Either use a hand mixer or stand mixer - mix butter and sugar together ( until fluffy) slowly add in flour and vanilla - mix - It will be a drier mixture
Melt chocolate and butter together ( I used the microwave) - just remember not to burn the chocolate --- you can set it aside till the cookies are done --- the chocolate will stay somewhat melted
Arrange the cookie dough on the sheet into the Milano cookie shape - they will not rise ( they simply bake in the same shape)
It should make about 10 cookies
Bake for 20 minutes
Let cookies cool - once cool place chocolate on one side of each cookie
Sandwich the cookies together
Enjoy!
