Bars to gain weight?

Hello.
I'm a 16 year old girl who is 5'4 and weighs 98 pounds. My doctor tells me that I am underweight, which I am. Only, I eat a ton of food and I don't have any problems (like anorexia). I just have a very high metabolism. So my question...

is...are there any bars that are extremely high in calories/protein that could help me gain weight healthily?

snickers, 3 musketeers, other bars that have a lot of items on the bar.

im 5'3 and 101 .

so we are pretty close .

chocolate bars are not the best way to go...
Try protein bars, you'll find them at pharmacies or supermarkets...
