First, start by preheating the oven to 350°F (180°C). Line a 9×13-inch baking pan with non-stick baking paper and some cooking spray.


First, combine the butter and water in a medium saucepan and bring them to a boil.


Next, whisk in the eggs one at a time. Make sure to whisk each until they are fully incorporated before adding another. Finally, whisk in the vanilla extract or essence.


Now, in a large mixing bowl, combine all of the dry ingredients. Make sure they are lump-free and well mixed.
