Method:
1. Preheat a fan oven to 175°C and line a shallow tray/tin. Mash banana until smooth and prepare/drain cherries as required.
2. Combine wholemeal flour, plain flour, cocoa, KWERKY, baking powder and bicarbonate thoroughly so cocoa and raising agents are evenly dispersed.
3. Whisk egg, water, oil and sugar, then mix in the banana. Fold the wet mixture into the dry ingredients only until combined.
4. Fold through the cherries carefully. Spread into the prepared tray to an even depth and level the surface.
5. Bake for 35 minutes at 175°C fan, until set through the centre and lightly coloured. Confirm doneness with a clean skewer/probe before removal.
6. Cool completely before cutting into 10 equal portions. Apply site cooling, storage, allergen and date-coding procedures.
