Stir the mixture then place it back in the microwave for another 30 seconds to melt completely. Whisk together until combined. Add the vanilla and mix well.
Add the Kashi GOLEAN Dark Cocoa powder and cocoa powder and mix well. Mixture should be thicker but still wet. Add the rice puffs and stir to coat completely. Stir in chocolate chips, if desired.
