Line a couple of plates with parchment paper (you'll need these for chilling the pops), then peel several Granny Smith apples. Use a melon baller to scoop out mini apple "balls." Pat them with a paper towel, getting them as dry as possible. Insert a lollipop stick and get ready to dip! (Be sure to pat dry again before you dunk.)
Microwave together 1/2 cup peanut butter chips and 1 Tbs. butter at 50 percent power for 30-second intervals, stirring between each, until just melted and smooth. Dip apples. Chill for 10 minutes. Dip apples in melted chocolate. Chill for 10 minutes more.
