  • ▢1 ½ cup / 150g almond flour or ground almonds
  • ▢½ cup / 120g mashed banana 2 small or 1 large, very ripe
  • ▢3 eggs large
  • ▢2 tbsp butter, melted
  • ▢¼ cup / 50g granulated erythritol (So Nourished)
  • ▢2 tsp cinnamon
  • ▢1 tsp baking powder
  • ▢¼ cup / 30g walnuts, crushed


  • Preheat the ove to 180 Celsius / 356 Fahrenheit.
  • Using an electric mixer, beat the eggs together with the mashed banana and melted butter until smooth.
  • In another bowl, stir together the dry ingredients – almond flour, erythritol or sweetener of choice, cinnamon and baking powder. Add to the bowl with the egg/banana/butter mix and blend until well-combined.
  • Last, stir in the crushed walnuts, reserving some to sprinkle over the top of the bread.
  • Line a small (7 x 3.5 inch / 1 lb) loaf tin with parchment paper and fill in the dough. Sprinkle the leftover walnuts on the top.
  • Bake for circa 40 minutes or until a knife inserted comes out clean. Check the cake at minute 30. If the top is already brown enough, loosely place aluminium foil over it so it does not burn.
  • Let the banana bread cool completely before slicing

The walnuts are optional. You can use any other nuts in this recipe or even replace them with sugar free chocolate chips. 

A pinch of nutmeg would also work well. 

If you only have a regular size 9 x 5 inch loaf tin, you can double the recipe. In this case, increase the baking time to about 55-60 minutes. 

One slice of keto banana bread weighs circa 60 grams.
