Can you use a measuring cup for butter?

While measuring cups can technically be used for measuring solid fats or ingredients not intended for cups, such as butter; this practice results in a less accurate measurement. Solid fats or sticky ingredients don't pour into and out of these tools easily and consistently the way liquids do which means you can end up with more and less depending on if your scoop it or pack it.

Using the water displacement method can give you a much more accurate reading for most solid ingredients to measure as well as prevent messes
