Nutrition on the road - What, How and Why?

So I was experimenting a bit with foods for 4+h training rides as imo bars are way too fucking expensive. Then theres a lot of recipies around for flap-jacks or malt loaf but most of them are with much fat and/or processed sugar, which I don't like.

Some important characteristics I wanted for the food were:

• Healthy
  
• Fast & slow carbs
  
• Low fat
  
• Easy to bring in jersey pocket
  
• Easy digestible
  
• Not crumbly nor sticky, too dry or too soggy
  
• Taste good
  
  

Finally I did this recipe:

Ingredients
2 bananas (Preferably very ripe ones)
2 tbsp honey
2 handful studentenhaver which is the Dutch name for a blend of raisins and dried nuts
70g rolled oats
50g flour

Pre heat oven 170 degrees
Mash the bananas
Add the other ingredients and mix together
Make 10 portions
Bake for 20 minutes

This pic is of the first batch. The recipe has been changed a bit since but the result looks quite the same.
