01 - Line a standard 12-cup muffin tin with paper liners and set aside.
02 - Combine chocolate and coconut oil in a heatproof bowl. Melt gently over a double boiler or microwave in 30-second bursts, stirring until smooth and fully combined.
03 - Spoon approximately 1 teaspoon of melted chocolate into each lined cup. Tilt the tin to coat the bottom evenly. Place in freezer for 10 minutes until set.
04 - While chocolate sets, combine peanut butter, powdered sugar, softened butter, vanilla extract, and salt in a mixing bowl. Beat until smooth and thickened.
05 - Roll the peanut butter mixture into 12 equal small discs. Place one disc atop each chocolate base, pressing gently to flatten slightly.
06 - Spoon remaining melted chocolate over each peanut butter disc, ensuring complete coverage. Tap the tin gently on the counter to level the surface and remove air bubbles.
07 - Refrigerate for 30 minutes or until completely firm. Remove from liners and serve chilled or at room temperature.
