In a medium bowl, combine peanut butter, maple syrup, vanilla, 3 Tbsp powdered peanut butter, and salt. Stir well.
You want it the consistency of play dough. If it is still too sticky, add another Tbsp of powdered peanut butter and stir.
Add the rice cereal and stir carefully. You want to evenly incorporate them but not completely crush them.
Roll about 1 1/2 Tbsp of dough into a ball. Repeat until you have 16 balls or used up all the dough.
Place dough balls in the freezer for 20-30 minutes. (This makes dipping them in chocolate easier.)
In a microwave safe bowl, break chocolate into pieces. Microwave for 30-90 seconds, stirring every 15 seconds until melted. Careful not to overheat the chocolate.
Remove balls from the freezer. Stick a toothpick into the ball and dip into the chocolate. Use another toothpick to ease the ball off the original toothpick onto parchment or wax paper. Repeat for each ball. Allow chocolate to harden and enjoy.
