In a large, microwaveable bowl, add unsweetened chocolate chips, maple syrup, sun butter, coconut oil, and vanilla. Melt in 30 second intervals using microwave until completely melted.
In the large bowl, add rice Chex cereal and gently coat with chocolate mixture.
Once cereal is coated in chocolate, add 1 cup almond flour to the bowl and slowly and gently cover everything in the powder. If you wish to have a sweeter treat, use powdered coconut sugar (or a combo of that with almond flour). Add more almond flour if needed to ensure all the melted chocolate is covered.
Refrigerate until chocolate firms up. Serve and snack on!
