Once you've baked the cookie/biscuits allow to cool and then add frosting/icing and decorate anyway you like. Now, I like the dark chocolate (90%) swirls on number two
... but which cookie/biscuit would you choose?
Studies show that dark chocolate (not the sugary type) can improve health and lower the risk of heart disease.
Dark Chocolate is Very Nutritious:
If you buy quality dark chocolate with a high cocoa content, then it is actually quite nutritious.
It contains a decent amount of soluble fibre and is loaded with minerals.
A 100 gram bar of dark chocolate with 70-85% cocoa contains:
11 grams of fibre.
67% of the RDA for Iron.
58% of the RDA for Magnesium.
89% of the RDA for Copper.
98% of the RDA for Manganese.
It also has plenty of potassium, phosphorus, zinc and selenium."
