Line 2 large rimmed baking trays with parchment paper or silicone baking mats. Set aside.

Heat the creamy peanut butter in a small, microwave-safe bowl for 30 seconds or just until the peanut butter is melted and easy to stir.

In a large mixing bowl, add the creamy peanut butter, unsalted butter, and powdered sugar. Stir until well combined and smooth.

Gently fold in the lightly crushed Rice Krispie cereal, using a rubber spatula, until all the cereal is coated with the peanut butter mixture.

Using a 1-inch cookie scoop, scoop out 28 level balls and place them onto one of the prepared baking trays. Repeat until all the rice crispy mixture has been used.

Place the baking tray into the refrigerator to chill the scoops for up to 1 hour or until firm. Once firm, lightly roll each ball in the palms of your hands to smooth the outer layer. This makes the dipped rice crispy peanut butter balls look better when dipped into the chocolate.

In a microwave-safe bowl, add the dark chocolate melting discs. Heat on high for 1 minute, then stir. Heat another one to two 30-second intervals until the dark chocolate is melted and stirred smooth. Be sure to stir between each heating interval to ensure that you do not burn your dark chocolate, or it may seize up.

Using a fork, carefully dip a rice crispy peanut butter ball into the melted dark chocolate and roll around to completely cover it in the dark chocolate.

Using the fork, lift the dark chocolate-coated rice crispy peanut butter ball out of the bowl and gently tap the fork on the side of the bowl to allow any excess dark chocolate to drip back into the bowl. Using a second fork or toothpick, very carefully slide the dark chocolate dipped rice crispy peanut butter ball onto the second prepared baking tray. Repeat until all the rice crispy peanut butter balls have been dipped into the dark chocolate.

To create a decorative drizzle on the tops of each dark chocolate-coated rice crispy peanut butter ball, use a spoon to drizzle some of the remaining melted dark chocolate in an ornamental pattern over the coated rice crispy peanut butter balls once the dipped balls have started to harden and set. This is a great way to cover any flaws from dipping and to use up any excess melted dark chocolate.

Place the tray of dark-coated rice crispy balls back into the refrigerator for 15 minutes to set and harden the dark chocolate coating. Once the dark chocolate coating has fully hardened, you can remove the rice crispy peanut butter balls and place them onto a serving platter.
