  4. Put all the dry ingredients in a large bowl and whisk to combine.  
  5. Add the dry ingredients to the wet and stir until just combined, being careful not to overmix it. 
  6. At this point stir in the nuts.
  7. Add the batter to the prepared bread pan.
  8. Peel and cut the garnish banana in half or slice it into rounds and lay it on top of the batter. 
  9. Bake the banana bread for 50-60 minutes until a cake tester comes clean after being inserted into the middle of the bread.  
  10. Allow the bread to cool for 2-3 minutes before removing it carefully from a pan and placing it onto a cooling rack. 


FOR MUFFINS: Scoop batter into muffin tins until each muffin is 3/4 full. Bake at 178°C/350°F for 15-20 mins, or until golden brown, and set in the center (poke a toothpick in and see if it comes out clean).
