Pre heat the oven at 225 C.
Start with making oats flour - add rolled oats in a food processor , blend it for 2-3 minutes until it becomes into powder form, no grains.
Add all purpose flour , blitz again for few seconds and now add avocado + pieces of bananas + sugar + eggs + salt + baking soda. Blitz it for 1 minute until all the ingredients are mixed together.
Take the baking sheet and line it on a baking tray, I take little amount of the batter that I am baking and put it under the baking sheet to stick the baking sheet on the baking tray. (for example 4 sides of the baking tray)
Pour the batter on the lined baking sheet in a baking tray. Spread the batter evenly.
Add white chocolate + raisins + walnuts ( no need to chop ).
Bake it for 30 - 35 minutes. Check after 30 minutes (insert a fork and see, if the batter sticks to the fork so it is not baked, if the fork comes out dry or little moist then take it out, it will look light green in colour when the batter is rising up and will change the colour to brown when it starts baking at the top.
Take it out from the baking tray and let it cool down.
