Here's another wonderful Nutella idea as found at PinkofPerfection.com :
Nutella Chocolate Chip Cookies
2-1/4 cups all-purpose flour
1 teaspoon baking soda
1 teaspoon salt
1 cup (2 sticks) butter, softened
1/2 cup granulated sugar
1/3 cup Nutella
2 eggs
1 12-ounce package dark chocolate chips
Heat oven to 350°F. Stir together flour, baking soda and salt. Beat
butter, sugar, and Nutella in a large bowl with mixer until creamy. Add
eggs; beat well. Gradually add flour mixture, beating well. Stir in
chocolate chips. Drop by rounded teaspoons onto an ungreased cookie
sheet. Bake 10 minutes. Cookies should be crisp on underside edges and
just ever so slightly undercooked in the center. Cool on cookie sheet,
then transfer to a plate.
