This delicious, moorish cake made with buckwheat flour and ground almonds is the perfect mid-afternoon treat! It’s effortlessly gluten free, low FODMAP refined sugar free and vegan without missing out on flavour. Due to the natural sweetness of the bananas you don’t need to add much coconut sugar to the recipe.
