I haven't had Nutella since I was a kid, and had almost forgotten how good it is.
Delicious. Go and make these. Right now.

Ingredients
- 4.5 ounces all-purpose flour (about 1 cup)
 - 1 cup powdered sugar
 - 1/3 cup unsweetened cocoa
 - 1/4 teaspoon salt
 - 1/2 cup butter, softened
 - 2 large egg yolks
 - 1 teaspoon instant espresso (optional) [I used coffee liqueur instead]
 - 1/2 teaspoon vanilla extract
 - 2/3 cup finely chopped hazelnuts, toasted [I skipped these]
 - 1/3 cup hazelnut-chocolate spread (such as Nutella)
 
Preparation
1. Preheat oven to 350°.
2. Weigh or lightly spoon  flour into a dry measuring cup; level with a knife. Combine flour,  sugar, cocoa, and salt; stir with a whisk. Place butter in a large bowl,  and beat with a mixer at medium speed until light and fluffy (about 2  minutes). Stir egg yolks with a whisk, adding espresso, if desired. Add  the yolk mixture and vanilla to butter; beat well. Add flour mixture to  butter mixture; beat at low speed just until combined. [I mixed it in with a fork; if you beat it, the dry ingredients will go flying.]
3. Turn  dough out onto a sheet of wax paper; knead 6 times or until smooth and  shiny. Shape dough into 28 (1-inch) balls. Roll sides of balls in nuts,  pressing gently. Arrange balls 1 inch apart on baking sheets lined with  parchment paper. Press thumb into center of each cookie, leaving an  indentation. Bake, 1 batch at a time, at 350° for 10 minutes. Remove  cookies from pans; cool completely on wire racks. Spoon a scant 1/2  teaspoon hazelnut-chocolate spread into center of each cookie.
