Add the coconut oil, cacao powder, and sweetener to a small saucepan placed over medium-low heat.
Once the mixture is barely melted, remove from heat and stir in the nut butter and coffee grounds.
Line a mini-muffin tray with paper liners. Pour the peanut butter cup mixture into the cups, filling them ¾ the way full.
Freeze for 15-20 minutes or until hardened. Once frozen, remove from tin and place in freezer bags. Store in the freezer. Enjoy!
Notes
*Use 2 droppersful liquid stevia if on Fast Track.** For "Double-Shot" Study Cups, you can add 1-2 rounded teaspoons of finely ground espresso or coffee grounds. This will alter the flavor of your candy, making it more bitter. If desired, add more sweetener!
