Ingredients:

  • 3 cups (375g) all-purpose flour
  • 3/4 cup (150g) coconut sugar
  • 1/2 cup (115g) unsalted butter, softened
  • 1/4 cup (60ml) neutral oil
  • 3 large eggs, room temperature
  • 1 cup (240ml) mashed overripe bananas
  • 1/2 cup (120ml) low-fat buttermilk
  • 1/2 tsp (2.5g) baking soda
  • 2 tsp (10g) baking powder
  • 1/2 tsp (3g) salt
  • 1 tsp (5ml) pure vanilla extract
  • 4 oz (115g) low-fat cream cheese, softened
  • 2 tbsp (30g) unsalted butter, softened
  • 1 cup (120g) powdered sugar
  • 1 tsp (5ml) lemon juice

Instructions:

  1. Preheat oven to 325°F (160°C). Grease a 9x5 inch loaf pan and line the bottom with parchment paper.
  2. Mash the bananas in a small bowl until completely smooth with no large lumps.
  3. Whisk together the all-purpose flour, baking soda, baking powder, and salt in a medium bowl; set aside.
  4. In a large bowl, cream together the 115g softened butter, neutral oil, and coconut sugar using a hand mixer on medium speed until light and airy.
  5. Add the eggs one at a time, beating well after each addition, then stir in the vanilla extract.
  6. Gradually add the flour mixture in three parts, alternating with the low-fat buttermilk, beginning and ending with the flour.
  7. Gently fold in the mashed bananas using a spatula until just combined.
  8. Pour the batter into the prepared loaf pan and smooth the top.
  9. Bake for 75 to 90 minutes until a toothpick inserted into the center comes out clean or with just a few moist crumbs.
  10. Cool the cake in the pan for 15 minutes, then transfer to a wire rack to cool completely.
  11. Whip together the low-fat cream cheese, 30g softened butter, powdered sugar, and lemon juice until smooth.
  12. Spread the frosting evenly over the completely cooled cake.
