Preheat oven to 325. Grease some 8 oz mason jars.
Cream together the browned butter and sugar. Add the eggs and mashed bananas.
In a separate bowl, sift the bread flour, baking powder, baking soda, salt, cinnamon and cloves. Add this to the banana mixture.
For the crumble, simply mix the crumble ingredients together.
Fill the jars. The most effective way to do this is to fill a piping bag with the dough. Pipe this into the mason jars, filling about three quarters of the way. Then put some crumble on top.
Put crumble on top, bake for 35 minutes.
This can also be made into muffins, just fill the muffin pans about three quarters as well. Bake for 20 mins.
