolate, butter, and oil in 30 second increments, stirring between each increment, until butter and chocolate are completely melted. Whisk smooth and set aside.
  2. In a large bowl combine cocoa powder, both sugars, flour, baking soda, and salt until ingredients are thoroughly combined. Set aside.
  3. In a separate large bowl, combine the eggs, yolk, sour cream, milk, and vanilla, beating until well combined. 
  4. Pour in the chocolate mixture and stir until combined. Add the dry ingredients into the wet ingredient mixture and mix until just combined.
  5. Carefully add in hot coffee (or water) and let sit for 1 minute. Then gently stir until completely combined. The batter will be very thin. 
  6. Pour batter into pan and smooth the top. Bake in preheated oven for 38 to 45 minutes, or until wooden toothpick or cake tester inserted in the center of a cake comes out clean or with just a few moist crumbs attached.
  7. Place cake on a cooling rack to cool completely. Once cool, spread frosting on top of cake.
