Walnut Cookies

These piped walnut cookies are closer to a European tea biscuit than an American drop cookie. Toasted walnuts get ground fine in a food processor, then folded into a simple butter-sugar-flour dough that bakes low and slow until barely golden.

Toasting the walnuts first is a must. Raw walnuts taste flat and slightly bitter. A few minutes in a low oven brings out their natural oils and deepens the flavor from mild to rich and almost caramel-like. Let them cool completely before grinding or the heat will turn them into nut butter.

The dough pipes beautifully through a plain tip because of the high butter-to-flour ratio. No eggs in this recipe, which is what gives the finished cookies their signature sandy, melt-in-your-mouth crumble. The powdered sugar dusted on top after cooling adds sweetness without changing that delicate texture.

Kitchen Tips

• Grind the walnuts in short pulses. You want a fine, sandy texture. One pulse too many and you’ll have walnut paste that makes the dough greasy.
• If you don’t have a piping bag, roll the dough into small balls by hand. They’ll be a bit rounder but taste identical.
• Bake until just pale brown, not golden. These cookies firm up significantly as they cool, so pulling them early prevents them from turning hard.

Variations

• Use almonds or pecans in place of walnuts for a different nut flavor. Toasting still applies.
• Add ½ teaspoon of almond extract alongside the vanilla for a more complex, almost marzipan-like note.
• Dip the cooled cookies halfway into melted dark chocolate for a more formal presentation.
