I am going to make a batch of pancakes (about seven two-pancakes servings). I'm new to making pancakes (I've just started this fall) but I've found I'm pretty good at it... usually. This time, I would like to add two sliced bananas and about a cup of raspberries to the plain batter. Do I need to adjust the dry ingredients for this? Just a bit of extra flour? Or do nothing at all?
