If you are a fan of Nutella or chocolate, those rich, crispy, chocolatey and nutty cookies are sure a real treat. If you can't find spelt, just use plain wheat flour instead.
- Whisk together the spelt flour, baking soda and salt in a mixing bowl.
- Cream the softened butter and sugar on medium speed until light and fluffy. Add eggs, one at a time, until completely incorporated. Add in nutella and coffee liquor.
- Sift the flour mixture into the nutella mixture. Mix until just incorporated. Cover with a plastic wrap and chill at least 4 hours or overnight.
- Line two baking sheets with parchment paper. Preheat the oven to 175C/350F. Shape the cookie dough into balls and roll in the chopped pistachios. Place them on the prepared baking sheets, leaving about 1-inch between cookies. Bake for 15 minutes. Let the cookies cool on the baking sheet for 5 minutes, then transfer to wire racks to cool completely.
