Line an 8×8 pan with parchment paper. In a large bowl, add the brown rice crisps.
In a medium bowl, add the almond butter and maple syrup. Heat in the microwave for 30 seconds. Stir until smooth and combined. Add the vanilla extract and salt. Stir until well combined.
Pour mixture over the rice crispy cereal. Stir with a spatula until everything is well combined and evenly coated. Spread mixture into the lined pan and evenly press down into the pan. Place in the freezer while you prep the chocolate topping.
In a small bowl, add the chocolate chips and melt in the microwave in 30 second intervals, stirring in between each interval until chocolate is completely melted. Mine took 1 minute and 20 seconds. You can also melt it in a small sauce pan over very low heat, stirring continuously. Pour chocolate over the rice crispy. Spread chocolate evenly over the top. Place in the freezer for 45-60 minutes to set. Sprinkle bars with course sea salt and slice into bars. Enjoy!
