How do I make uniform sized brownie cupcakes?

-I have found that using cupcake tins for brownies is perfect, as you get chewy edges all the way around each brownie. However pouring the mix is soooo messy and getting the same amount in each mold is very tricky. Some people recommend scoops or measuring cups, but the mix is too thick to pour from cups and too thin for scoops. Also, if you use a pastry bag, how do you stop the flow between each one so it doesn't drip everywhere?Well I have seen Paula Dean and Giada di Laurentiis using little one or two ounce ice cream scoopers to deliver an exact measured amount.



I'm sure these are available at restaurant supply houses or at gourmet shops.



We used to use them to measure guacamole at a restaurant I once worked at.
