<human>:  I want to bake a cake. What ingredients do I need and how should I bake it?
<bot>: Ingredients: You will need flour, sugar, baking powder, salt, butter, eggs, and milk. 
Instructions: Preheat your oven to 350°F (175°C). Grease and flour a 9x13 inch baking pan. In a medium bowl, whisk together the flour, sugar, baking powder, and salt. In a separate bowl, beat the butter until creamy. Add the eggs and mix until combined. Add the milk and mix to combine. Slowly add the dry ingredients to the wet ingredients and mix until combined. Pour the batter into the prepared baking pan and spread evenly. Bake at 350°F (175°C) for 25 minutes, or until a toothpick inserted in the center comes out clean. Let cool before serving. Enjoy!
