I lied. These cookies actually have a little more than just Nutella. I also added some Toffifay candies (as seen above.) I figured they went with the chocolate-hazelnut theme, and would add a nice extra crunch. I think I was right!
To make these cookies you can use this same shortbread recipe, just don't add any baker's cocoa or coffee! After the dough is chilled, to stuff the cookies take about 2 tbs of dough and flatten it. Top with about a tablespoon of Nutella (2 tbs if you think you have enough dough to cover it) and a Toffifay candy. Then wrap the cookie up, closing the edges at the top until it looks like a Hershey's Kiss or a cute little dumpling :) Make sure there is no Nutella seeping out and that it is closed up tight.
Pop them in the oven for about 14 minutes and you are all done!
