Unless you're crafting a cake from a box, you're going to be mixing a fair amount of thick, hard-to-churn butter and batter. Therefore, you're going to need a hefty, sturdy mixer to combine the main ingredients. Trust us -- you don't want to try creaming all that stuff together by hand. It's exhausting work, and, truth be told, quality mixers just do a better job creating lump-free batter than any human hand. Before you turn on the mixer, ensure that it's sitting on an even, clutter-free surface. And remember that ingredients combine better when they're all at the same temperature.
