<human>:  How do I bake a perfect vanilla cake?
<bot>: To bake a perfect vanilla cake, you will need to start by preheating your oven to 350°F. Then, prepare your cake pans by greasing them with butter or margarine, and dust lightly with flour. Next, mix together the dry ingredients, including all-purpose flour, baking powder, and salt. In a separate bowl, cream together the butter and sugar until light and fluffy. Add the eggs one at a time, beating until incorporated. Then, beat in the vanilla extract and combine the wet and dry ingredients. Finally, pour the batter into the prepared pans and bake for about 25-30 minutes, or until a toothpick inserted into the center of the cake comes out clean. Let the cake cool completely in the pans before serving.
