<human>:  How do I make a birthday cake from scratch?
<bot>: To make a birthday cake from scratch, you will need to gather the ingredients and measure them out correctly. Preheat your oven according to the recipe instructions and grease the baking pan you are using. Combine the dry ingredients in one bowl and the wet ingredients in another, then mix them together. Pour the batter into the pan, place it in the oven, and bake it until the center is fully set. Allow the cake to cool before frosting and decorating it.
