Ingredients

• 2 cups All-purpose flour
• 1.5 cups Granulated sugar
• 0.5 cups Unsweetened cocoa powder
• 2 teaspoons Baking soda
• 1 teaspoon Baking powder
• 0.5 teaspoons Salt
• 1 cup Mayonnaise
• 1 cup Water
• 2 teaspoons Vanilla extract
• 0.5 cups Unsalted butter (for frosting)
• 2 cups Powdered sugar (for frosting)
• 0.25 cups Unsweetened cocoa powder (for frosting)
• 2 tablespoons Milk (for frosting)
• 1 teaspoon Vanilla extract (for frosting)

Directions

Step 1

Preheat the oven to 350°F (175°C). Grease and flour a 9x13-inch cake pan or two 8-inch round pans.

Step 2

In a large mixing bowl, whisk together the all-purpose flour, granulated sugar, unsweetened cocoa powder, baking soda, baking powder, and salt until well combined.

Step 3

Add the mayonnaise, water, and vanilla extract to the dry ingredients. Mix until the batter is smooth and free of lumps. Do not overmix.

Step 4

Pour the batter into the prepared pan(s), spreading it evenly.

Step 5

Bake for 30–35 minutes, or until a toothpick inserted into the center of the cake comes out clean.

Step 6

Remove the cake from the oven and let it cool in the pan for 10 minutes. Then transfer the cake to a wire rack to cool completely.

Step 7

To prepare the frosting, beat the unsalted butter in a medium bowl until creamy.

Step 8

Gradually add the powdered sugar and unsweetened cocoa powder, beating well after each addition.

Step 9

Add the milk and vanilla extract to the frosting mixture. Beat until the frosting is smooth and spreadable. Add additional milk, 1 teaspoon at a time, if needed for desired consistency.

Step 10

Once the cake has cooled completely, spread the frosting evenly over the top and sides of the cake.

Step 11

Slice and serve. Enjoy the rich, chocolatey goodness!
