Chop the dark chocolate into small, even pieces and place them in a heatproof bowl.
In a small saucepan, gently heat the peanut butter and honey over low heat, stirring until the mixture is smooth and fragrant, about 2 minutes.
Pour the warm peanut butter mixture over the chopped chocolate and let sit for 2 minutes, allowing the chocolate to melt slightly.
Gently stir the mixture until glossy and smooth, ensuring all the chocolate melts evenly into the peanut butter blend.
Transfer the mixture to the refrigerator and chill for 1 to 2 hours until it firms up but remains pliable.
Line a tray with parchment paper. Using a small scoop or spoon, portion out the chilled mixture into 1-inch balls and place them on the tray.
Melt additional chocolate if needed. Using two forks, dip each ball into the melted chocolate, turning to coat evenly.
Place the coated truffles back on the parchment-lined tray and chill for 30 minutes to set the chocolate coating.
Optionally, roll the truffles in crushed nuts or sprinkles before the chocolate hardens for added texture and decoration.
Once the chocolate coating is firm, transfer the truffles to an airtight container and store in the fridge. Let sit at room temperature for 10 minutes before serving for the best texture.
