I had pancakes for breakfast this morning
Then you had a very ancient breakfast! Archaeologist believe pancakes were probably the earliest and most eaten cereal food back in prehistoric times.
Really?  I had no idea!  I wonder how they were different back then
Probably more like the British pancake, which is often unleavened and like the French crepe. In the US baking powder is often used.
I use baking powder in mine.  What kinds of toppings can be used?
Whatever you like. A variation from southeast Europe is a thin pancake fried on both sides and filled with jelly, cream cheese or ground walnuts. Any sweet or savory topping would work.
That sounds kind of like a doughnut.  Do most cultures have a version of the pancake?
Yes, they do and their shape and structure, i.e. thick or thin, round or oval, varies from country to country.
I might just have pancakes again for dinner now!
