Line a baking sheet with waxed paper.

Put the chocolate chips in a small, heavy saucepan. Put the pan on the stove and switch on the heat to low. Stir constantly until the chocolate is melted and smooth. Remove from heat and set aside.

Peel the banana. Put on a cutting board and cut into 4 equal pieces.

Place the peanuts in a small bowl. Break the Kit Kat® into four bars. Cut each bar in half and set aside.

Dip 1 banana piece in the melted chocolate. Dip just the top of the banana piece into the peanuts.

Place the banana piece nut side up on the lined baking sheet. Press 2 Kit Kat® pieces along either side of the banana.

Repeat steps 5 and 6 with the remaining banana pieces.

Place the baking sheet in the freezer until chocolate has hardened, about 15 minutes. Serve straight from the freezer.
