First, gather your ingredients: flour, sugar, eggs, butter, and leavening agents. Next, cream the butter and sugar until light and fluffy, then beat in the eggs and vanilla. Combine the dry ingredients separately, then alternate adding them with milk to the wet mixture, mixing until just combined. Pour the batter into a prepared pan and bake until a toothpick inserted comes out clean. Finally, let the cake cool before decorating or serving your delicious creation.
