Can someone give me information on square cupcakes(cupcakes that are square).What kind of bakeware is needed and where would I get it?
You might just bake a sheet cake and cut them out with a square cookie cutter.
There's a bunch for sale on Amazon - http://www.amazon.com/s?ie=UTF8&keywords=square%20cupcake%20pan&rh=i%3Aaps%2Ck%3Asquare%20cupcake%20pan&page=1
Google them - a lot come up!
I found my square cupcake pan at Wal-Mart with the other bakeware. And...regular cupcake wrappers fit!
I also found my pan at Walmart. I use my pan for making brownies. I am sure it can be used for cupcakes.
