Ingredients
Method
- Preheat the oven to 350°F and line two baking sheets with parchment.
- Cream the butter and sugar, then beat in the egg yolks and vanilla.
- Mix in the flour and salt until a soft dough forms, then roll into 1-inch balls and roll them in the chopped hazelnuts.
- Place on the sheets and press a deep well into the center of each with your thumb.
- Bake for 10 to 12 minutes, until the edges are just golden, then press the wells down again if they puffed.
- Once cooled, spoon Nutella into each well.
Notes
Fill the cookies after baking so the Nutella stays glossy.
