- brown sugar
- melted butter
The streusel topping is mixed together. I used a small metal bowl to mix the ingredients together. I didn't really measure, but there was an equal amount of sugar and flour and I liberally sprinkled cinnamon, nutmeg and ginger across the mix before I added half a stick of melted butter.
The combination is mixed with a fork, and mine was crumbly. My banana bread was freshly poured into a bread pan and I dumped the streusel mixture over the raw bread and spread it to the edges of the pan.
The butter will melt into the bread, and the remaining flour, sugar and seasonings will fry together, resulting in a crispy, spicy coating.
The bread was baked a good hour, maybe an hour and 15 minutes.
The topping rides up with the bread baking. The bread that I created was banana bread with rhubarb. It's a wet bread, almost like a bread pudding by the time it is done baking.
Generally, banana bread is stiff enough to pick up with your fingers, but with the addition of a bunch of rhubarb, it is too sloppy to do anything but eat with a fork.
