I always knock the nuts in the pack into small pieces, as well as the cornflakes. It`s best to mix everything in a large bowl so that the cocoa and cinnamon are nicely distributed.
Then fill into a large container, then you can simply take out your portion every morning. I like to roast the sunflower seeds, they give them a nice roasted aroma.
A simple, conscious mixture that knows what`s inside, for little money and little work.
You can of course use any combination of grains or spices, depending on your taste.
