Preheat oven to 350 degrees. Line a baking sheet or sheet pan with parchment paper.
In a large microwavable bowl add cereal & set aside.
In small microwavable bowl add in brown sugar, butter and corn syrup. Microwave for 1 minute, then stir until smooth, then heat for another minute. Immediately stir in baking soda until it has complete dissolved.
Pour caramel mixture over cereal in the large bowl, mix until cereal is evenly coated. Place back in the microwave and heat for 1 minute, remove bowl and gently stir cereal once again, then reheat for another minute, remove from microwave and stir once more.
Then spread the cereal mixture on the prepared baking sheet. Bake for 5-8 minutes. Once you remove the mix from the oven immediately sprinkle with toasted coconut, set aside.
In a small microwavable bowl, add caramel pieces and milk, heat in the microwave for 1 minute, stir then heat again for another 30 seconds to a minute until caramel is completely melted and smooth. Use a spoon to drizzle caramel mixture over snack mix, toss the snack mix with the caramel so that the coconut sticks to the cereal. Top with chopped SNICKERS.
In a small microwavable bowl, heat the dark melting chocolate for 1 minute, stir and then reheat for another 30 seconds or until chocolate is completely smooth.
Using a spoon drizzle the chocolate over the snack mix, toss gently, to make sure SNICKERS and coconut are stuck to the cereal.
Set aside and let it cool for 5-10 minutes, then break into pieces and serve.
