This document provides instructions for making a sponge cake. It lists the ingredients needed which include flour, butter, eggs, baking powder, and milk. The instructions state to cream the butter and sugar until pale and fluffy, then mix in the eggs one at a time. The dry ingredients are folded into the wet ingredients until just combined. The batter is then poured into a greased cake tin and baked at 180C for approximately 20 minutes, until a toothpick inserted in the center comes out clean. The cake is allowed to cool completely before removing from the tin.
