Mix all ingredients, leaving coconut oil, agave and banana last. Line a baking sheet with parchment paper and shape a not too thin square. Bake in a medium oven (180°C) for approximately 20 minutes.
Remove from the oven, wait for it to cool and cut the bars with a knife. Melt the chocolate and drip over the bars. Let it dry.
Store in the fridge.
Makes: 10 bars
