Mock Butterfinger®

Line a baking sheet with parchment paper.

Spread 2 to 3 teaspoons peanut butter onto each of 24 crackers; top each with another cracker to create a "sandwich."

Arrange "sandwiches" on the prepared baking sheet. Chill in freezer until peanut butter is firm, about 1 hour.

Heat chocolate and butter together in a microwave-safe glass or ceramic bowl in 20-second intervals in a microwave oven, stirring frequently, until melted and smooth, 1 to 2 minutes.

Dip each "sandwich" in the melted chocolate mixture to coat and arrange onto the prepared baking sheet.

Chill coated sandwiches in freezer until chocolate is set, about 1 hour.
