In a small sauce pan, combine the peanut butter, maple syrup, and coconut oil over medium heat. Whisk together until thick and creamy, for about 2-3 minutes.
Turn the fire off and whisk in the vanilla extract.
Let the mixture cool while you combine the dry ingredients.
In a large bowl, combine the oats, cereal, chia seeds, salt, and 1/4 cup of the chocolate chips.
Pour the wet ingredients into the dry bowl, and toss together until evenly incorporated.
Line a medium sized baking dish, about 10u0022 by 7u0022, with parchment paper. Flatten the mixture into the pan and even out the top.
Let the mixture sit for 1 minute or so to cool, then pour the rest of the chocolate chips over the top and flatten them into the bars with the back of a cup or with your hands.
Refrigerate the bars for at least 2 hours. Once hard, slice into 12 squares, or 16 bars.
Keep refrigerated in an airtight container for up to 3 weeks!
