I made some fancy banana bread today. It's vegan, gluten free, oil free, and most importantly contains chocolate chips, which are the only source of added sugar. I didn't really measure anything, and I haven't actually tasted it yet but the batter was delicious. I loosely based it on this recipe and this one.
I used 3 bananas,
~1/3c almond milk,
1T nut butter,
1 1/2 - 2c oats (1c I ground to oat flour)
~3/4c hazelnut/almond meal I made once from the leftovers when I made nut milk,
1T baking powder,
Cinnamon and baking spice,
A pinch of salt
A small handful chocolate chips
I also made a glaze out of banana and peanut butter.
