1. Get out a piece of parchment paper.
2. In a medium saucepan over medium heat, mix everything except for the cereal until well combined.
3. Carefully stir in the cereal. If the mixture isn't sticking together well, use your hands to mix together.
4. Place the mixture on the parchment paper and pat it into your desired shape and thickness. I made mine in a rectangle which was about 1" thick. Make sure to firmly pat the mixture down so that it'll hold together.
5. Refrigerate the bars for about 30 minutes and then cut and serve.
6. Cover and store leftovers for up to 5 days.
