What don’t you get?!?! Just- WTF WHAT DONT YOU GET
Waffle don’t have more surface area than pancakes, because pancakes can be whatever size you want them to be, an advantage of pancakes, while waffles have to come out of a special press. Or you could roll your pancakes.
Same batter does not equal same flavor. It’s not always the same batter, but the differences in cooking make a difference texture, how well it absorbs things, and taste.
So if I put peanut butter inside one pancake and on top of another it would taste the same? I think not. Same with cream cheese, same with fruit, same with chocolate.
Dude just use your brain it’s not that hard.
