01 - Line a 12-cup mini muffin tin with paper liners, ensuring each cup is ready for filling.
02 - Place chocolate chips and coconut oil in a heatproof bowl. Microwave in 30-second intervals, stirring between each, until completely smooth and melted.
03 - Spoon approximately 1 teaspoon of melted chocolate into each liner. Tilt the tin gently to coat bottoms evenly. Freeze for 10 minutes until firm.
04 - Combine creamy peanut butter, melted butter, powdered sugar, and sea salt in a mixing bowl. Beat until smooth and fully incorporated.
05 - Drop about 1 heaping teaspoon of peanut butter mixture onto each set chocolate base. Gently flatten to create an even layer, leaving a small border around edges.
06 - Cover each cup with remaining melted chocolate, using 1 to 1.5 teaspoons per cup. Smooth tops to ensure peanut butter filling is completely covered.
07 - Refrigerate for at least 30 minutes or until completely firm. Cups should hold shape when touched.
08 - Remove paper liners carefully. Transfer to an airtight container and refrigerate until ready to serve.
