Ingredients

• 2 cups All-purpose flour
• 1.5 cups Granulated sugar
• 0.75 cups Unsweetened cocoa powder
• 1.5 teaspoons Baking soda
• 1 teaspoons Baking powder
• 0.5 teaspoons Salt
• 1 cups Mayonnaise
• 1 cups Water
• 1 teaspoons Vanilla extract
• 3 cups Powdered sugar
• 0.5 cups Butter (softened)
• 3 tablespoons Strong brewed coffee (cooled)
• 0.25 cups Unsweetened cocoa powder (for frosting)
• 1 teaspoons Vanilla extract (for frosting)

Directions

Step 1

Preheat your oven to 350°F (175°C) and grease a 9x13-inch baking pan or two 8-inch round pans. Set aside.

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. Stir with a wooden spoon or rubber spatula until the batter is smooth and fully combined. Avoid overmixing.

Step 4

Pour the batter into the prepared pan(s) and smooth the top with the back of a spoon or spatula.

Step 5

Bake in the preheated oven for 30-35 minutes, or until a toothpick inserted into the center comes out clean.

Step 6

Remove the cake from the oven and allow it to cool completely in the pan(s) on a wire rack before frosting.

Step 7

To make the mocha frosting, combine the softened butter, powdered sugar, unsweetened cocoa powder, and cooled brewed coffee in a medium bowl. Beat with an electric mixer until light and fluffy. Add the vanilla extract and mix until smooth.

Step 8

Spread the mocha frosting evenly over the cooled cake. If you baked two round layers, assemble the cake by frosting the top of the first layer, stacking the second layer on top, and then frosting the top and sides.

Step 9

Slice and serve the cake at room temperature. Store any leftovers in an airtight container at room temperature for up to 3 days, or refrigerate for longer storage.
