I've had sugar cream pie in Ohio and Pennsylvania for years. The amish like to make that one around here. I have gotten them at a few bakeries too.maybe just central Indiana. I just googled it though and learned that it is also the official state pie. I didn't even know there were official state pies
"Also known as Hoosier Pie, a resolution to name the sugar cream pie as Indiana's State Pie passed in the State Senate in 2009. This Indiana tradition harkens back to early Amish and Shaker communities. "
My favorite is probably chicken pot pie, but if I had to go sweet, I'd say egg custard pie or banana cream pie.
