preheat the oven to 350˚

to make streusel mix the dry ingredients in the streusel recipe together, then cut in the cold butter with two butter knives or a pastry blender-you can also use a food processor if you like

when mixture looks like crumbs set aside until batter is finished

lightly grease two 8x4 loaf pans OR five small aluminum foil loaf pans

melt the butter, let it cool but not solidify, then stir in the sugar

beat in the eggs, vanilla and cinnamon

next cut the tip off each thawed banana and squeeze into the bowl

stir to combine

mix the flour, salt and soda together in a separate bowl

then add the buttermilk alternately with the flour mixture to the batter, stirring to combine, it will be lumpy and unpretty, if there are still floury spots stir a little longer

stir in the chocolate chips

divide between the loaf pans and sprinkle streusel on the top of each pan, press it in lightly

bake for 45-55 minutes for big loaves or 35-40 minutes for small loaf or until a toothpick comes out moist but without crumbs

cool completely and then store wrapped in the pan unless you want to take the chance of all your streusel coming off
