Slice one banana and place in a single layer on a tray lined with non-stick baking paper. Freeze for 2 hours, or until firm.
Meanwhile, preheat the oven to 180 degrees (160 degrees fan-forced). Line a large baking tray with non-stick baking paper.
Mash the remaining banana in a bowl. Then, stir in the oats, cinnamon, maple syrup and choc chips until well combined.
Spoon 1 tablespoon of the mixture onto the lined tray and shape it into a neat 5cm round cookie. Repeat for the remaining, to make 12 cookies in total.
Bake the cookies for 18-20 minutes until cooked and golden. Cool the cookies completely on the tray.
Blend the frozen banana in a small food processor until completely smooth and creamy. Sandwich the banana ice cream between two cookies and serve!
Notes
These cookies don’t spread during baking so it’s important to shape them into nice flat rounds so they cook evenly.
The 5cm cookies will have a chewy centre. If you prefer a crisper cookie, then flatten it into 7cm rounds and bake for 16-18 minutes, or until golden and crisp.
