👨‍🍳 How to Make Chocolate Sheet Cake

Step 1: Prep the Oven
Preheat oven to 175°C (350°F). Grease and line a 9×13-inch sheet pan.

Step 2: Mix Dry Ingredients
In a large bowl, whisk together flour, sugar, cocoa powder, baking powder, baking soda, and salt.

Step 3: Add Wet Ingredients
Add eggs, milk, oil, and vanilla extract. Beat until smooth and well combined.

Step 4: Add Hot Liquid
Stir in hot water or coffee.
The batter will be thin—this is what makes the cake extra moist and soft.

Step 5: Bake the Cake
Pour batter into the prepared pan and bake for 30–35 minutes, or until a toothpick inserted in the center comes out clean.

Step 6: Cool Completely
Let the cake cool fully before adding frosting.
