Grease an 8X8 inch Baking pan and line it with parchment. Set aside. Preheat oven to 350F.
Combine the first 6 ingredients in a bowl.
Melt the oil and peanut butter together in low heat. You can alternatively do it in a microwave for 15-20 seconds.
Once melted, stir in the sugar, honey and vanilla.
Pour this wet mixture into the oat mixture and stir until the dry ingredients are coated.
Touch this mix to make sure its not hot (cool it down if it is) before adding the egg white. Stir until evenly distributed.
Pour it inside the prepared baking dish and press it down firmly. You can use a spatula or another parchment/plastic wrap to press it down to the dish.
Sprinkle the chocolate chips and press them lightly into the oats.
Bake it for about 25-30 minutes until golden on the edges. Allow to cool before cutting into 12 bars.
