Preheat your oven to 350°F. Line a 9x9 inch square pan with parchment paper, and set aside.
Spread your oats into an even layer on a medium sized baking sheet. Bake in the center of your preheated 350°F oven for 8 to 10 minutes, pausing halfway to toss the oats. They won't look significantly different, but they'll have just started to brown along the edges. Transfer the oats to a large bowl, and set aside while you work on the wet ingredients.
For the wet ingredients, combine honey, brown sugar, butter, and salt in a medium sized saucepan. Place over medium-high heat, and heat, stirring occasionally, until the mixture boils. Boil for about 1 minute, then set aside for 5 minutes to cool slightly.
Add the honey mixture to the oats (they'll both probably still be hot, but that's fine!) Mix together until combined.
Add your chocolate chips to the oat mixture, and stir to evenly distribute. Some of the chocolate chips will melt, but that's normal!
Pour the oat mixture into your parchment lined square pan. Using a spoon, cup, or your hands, press the mixture into the pan until packed together. Sprinkle more chocolate chips on top, and gently press into the oat mixture.
Chill the oat bar mix in the fridge for 1 hour, or until firm enough to slice. Slice and serve!
