Preheat oven to 350 F.
Spray a loaf pan with non stick spray.
First, let’s make the lavender brown butter.
In a dry skillet, toast the lavender until it becomes fragrant.
Add the butter. Cook gently on medium heat until it gets all foamy. With a spoon, pull aside the foam. Once the butter has turned a golden light caramel color, remove from heat. Leave to cool for a few minutes.
Meanwhile, in a bowl, combine whole wheat flour, all purpose flour, baking soda, salt, clove and turmeric.
In a large bowl, combine banana, honey and eggs. Whisk until thoroughly combined.
Add brown butter and whisk to combine.
Add half the flour and mix until well incorporated.
Add remaining flour and mix until just combined.
Transfer to prepared loaf pan.
Transfer to oven and bake for 60-70 minutes, until a tester comes out clean.
Remove from oven and leave to cool for 10 minutes.
Remove from pan and leave to cool completely before slicing.
