Sugar-free banana cake

Simple sugar-free banana cake for toddlers and babies

Looking for a healthy birthday cake? This sugar-free banana cake is naturally fruit sweetened. As is, it tastes like a banoffee pie, however, it can also be flavoured with chocolate, vanilla or strawberry. See the section above for more information.



Banana Sweetened Cake

  • 1 3/4 cup of flour (I use my gluten-free blend)
  • 1/2 cup of buttermilk (milk kefir or yogurt)
  • 1/3 cup butter, melted
  • 4 very ripe bananas
  • 3 eggs
  • 1 tsp vanilla
  • 1 tsp baking powder
  • 1/2 tsp baking soda
  • 1/4 tsp salt

Date Sweetened Caramel Frosting

  • 8 large Medjool dates, pits removed
  • 1/2 cup water
  • 1 cup whipping cream


Banana Cake

  1. Preheat the oven to 350 F.
  2. Mash the bananas in a large mixing bowl until relatively smooth.
  3. Mix in the melted butter, then the eggs, buttermilk and vanilla.
  4. Add in the flour, baking powder, baking soda and salt.
  5. Stir until everything is evenly mixed. 
  6. Pour into two 6″ cake pans.
  7. If you are making a gluten-free cake, the texture will improve if the batter is allowed to rest for 30 minutes prior to baking. Otherwise, bake right away.
  8. Bake at 350 F for 25-35 min (until a toothpick comes out clean).
  9. Allow the cake to cool before frosting.

Date Frosting

  1. Place the dates and the water in a blender. Be sure to remove the pits!
  2. Pulse until the dates have turned into a smooth paste. If you aren’t using Medjool dates, then you may need to add more water to get the dates to blend nicely.
  3. Once the dates are fully pureed, add the whipping cream and continue to blend until you have a nice thick, whipped frosting.
  4. The frosting needs to be kept cool. I recommend either frosting the cake right before serving or storing the frosted cake in the fridge.


  • Instead of making a 6″ layer cake, this batter will also make an 8″ square or 18 cupcakes.
  • Why not make a super healthy cake by serving it with a probiotic frosting?! To make the frosting probiotic use cultured whipping cream.
