In a small food processor, pulverize the banana chips until they reach a powder like consistency. Transfer to a bowl and add in the Cheerios, and hemp hearts.
In a small sauce pot, heat the honey and sunflower seed butter until its gently simmering and bubbling, stirring constantly. Remove from the heat and transfer to the bowl with the Cheerios. Stir until all of the cereal is well coated and mixed.
At this point you can add in the sunflower seeds if using. Take a small handful and stuff it into a muffin mold. Repeat with the remaining cereal. Allow to cool completely.
Once cool, carefully remove from the muffin mold and drizzle with chocolate, if using.
