You make a cake by blending together flour, baking powder, sugar, butter, eggs, and milk into a smooth and creamed batter. Transfer the batter into greased baking pans and cook in an oven preheated to three hundred and fifty degrees until golden brown. Let the cake cool on a wire rack so the texture sets properly before adding icing or decorations. Spreading buttercream or ganache over the layers completes your classic homemade dessert.
