Can I give 99% dark chocolate to my 3 yr old child?

I don't eat traditional chocolate as its loaded with sugar, saturated fat and additives but I do occasionally eat dark chocolate. My daughter wanted to try some so I gave her a few squares and she liked it very much but is this safe for her to eat? Its very bitter tasting and almost black in color. Ingredients: Cocoa (99% min, cocoa m, cocoa powder, cocoa er), sugar, natural vanilla extract flavor.
