As an even healthier variant of chocolate cereal to keep fat intake down:
Every commercial chocolate cereal I have seen is way too high in sugar. Keep breakfast as bitter as you can enjoy, to keep your start of the day healthy.
Sprinkle cocoa powder onto the dry cereal. I use several dessert spoons full.
Mix the dry ingredients. The cocoa powder sticks well to most dry materials.
Add a handful of frozen blueberries, a spoon or two of low fat yoghurt, and milk.
Stir and enjoy.
