Pro Tips

  • If your bananas aren’t ripe you can bake them in an oven preheated to 170 degrees Celsius (350 degrees Fahrenheit) for 7 min.
  • Don’t have buttermilk? No problem make it at home by adding 1 1/2 tbsp. vinegar for every one cup of milk and let it sit for 5 min. For this recipe just fill up your measuring cup with milk till it’s almost full, add vinegar to fill it all the way and let it sit for 5 minutes before using it.
  • Warm the Nutella in a microwave before adding it on the batter, this will make it easy to swirl around in the batter.
  • Chop the hazelnuts very finely, you could use a food processor or blender, this ensures that they don;t sink to the bottom of the cake while baking.
  • If the cooking time is over and your cake still isn’t baked through, cover it with tin foil and bake for another 5 minutes or as needed. This will prevent the top of the cake from burning.
