I absolutely love pancakes!  How about you?
I will eat them but they're not my favorite. I make them for my kids though since they are so easy to fry up in a griddle or frying pan.
Do you usually make plain or do you add stuff like blueberries or chocolate chips, etc.?
Yes ocassionally I will use chocolate chips, or small chunks of sweetened chocolate, in my pancakes. My kids love that.
When did the pancake come into popularity?
Actually archaeologists have found evidence that pancakes were enjoyed by prehistoric societies!
Oh my gosh!  I had no idea!  Were they pretty much the same?
I'm not sure but I do know that the shape and structure of a pancake varies worldwide.
