sourdough vegan cupcakes

my sourdough version:
1/3 c sourdough starter
1/3 c mylk
1 c flour (1/2 sorghum, 1/4 teff, 1/4 arrowroot)
sour overnight

next morning, mix 1 cup cooked sweet potato
1 ripe banana
1/4 c olive oil
1/4 c honey
1 tsp cinnamon
1/2 tsp each cardamom & cloves
1/2 tsp baking powder
1/2 tsp baking soda

combine with soured ingredients
bake @ 350F until done (20 min or more)

result: pretty tasty, quite moist, nice little cupcake
