Chocolate Hazelnut Cookies

I think Santa would like these...

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)
• 1/2 teaspoon vanilla extract
• 2/3 cup finely chopped hazelnuts, toasted (I skipped those)
• 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.

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 hazelnut-chocolate spread into center of each cookie.

4. Enjoy with a glass of milk!
