Prep 12 mini muffin liners: Place them in a muffin tin to create a convenient mold for your cups.
Process 8 oz unsweetened coconut until creamy: Use a food processor to blend the coconut until it becomes a smooth paste, about 3-5 minutes. Scrape down the sides as needed. This creates the main body of your cups.
Blend in sweetener and 2-3 tablespoons defrosted pitaya smoothie packet: Add 1/2-1 tablespoon agave, honey, or maple syrup to the food processor and mix until combined. The mixture should be slightly sweet and well-blended.
Mix in 1-2 tablespoons melted coconut oil: Adding coconut oil will help create a smooth texture. Process until fully combined and set aside.
Fill each cup with the pitaya coconut butter mixture: Spoon about 1 tablespoon of the coconut mixture into each muffin liner, pressing down slightly to form a layer.
Add 1/4-1/3 cup of your choice nut butter: Place a small dollop of your chosen nut butter on top of the coconut layer in each cup, ensuring it is centered.
Top again with coconut butter: Add another tablespoon of the pitaya coconut mixture to seal in the nut butter, ensuring it is fully covered.
Chill for 10 minutes: Place the muffin tin in the refrigerator to let your cups set, making them easier to remove later.
