If using an 8x8 cake pan, first line it with foil going all the way up the sides and spray with cooking spray. If you are using a mold have it nearby.
In a large bowl mix together the 2 cups of puffed rice and 1 tablespoon of sesame seeds.
Then in a small sauce pan add in ½ cup of honey, 2 tablespoons of butter, 2 tablespoons of cashew butter and a pinch of salt. Mix together until combined and place on the stove on medium heat.
Bring up to a boil and then turn the heat down to low.
Then simmer for 5 minutes until the mixture thickens and looks like caramel.
While the mixture is still hot pour it all over the rice and sesame mixture and mix well.
Transfer to a mold an 8x8 square pan. Spread in a thin layer and smooth out the top. Press down with your hands or offset spatula to make sure the rice is a bit compressed.
Leave to cool in the refrigerator for 30 minutes and then unmold or cut into small peices (if using the 8x8 pan).
