Butter (or grease with shortening) the bottoms and sides of the cake pans and 4 cupcake cavities. Dust them with flour then turn the pan upside down to allow the excess flour to fall out. Line the round cake pans with a round piece of parchment paper to guarantee the cake won't stick to the pan. I don't recommend lining the cupcake pans with liners as you want the cupcake to bake directly in the muffin tin so that you get a nicely shaped cupcake that is the right size. A liner will create a smaller cupcake with ridges.
