Pecan Oat Sandies

These shortbread cookies are sometimes called Mexican wedding cookies or Russian tea cakes, but the oat-and-pecan version is the Southern grandmother’s twist. Rolled oats add a chewy texture against the buttery crumble, while pecans bring nutty depth.

Using powdered sugar instead of granulated is the key technique. The fine sugar dissolves smoothly into the butter and gives the cookies their signature melt-in-your-mouth tenderness. Granulated sugar leaves grainy spots that ruin the texture.

No eggs, no leavening. These cookies rely entirely on butter and the small bit of moisture in the powdered sugar to hold their shape. That’s why slow baking at 325°F (165°C) matters so much. Higher heat melts the butter faster than the dough can set, leaving you with greasy puddles instead of cookies.

Shape them however you like: balls, crescents, or logs. The half-hour bake time gives all three shapes time to set without overbrowning. The cookies should look pale beige when done, not golden brown. They firm up as they cool.

Dust generously with powdered sugar while still warm so the sugar adheres to the surface.

Pro Tips

• Toast the pecans for 5 minutes in a dry pan before chopping. Untoasted pecans taste flat in the buttery crumb.
• Use real butter, not margarine, for the most tender result. Butter’s milk fats give shortbread its character.
• Let cool 5 minutes before sifting on sugar so the cookies hold their shape and the sugar coats evenly.
• For an extra-snowy look, dust again with powdered sugar after the cookies have cooled completely.

Variations

• Stir in a quarter teaspoon of cinnamon or cardamom to the dough for warm spice notes.
• Swap pecans for chopped walnuts, hazelnuts, or almonds for different nutty character.
• Add a half teaspoon of orange zest to the dough for a citrus twist.
