Ingredients

Cake

  • 2 cups granulated sugar
  • 1 3/4 cup all-purpose flour
  • 3/4 cup unsweetened cocoa powder
  • 1 1/2 tsp baking powder
  • 1 1/2 tsp baking soda
  • 1 tsp salt
  • 2 large eggs
  • 1 cup milk
  • 1/2 cup canola oil
  • 2 tsp vanilla extract
  • 1 cup boiling water

Frosting

  • 1/2 cup salted butter, softened
  • 2/3 cup unsweetened cocoa powder
  • 3 cups powdered sugar
  • 1/3 cup milk of choice
  • 1 tsp vanilla extract

Instructions

  • Preheat the oven to 350°F. Lightly spray a 9x13 inch baking pan with cooking spray and set aside.
  • In a medium bowl, mix together the sugar, flour, cocoa powder, baking powder, baking soda and salt. Add in the eggs, milk, vegetable oil and vanilla, and mix until fully incorporated.
  • Slowly mix in the boiling water. The batter will be very watery, and that is okay!
  • Pour the batter into the prepared baking pan, and bake in the preheated oven for 35-40 minutes, or until a toothpick inserted comes out clean. Allow to cool.
  • Meanwhile, in a medium bowl, cream together all of the frosting ingredients until smooth. Frost the cake once it is cool.
