Combine the coconut oil and brown rice syrup in a saucepan over medium heat, and bring the mixture to a rolling boil. Boil for one minute, then remove from the heat and stir in the vanilla extract and salt. Pour the cereal into a large mixing bowl and stir in the boiled syrup mixture until the cereal is well-coated.
Line a 9-inch baking sheet with parchment paper to prevent sticking, then spread the coated cereal in the pan. Use an additional piece of parchment paper over the top of the cereal, to keep your hands from getting sticky, then press HARD to pack the cereal tightly into the bottom of the pan. The harder you press, the better.
Place the bars into the freezer to cool for 45 minutes, then remove the pan and bring the bars to room temperature. Slice and serve!
Store any leftover bars in a sealed container in the fridge for best shelf life.
