Line a 9x13 pan with parchment paper.
In a microwave-safe bowl, melt half of the dark chocolate melting wafers (10-ounces) according to package instructions. Spread into the prepared pan and then tap the pan on the counter a few times to help the chocolate smooth out. Place in the fridge for 5-10 minutes, or until hardened.
In a small bowl, melt peanut butter (½ cup) in the microwave for 15-30 seconds. You want it thin and pourable but not too hot, or else it will melt your chocolate.
Remove the chocolate pan from the fridge and pour the melted peanut butter on top. Use a spatula to spread it until the chocolate is covered.
Break 3-4 waffle cones into pieces and press on top of the peanut butter layer. I like to face the "waffle" texture on top to resemble the Nutty Buddys.
Melt the remaining dark chocolate melting wafers (10-ounces) according to package instructions.
Pour chocolate into a piping bag or gallon-sized ziploc bag and drizzle over top the waffle cone layer, then use a spatula to fill in any gaps. Tap the pan on the counter to smooth out the chocolate.Note: By using a piping bag, you avoid shifting the waffle cones around too much. Immediately add sprinkles if desired and another 3-4 broken waffle cone pieces. Place in fridge to harden, then break apart!
Store in an airtight container for up to 1 week.
