Chocolate cake. One of the best desserts ever, and is a lot of people’s favourite – including mine. Today, I bring you my Chocolate Sheet Cake. A deliciously moist and fluffy chocolate cake baked in a rectangle baking tray and generously topped with a creamy chocolate buttercream frosting. I’ve spiced this cake with a little cinnamon to give it an ‘autumn’ taste, and it really does pair well with the chocolate flavour!

For the chocolate buttercream, I topped the cake with a thin layer, then I piped swirls onto each slice. Leave about 1/2 – 1 cup of frosting for the swirls, and spread the rest on the cake.

Chocolate Sheet Cake

A deliciously moist and fluffy chocolate cake spiced with cinnamon and topped with chocolate buttercream frosting!
Prep Time 25 minutes
Cook Time 20 minutes
Total Time 45 minutes
Yields 15 slices

Ingredients

For the Cake

  • 2 cups cake flour* 200g
  • 1/2 cup cocoa powder 50g
  • 1 teaspoon baking soda
  • 1/2 teaspoon baking powder
  • 1/2 teaspoon salt
  • 2 teaspoons ground cinnamon
  • 3 large eggs room temperature
  • 1 and 1/4 cups light brown sugar 250g
  • 2 teaspoons vanilla extract
  • 1/2 cup unsalted butter 115g, melted
  • 3/4 cup greek yoghurt 175g

For the Frosting

  • 4 cups icing/powdered sugar 500g
  • 1 cup unsalted butter 226g, softened
  • 1/2 cup cocoa powder 50g
  • 3 - 4 tablespoons milk
  • 1 teaspoon vanilla extract

Instructions

For the Cake

  1. Preheat the oven to 180C/350F/Gas 4. Grease a 13x9-inch pan, and set aside.
  2. Whisk together the flour, cocoa powder, baking powder, baking soda, salt, and cinnamon. Set aside.
  3. Whisk together the eggs. Add the sugar, and whisk until combined. Add the vanilla extract, butter, and yoghurt and whisk until combined. Gradually fold in the dry ingredients.
  4. Pour the batter into the prepared pan, and spread out evenly. Bake for 18 - 20 minutes, or until a toothpick inserted into the centre comes out clean. Allow to cool completely in the pan on a wire rack.

For the Frosting

  1. Using a handheld or stand mixer, beat together the butter and icing sugar until light and fluffy. Beat in the cocoa powder, milk and vanilla until smooth, and spreadable. Add more milk if needed.
  2. Spread the frosting evenly over the cooled cake (leaving about 1/2 - 1 cup for piping). Transfer the remaining frosting to a piping bag and pipe swirls on each slice of cake. Garnish with sprinkles.

Notes

*Make your own cake flour! Measure out 2 cups (250g) of plain/all-purpose flour, remove 4 tablespoons, and replace with 4 tablespoons of cornflour/cornstarch. Sift well.

      It shouldn’t be too thick, but definitely not too runny.

    hi Marsha,
    Just saw this lovely chocolate cake recipe after your vanilla sheet cake. can i know will this cake rise up high like your vanilla sheet cake recipe. I needed to bake for my son’s birthday as a soccer pitch( did wrote in your other comments too) Can I use this cake to frost it as a soccer field cake?
    I don’t like the taste of cinnamon, is there any other ingredient to replace it?
    Thanks again…looking forward to your reply.

      Hi Evelyn! This chocolate cake isn’t the same thickness as the vanilla one, so I would make the vanilla one and replace half cup of flour with cocoa powder, and just make the frosting as instructed on the chocolate cake recipe. Cinnamon is optional, so you can totally leave it out! πŸ™‚
