Add the peanut butter, coconut oil, honey, vanilla extract, cinnamon, and salt to a small saucepan. Heat the peanut butter mixture over medium low heat until everything is warm and melted together.
Add the gluten free brown rice cereal to a large mixing bowl and then pour the peanut butter mixture over the cereal. Stir until the peanut butter and cereal are well combined.
Pour the cereal mixture into a prepared 8×8 pan. Use a spatula or your finger tips to press the bars evenly into the pan.
Add the chocolate chips and one tablespoon of coconut oil to the same small saucepan you used to make the peanut butter mixture. Heat the chocolate over medium heat until melted and smooth. Pour the melted chocolate over the peanut butter treats and then use a spatula or knife to spread the chocolate into an even layer. Let the chocolate cool for around forty-five minutes until completely set.
Once the chocolate has set, cut the treats into squares, top with sea salt, and enjoy!
