Line an 8-inch or 9-inch square baking dish with wax paper and set aside.

In a large mixing bowl, stir together the oatmeal, 1 cup of the chocolate chips, the peanut butter and vanilla extract.

Combine the rest of the chocolate chips, sugar, milk, butter, and salt in a saucepan and cook over medium heat. Bring to a full boil (there should be bubbles covering the entire surface) and boil for 2 minutes.

Pour the mixture over the oatmeal mixture and quickly stir to combine until well moistened.

Press it evenly into the pan using the back of a spoon.

Allow the bars to sit about 30 minutes before cutting into bars.
