In a medium bowl, mix the natural peanut butter, caramel sauce, and chocolate protein powder until everything is well combined. The mixture should be thick and easy to scoop.
Divide the mixture evenly between 7 silicone muffin cups. Gently press the mixture down to create an even layer.
Melt the dark chocolate chips with the coconut oil in the microwave, stirring until smooth. Drizzle the melted chocolate over each cup.
Place the cups in the freezer for at least 1 hour, or until firm. Pop one out whenever you're ready for a chocolatey treat!
