Yes, well, sort of! I haven't had a lot of success using 300 grams of applesauce in place of bananas entirely. The muffins are kind of heavy. But half mashed bananas and half applesauce works. I plan to try using 250 grams of applesauce in place of 300 grams of mashed bananas, and I think that might work. Pumpkin puree might work too!
