I made this banana bread recipe, using whole wheat flower, instead of using Reg refined flower (2 cups); And, because the bananas already has natural sugar, I substituted the brown sugar with 4 Reg. envelops of Splenda to the butter. It worked! No other substitutes! Came out so delicious! I try to use whole wheat flower and Splenda, as much as I can. So far all substitutes of recipes have worked. Thank you @adsactly for this awesome recipe. Sadly, I can't eat white flower nor a lot of sugar. Again, thank you!!!👏🏼👏🏼👏🏼👏🏼👏🏼👌🏼👌🏼👌🏼👌🏼💞💞💞💞
