Just like the name implied, I modified my original banana recipe to make it 100% whole wheat with chia seeds. Next time I would add additional 1 Tbsp. of ground flaxseeds into the mixture instead of using it as topping. By adding the whole wheat and flaxseed cereal, it would be crispy when it was warm out of the oven but it would turn soft later. So, if you would like to eat it right away or on the day it was baked, then it would be a good idea, if not, just omit it and add the ground flaxseeds into the mixture before baking (I added it in the recipe for your convenient).
This muffin is soft and not very sweet (just nice for Asian taste bud). I purposely cutting down on the sugar to make it healthier. I hope you like it!
