Cut the banana in half.
Using a butter knife, spread almond butter on both sides and place on a parchment-lined baking sheet.
Add a saucepan of water to the stove and bring to a boil. Add a glass (or other heat resistant bowl) on top of the boiling water and add chocolate chips, stirring occasionally.
Stir until all of the chocolate chips are melted.
Sprinkle on the nuts to the almond butter and banana. Drizzle with melted chocolate.
Place the frozen bananas in the freezer for at least an hour and enjoy.
