Instructions
 

For the cake

  • Grease a jelly roll pan with my homemade cake release. (You can grease and flour, but I prefer cake release.) Set pan aside.
  • Preheat oven to 375° F.
  • Add flour and sugar to a medium-sized mixing bowl.
  • Whisk together and set aside.
  • Add butter, shortening, cocoa and water to a large saucepan and stir. Bring to a boil over medium-high heat.
  • Boil for 1 minute.
  • Remove saucepan from heat and add flour/sugar mixture. Stir to combine.
  • Add milk, cinnamon, vanilla, baking soda and eggs. Beat until combined.
  • Pour batter into prepared pan and bake for 15-20 minutes until a toothpick inserted into the middle of the cake comes out clean or with a few crumbs attached. (Mine is usually done in 15 minutes.)
  • Remove cake from the oven and cool on a wire cooling grid while you make the frosting.

For the frosting

  • Melt butter in a microwave-safe bowl or measuring cup in 20-second increments.
  • Add powdered sugar, melted butter, cocoa, milk and vanilla to a medium-sized mixing bowl.
  • Stir until combined.
  • Pour frosting onto warm cake.
  • Spread frosting evenly over cake with an offset spatula or a butter knife.
  • Let cake cool completely.
  • Cut into 16 even slices. Serve and enjoy!
