Grease a two quart dish such as a 7x11 or 8x8 pan with butter and then set it aside for now.
In a tall stock pot, melt the vegan butter over medium heat.
Then, to that pot add the brown rice syrup, maple syrup, vanilla, and salt, and stir to combine.
Add the crispy rice cereal and stir with a long handled spoon until the cereal is evenly coated.
Pour this mixture into your prepared pan.
Using the back of a spatula, press down VERY FIRMLY across the surface to make it compacted and evenly flat. If you find that the crispy treats are sticking to your spatula, grease it and try again.
Immediately add the chocolate chips to the surface and press down VERY FIRMLY using that spatula once again.
Allow the crispy treats to set and cool completely before cutting into them, at least 2 hours. Cut into bars using a very sharp knife. Enjoy!
