In a large bowl mix the pancake mix, water, cinnamon and vanilla. Whisk until lumps are gone but don't over mix and then let your mix stand 1-2 minutes to thicken.
Heat a large skillet and spray with non stick spray. Slice up your bananas and put in bowl. Pour slightly less than 1/4 cup of batter onto skillet. When pancakes bubble and bottoms are golden flip over to cook other side, and finish making rest of pancakes and keep them warm in a large pot on stove.
Place your stack of pancakes on plate and loaded them as picture shows,add butter and syrup. Enjoy!
