To Prep: Line a large baking sheet with parchment paper or silicone baking mat and set aside.
Make the Chocolate Base - Melt the butter in a large saucepan over medium heat. Once the butter is melted, add the cocoa powder and chocolate chips, stirring until the mixture is melted and smooth.
Make the Mixture Creamy - Pour in the sweetened condensed milk and stir until just combined. Add the caramels and cook, stirring frequently, until the caramels are fully melted and the mixture is smooth again. Stir in the mini marshmallows and cook for another 2-3 minutes, until the marshmallows are melted and the mixture is completely smooth and creamy in texture.
Make it Crispy - Remove pan from heat and stir in the vanilla extract. Fold in the rice krispie cereal a little bit at a time, stirring gently until the cereal is well coated.
Form the Cookies - Drop spoonfuls of the cookie batter onto the prepared baking sheet, shaping them as needed into mounds. Allow the cookies to cool at room temperature or place the pan in the fridge for about 30 minutes, until the cookies have set and can hold their shape.
