Dollop 1 scant teaspoon peanut butter onto half of the rounds.
Top each peanut butter–topped round with remaining banana slices, then place 1 popsicle stick through each stack, pressing down very gently to avoid peanut butter spilling out the sides.
Place on a tray and freeze at least 2 hours.
Melt chocolate and coconut oil in a heatproof bowl placed over a pot of simmering water, stirring occasionally.
Let cool slightly, then dip banana sandwiches in melted chocolate.
Place back on tray and sprinkle with chopped peanuts.
The chocolate should harden immediately. If necessary, place in freezer to set.
