Line a small baking sheet with 24 mini cupcake liners (candy liners).
Add chocolate chips, white chocolate chips, and peanut butter to a microwave-safe bowl.
Heat in 30-second increments, stirring in between, until melted and smooth.
Spoon the chocolate mixture into the liners 1/2- 2/3 full.
Chill for 30 minutes.

Notes
The meltaways will harden and the liners will peel off easily when ready to eat. Because they have peanut butter in them, the warmth of your fingers will cause them to soften the more you handle them. They will also soften slightly if left on the counter in a warm kitchen.They are best stored in the refrigerator until ready to serve.
