Instructions
Cake
Preheat the oven to 350°F and prepare a 9x13-inch baking dish with nonstick cooking spray.
Whisk the flour, baking soda, cocoa powder, and sugar in a medium mixing bowl until fully combined.
In a large mixing bowl, beat the mayonnaise, vanilla, and water with a fork or whisk until smooth and fully combined.
Add the dry ingredients to the wet ingredients and mix, using an electric mixer for best results.
Spread the cake batter evenly in the prepared baking dish using the back of a spoon or rubber spatula and bake for 35 to 40 minutes, until a toothpick inserted into the center of the cake comes out clean.
Place the baking dish on a wire rack and allow the cake to cool completely.
Frosting
Combine all the frosting ingredients in a medium bowl and blend until smooth. The frosting may be difficult to mix at first, but only add more milk if absolutely necessary to reach a smooth texture, adding ½ tablespoon at a time. The frosting should be smooth, thick, and slow to fall off a spoon, but also malleable and spreadable.
After the cake has cooled completely, spread the frosting evenly over the top of the cake and serve immediately or allow the frosting to set slightly before serving.
Notes
For a richer flavor, add 1 tablespoon of Nespresso to the dry ingredients.
