Gluten and Dairy Free Banana Buckwheat Slice with Peaches

Super easy tray bake from the simple and short list of ingredients, prepared, baked and ready in less than an hour. The batter is quite runny, but still holds slices of canned peaches upright during baking. The bake has a soft springy texture with a gentle taste of banana. This bake can take any spices or spice mixes to make the taste more distinct, for me it was a trial run for the batter, based on bananas blended with lemon juice and buckwheat flour. Banana buckwheat slice can be baked in all shapes and sizes, but a tray bake is the fastest and most flexible option.


The batter is gluten and dairy free, and very low on added sugar, which can be completely omitted for those who want to cut added sugars out of their diet.



  • 250g diced bananas (3 small bananas)
  • 30ml lemon juice
  • 60-70g sugar (if sugar is not used, do not add lemon juice)
  • 2 large eggs
  • 5g baking powder
  • 1 tea spoon vanilla paste or extract (I used paste)
  • 120g buckwheat flour (I used Ceres Organics)
  • butter or coconut oil to grease the pan


  • canned sliced peaches (SPC in mango puree taste the best)


  • grease baking tray 20cm x 30cm (18×28 inner size) with butter or coconut oil for dairy free bake
  • drain canned sliced peaches
  • mix buckwheat flour and baking powder
  • blend diced bananas with lemon juice and vanilla paste/extract with a stick blender
  • whisk eggs with sugar until pale and triple in volume
  • add blended bananas to eggs, mix and combine fully with a whisk
  • add dry ingredients, mix until fully combined to a runny batter with no lumps
  • pour the batter into prepared greased baking tray
  • insert peach slices
  • bake for 35 min in preheated to 165-170C fan forced oven
  • let the bake rest in a tray for 5-7 min
  • turn it over first on a wire rack, second time on a serving board/platter
  • let the bake rest and cool a bit
  • the bake can be sliced while still warm


To get a neat cut use serrated bread knife.


I have left the bake for too long in a tray and its bottom became too soft for my liking. To crisp it up I have returned the turned over bake to a switched off oven, that is why wire rack prints can be seen on the surface of the bake.

    1. Fresh peaches will give a lot of juices, I would go for a thicker batter if fresh juice fruits – peaces or apricots are used, but pears or apples would be fine even for a runny batter.
