In my opinion, the greatest food hacks are the ones that help you cut way, way down on dishwashing. That's especially true when it comes to baked goods, which usually involves dirtying up a couple of mixing bowls, measuring cups and spoons, some kind of stirring implement, and the baking pan itself.
Over at Yammie's Noshery, the Yammie in question came up with a recipe for banana bread muffins that requires only one measuring spoon and one measuring cup. All the ingredient proportions are based on either ¼ of a teaspoon or ½ a cup.
You simply put all of the ingredients in a ziplock plastic bag and mash them around until they're thoroughly mixed together. Then, snip a small corner (make sure it's small, since the batter will be runny) off the end of the bag and dispense it into the muffin cups.

If you don't have a cupcake pan handy, never fear: there are ways to make your own.
This hack would also work well with other pastry-related items like icing and pancake batter, too. Plus, putting it in a plastic bag makes it easy to dispense the icing/batter in fancy shapes without investing in other tools.
One more tip: if you're of the waste-not-want-not school of cooking, there's no need to break out a brand-new plastic bag just for this hack. I tend to reuse and even re-wash plastic bags multiple times. I'd pick out a bag that was just about on its last legs to use for this trick—as long as it didn't have any holes in it, of course.
