To make a cake, you need to gather supplies like a bowl, flour, sugar, baking powder, milk, shortening, eggs, and a baking pan. You combine the dry ingredients, then add wet ingredients like milk and shortening and mix. Pour the batter into the greased pan and bake at 350 degrees for 30-35 minutes until a toothpick inserted comes out clean. Allow the cake to cool before cutting into pieces and serving.
