Not always at home to eat chocolate and if they cover a lot of cookies, then leave a few tiles, and it's not cheap! This recipe gave me the pastry, glaze the result is a true professional and also delicious and very shiny, which is also very important, good freezes. Looking at the website, not found, but if you do... please do not be offended!
Melt the butter, preferably it is oil with high fat content, because it freezes better.
Add cocoa powder, stir, then add condensed milk, stir all together and all the icing ready!
If you add more cocoa glaze turns darker, shokoladna!
Here I am in the glaze, "atoned for" cookies :)))
