You make a cake by mixing dry ingredients like flour, baking powder, and salt with wet ingredients such as butter, sugar, eggs, and milk until smooth. Pour the prepared batter into greased baking pans and bake at three hundred and fifty degrees for about twenty five to thirty minutes. Check for doneness by inserting a toothpick into the center to see if it comes out clean. Allow the baked layers to cool completely before applying your favorite frosting.
