Ingredients
  

Gluten-free Banana Cake

  • 400 g Banana (1.5 cups)
  • 190 g Yogurt (¾ cup)
  • 1 tbsp Lemon Juice or Vinegar
  • 60 g Liquid Sweetener (3 tbsp)
  • 225 g Oat Flour (2 ¼ cups)
  • 1 tsp Bicarbonate of Soda
  • ½ tsp Salt

Healthy Chocolate Frosting

Instructions
 

  • Preheat your oven to 350°F (175°C) and lightly grease or line a 9-inch springform cake tin with parchment paper.
  • If using whole oats, blend into a fine powder for oat flour.
  • In a large mixing bowl, mash bananas until smooth. Add yogurt, honey, and vinegar, and whisk until fully combined.
  • Add oat flour, bicarbonate of soda, and salt to the wet mixture. Gently fold until just combined.
  • Pour the batter into the prepared cake tin, smooth the top, and bake for 25–30 minutes, or until a toothpick inserted in the center comes out with a few moist crumbs.
  • In a small bowl, mix yogurt, cocoa powder, and honey until smooth and creamy. Adjust thickness if needed by adding more yogurt or cocoa powder.
  • Once the cake has cooled, spread the chocolate frosting over the top and sprinkle with chopped walnuts, if desired.
  • Slice and enjoy!

Notes

TIPS & NOTES:
  • For the best flavor and natural sweetness, use very ripe bananas. If your bananas aren’t ripe enough, place them in a warm oven until they soften and turn brown.
  • To make your own oat flour, blend gluten-free oats into a fine powder, then sift for a smoother texture.
  • For a thicker frosting, add more cocoa powder, or chill the frosting for 10–15 minutes before spreading.
  • For a dairy-free option, use a plant-based yogurt like coconut or almond.
  • To make the cake vegan, replace honey with maple syrup and use dairy-free yogurt.
 
 
MEASUREMENTS:
 
I always recommend using a kitchen weighing scale and using weighted measurements. This will result in a more accurate process and your cake will come out perfectly.
