Cherry Limeade Dump Cake
I found key lime pie filling at my grocer. If you can't find it, substitute lemon meringue pie filling and you can have a Cherry Lemonade Cake.
It's not quite done yet, but I can smell it - and it smells just like a Sonic Cherry Limeade! Can't wait to try a piece.
DONE: This cake is really more of a cobbler - great flavor, really tastes like a cherry limeade!
