I love an on-the-go breakfast idea and these porridge bars have been such a hit with my kids. They work well as a snack too, and are very easy to put together. They take a little time on the cooking front, but next to no time to prep, and are well worth it. They freeze well so are perfect for batch-cooking.
Based on 12 servings, adjust as needed.
Preheat the oven to 180°C/160°C fan and line a 20cm square shallow baking tin with non-stick baking paper. Mix all the ingredients together (except the seeds), then mash it well with a fork to completely break up the bananas. Once everything is well mixed, scoop it into the baking tin and level the top. Sprinkle the mixed seeds on top (leave them off or grind them if serving to babies and young children).
Bake for 50-55 minutes, until the top is golden and crisp. Once cooked, remove from the tin using the baking paper and leave to cool on a rack until either warm or cooled to room temperature
Slice into 24 small squares or 12 larger bars to serve. The bars will be kept in an airtight container for up to 3 days or can be wrapped in clingfilm/beeswax and frozen individually, then defrosted on the counter overnight, ready for the morning. You can also reheat them uncovered in a microwave for 20 seconds if you'd like them warm.
