You can use oligosaccharide instead of allulose (units are ml -> g)
Combine oatmeal, almonds, sunflower seeds, etc. in a bowl.
Add eggs, bananas, and oligosaccharide, then mix into a dough.
Shape some of the dough into small, flat chip shapes.
Form the remaining dough into round cookie shapes.
Line a baking sheet with parchment paper and place the dough on top.
Bake in a preheated oven at 180°C for 15 minutes.
Transfer to a cooling rack and let cool.
