Prepare a loaf pan by spraying lightly with cooking oil and lining with parchment paper so the paper sticks to the pan. Then lightly spray the parchment paper to prepare for the treats.
Unwrap tootsie rolls and cut each mini tootsie roll in half. Set aside 5-8 pieces if you want to press them into the tops at the end.
Melt 3 Tbsp butter in a medium pot. Add ½ tsp salt and cook the butter until toasty over medium heat.
Remove from the heat and add marshmallows. Stir constantly until marshmallows begin melting. Once marshmallows have started to dissolve, add the pot back onto low heat and continue stirring until fully melted.
Crush 1½ cups of Cocoa Rice Krispies. I just roughly crush them in my hand as I add them to the melted marshmallows.
Stir so everything is coated. Add the remaining ¼ tsp salt, remaining 1½ cup Rice Krispies, and the tootsie rolls and mix until everything is coated evenly.
Don’t use your hands, the marshmallow may be hot! Using another piece of parchment paper, or the flat bottom of a glass, press lightly into the corners and flatten the treats. You can also give a light dusting of cooking spray to your surface to help keep it from sticking. Press the reserved tootsie roll halves into the top if desired.
Allow treats to set for at least an hour before cutting and serving.
