"Have you ever had a cherrychanga? Ooh! Sorry, that was a question." - Pinkie Pie
Pinkie Pie invents the cherrychanga in The Last Roundup. She only mentions mashed-up cherries in a deep-fried tortilla, so I'd call the cream filling optional. I do think it adds more flavor depth (read: tastes delicious), and makes the recipe akin to that of strawberry cheesecake chimichangas.
Incidentally, you know who also likes saying funny words like 'chimichanga'? Deadpool. Wonder if those two would ever get along...
