Chocolate Sheet Cake Ingredients

For the Cake

  • 2½ cups all-purpose flour
  • 2 cups granulated sugar
  • 1 cup cocoa powder
  • 1 tablespoon baking powder
  • 1 teaspoon baking soda
  • ½ teaspoon salt
  • 3 large eggs
  • 1 cup vegetable oil
  • 1 cup milk
  • 1 cup hot coffee or hot water
  • 1 tablespoon vanilla extract

For the Chocolate Frosting

  • 1 cup butter
  • ½ cup cocoa powder
  • 4 cups icing sugar
  • ½ cup milk
  • 1 teaspoon vanilla extract
  • Chocolate sprinkles for topping

How to Make Chocolate Sheet Cake

Step 1: Prepare the Oven

Preheat your oven to 170°C (340°F). Grease a rectangular sheet cake pan or line it with parchment paper for easy removal.

Step 2: Mix the Dry Ingredients

In a large mixing bowl, whisk together the flour, cocoa powder, sugar, baking powder, baking soda, and salt until fully combined.

Step 3: Add the Wet Ingredients

Add the eggs, vegetable oil, milk, and vanilla extract to the dry ingredients. Mix until the batter becomes smooth and lump-free.

Step 4: Add Hot Coffee

Slowly pour in the hot coffee or hot water while stirring gently. The batter will become thin and glossy — this is what gives the cake its incredibly moist texture.

Step 5: Bake the Cake

Pour the batter into the prepared pan and spread evenly. Bake for 35–40 minutes, or until a toothpick inserted into the center comes out clean.

Step 6: Cool Completely

Remove the cake from the oven and let it cool completely before frosting.

How to Make Chocolate Frosting

In a saucepan, melt the butter over low heat. Whisk in the cocoa powder until smooth. Gradually add the icing sugar, then stir in the milk and vanilla extract. Mix until creamy and spreadable.

Spread the frosting evenly over the cooled cake and finish with chocolate sprinkles for the perfect touch.

Tips for the Best Chocolate Cake

  • Use hot coffee instead of water for a deeper chocolate flavor.
  • Do not overmix the batter after adding the hot liquid.
  • Let the cake cool fully before frosting to prevent melting.
  • Store leftovers in an airtight container for up to 4 days.
