Line a 9 x 13 cake pan with parchment paper and set aside.
In a large soup pot, add the Butter and melt on low heat.
Add marshmallows and stir until melted.
Turn the heat off, stir in the Caramel Bits and the Cereal
Immediately transfer the Cereal mixture into the pan. Using the back of a spatula press the mixture flat in the pan going all the way to the edges, nice and even. Work fast here, to get the right shape!
Let the bars cool down on the counter, uncovered.
In the meantime, melt your choosen chocolate on stovetop.
Use the parchment to lift the bars out of the pan. Cut them into small-size Bars, and place them on a cookie cooling rack. Drizzle your bars with chocolate, sprinkle nuts or even chocolate sprinkles on top.
Let them set for about 5 minutes. Ready to eat, ready to enjoy!
