1½cupsassorted Reese's cups, mini-size or roughly chopped miniature or regular size cups
½cupsemi-sweet chocolate chipsoptional
1teaspoonrefined coconut oil or vegetable oiloptional
Line a baking sheet with parchment and set aside. (Feel free to use foil, if you'd prefer. Just don't forget to grease the foil very well with butter!)
Melt the butter in a large pot, over medium heat. Add the marshmallows and stir until almost melted. Add the peanut butter and stir until smooth.
Remove from the heat and stir in cereal until well coated. (If desired, add the additional marshmallows now.) Gently stir in the peanut butter cups, until mixed throughout.
Scoop the sticky mixture onto the prepared pan. Lightly wet your hands (or butter them) and gently press the cereal out across the pan, taking care not to press too hard and compact them. Let cool for a few minutes before slicing.
Optional Chocolate Topping
Combine the chocolate chips and oil in a small glass bowl. Microwave for one minute, stir. Microwave an additional 30 seconds, only as needed. When the chips are mostly melted, remove from the microwave and stir until smooth.
Drizzle the rice krispie treats very lightly with the melted chocolate, if desired. Store in an airtight container for several days. Enjoy!
For an especially gooey treat, you can add additional marshmallows right at the end, just before pressing the mixture into the pan. I like the rice krispy treats both ways, but for the most part, I add those extra marshmallows every time.
