Preheat oven to 350F and grease a 9-inch square silicone baking dish with coconut oil (or line with parchment paper),
In a medium sized bowl, whisk together the ground chia seeds and water. Let it sit in the fridge for 10-15 minutes to thicken.
Add in the peanut butter, cocoa powder, coconut sugar, maple syrup, coconut oil, vanilla extract, baking soda, and salt. Mix well.
Fold in the chocolate chips.
Scoop the dough out and press down into the pan to flatten. Bake for 20 minutes. Let the brownies cool before cutting otherwise they will fall apart easily. Enjoy!
