Line a baking tray with baking paper.
Insert a popsicle stick or skewer into the cut side of each banana half and place it onto the prepared tray. Freeze for 30 minutes or until firm.
Meanwhile, mix peanut butter powder with cinnamon and 2 tablespoons of water in a small bowl until smooth and combined.
Spoon the mixture into a reusable piping bag with a nozzle and set aside.
Microwave white chocolate in a small microwave-safe bowl on High (100%) in 15-second increments, stirring each time until completely melted.
Spoon melted white chocolate into a second piping bag with a nozzle.
Remove bananas from the freezer and drizzle with melted white chocolate and peanut butter mixture, leaving a small space to place the eyes.
To make the eyes, pipe a dot of melted white chocolate onto each milk chocolate chip.
Place onto the reserved space on the banana.
Place mummies in the fridge for 30 minutes or until set. Serve.
If you don’t have a reusable piping bag, you can purchase disposable plastic piping bags from major supermarkets. Just be sure to rinse and recycle it at your local major grocery store. You can find soft plastic recycling bins by the checkouts. Be careful not to overheat the white chocolate, as it will go hard.
