Coffee Walnut Cookies

👨‍🍳 Method

To assemble

1. 1
   Preheat the oven to 170°C (340°F) and line a baking sheet with parchment paper.

   ⚙ Preheating the OvenOven

   💡Put things in the oven only once it's reached temperature, after the heating light has gone off: an oven that hasn't reached temperature changes baking times, and the bake burns outside or stays underbaked.
2. 2
   Sift the flour and baking powder into a bowl.

3. 3
   Whip the soft butter with the brown sugar, to a smooth, pale mixture.

   💡Cream the butter soft, at room temperature: cold butter doesn't take in air, and melted butter doesn't hold it.
4. 4
   Add the egg, instant coffee and vanilla and mix well.
5. 5
   Add the flour, baking powder and salt and mix just until a dough forms.

   💡Mix in the flour only until a dough forms: long kneading develops gluten, and the cookies come out hard instead of crumbly.
6. 6
   Fold the nuts into the dough gently.

   💡Take the cookies out while they still look soft: they firm up as they cool, and long baking dries them out.

   💡Check by the cue (until…), not just the clock: every oven bakes a little differently.
