Start by greasing a 9x13 inch pan and set it aside for later.

In a large saucepan, melt the butter over medium-low heat. Keep an eye on it to prevent burning! Stir occasionally for even melting.

Once the butter is melted, stir in the mini marshmallows until completely melted and smooth, about 3-5 minutes.

Pour in the Rice Krispie cereal and mix well until all the cereal is coated with the marshmallow mixture. Use a spatula for folding.

Transfer the mixture into the prepared pan and press it down evenly with a spatula or your hands. Make sure it's compact for better slicing later.

Sprinkle the salted peanuts evenly over the top of the Rice Krispie layer for added crunch.

In a medium saucepan, combine the unwrapped caramels and heavy cream. Heat over medium heat, stirring continuously until smooth, about 5-7 minutes.

Pour the caramel mixture over the peanut layer, spreading it out evenly. Allow it to set slightly before moving on.

Melt the chocolate chips in the microwave in 30-second increments, stirring in between until smooth, about 1-2 minutes total. Pour the chocolate over the caramel layer and spread it evenly.

Allow the chocolate to set before slicing into squares. For easier slicing, let the treats cool completely at room temperature. Enjoy your delicious treats!
