I pinned this recipe a while ago. It's not hard to see the appeal of Nutella cookies. The pin I pinned actually didn't link to the right recipe, so I searched online. Basically the same recipe popped up all over the internet, but I used the one from Kirbie's cravings. I added some chopped hazelnuts to about half the batter, and both Jon and I thought they improved the cookies. So in the future, we'll be including them. The Nutella flavor is subtle but definitely present. I think Frangelico would be a good addition to pump up the hazelnut flavor even more.
1/2 cup unsalted butter, room temperature
1/3 cup brown sugar
1/3 cup white sugar
1/2 cup Nutella
1 tsp vanilla extract
1 1/2 cups all-purpose flour
1 tsp baking soda
1/4 tsp salt
1/3 cup chopped hazelnuts
Preheat oven to 350 F. Cream butter and sugars until light and fluffy. Mix in Nutella, egg, and vanilla. Combine the flour, baking soda, and salt in a separate bowl and slowly add to the wet ingredients. Mix until just combined. Stir in hazelnuts.
Drop by heaping spoonfuls onto a cookie sheet or pizza stone. Cook for 10-15 minutes, or until the tops of the cookies are starting to crackle a little.
