Preheat the oven to 180‘C / Gas 4/ 160’C Fan. Line an 8-inch/20cm square baking tin with baking paper and set aside.
Peel the bananas and mash them up in a bowl, using a fork.
To a large saucepan, add the butter, sugar, syrup and peanut butter. Heat over a low heat, stirring constantly, until the butter has melted. Remove from the heat.
Add the mashed banana and mix until combined. Then add the oats and mix again until there are no dry patches.
Pour the mixture into the lined baking tray and use a spoon to press the mixture down as compact as possible, and right into the corners and edges of the pan.
Bake for 20 minutes. Once baked, remove from the oven and onto a cooling rack. Cool to room temperature before cutting into 8 bars or 16 squares.
Notes
Weighing Scales vs Cups: You can toggle this recipe card to convert the ingredients into cups. However, I always recommend using weighing scales – these are cheap to buy and much more accurate. And in gluten free baking, a tiny variation can make a huge difference!
