Even my very picky, sugar loving teen likes these.
Only sweeteners are bananas and some honey/maple syrup.
Here's the list of ingredients for your perusal, before you go to the link:
Ripe bananas
Honey/maple syrup
Eggs (I think an egg sub would be fine)
Baking soda
Peanut butter (or any nut/seed butter)
Oat flour (don't see why any GF flour wouldn't work)
Chia seeds (very important for thickening the batter)
Craisins, raisins, and pepitas. (Could sub whatever you like)
Cinnamon
Vanilla
The batter has to chill at least 4 hours. The recipe said to use a 1/4 cup scoop for each cookie but I used a regular cookie scoop and got 24 cookies instead of 12.
Normally, sweets make me feel kinda icky but these don't.
