Prep: Coat a large cookie sheet with non-stick cooking spray, or line it with parchment paper or a silicone baking mat.

Melt: Place the marshmallows, peanut butter (or sunflower seed butter), and honey in a large saucepan or skillet. Cook over medium-low heat, stirring constantly.

Mix: Once the marshmallows are completely melted, remove the pan from the heat. Immediately stir in the Honey Nut Cheerios until the cereal is evenly coated with the sticky mixture.

Shape: Grease a 1-cup measuring cup (or simply grease your hands) to portion out the mixture. Roll the portions into balls and space them out on your prepared cookie sheet.

Set: Place the baking sheet in the refrigerator and let the Cheerio balls chill for at least 45 minutes so they can set before serving.
