Shortbread cookies are my very favorite, but I’m not quite sure if that is because of how amazing they taste, or because of how easy they are to make. What could be simpler than mixing together butter, sugar, and flour?
In a large bowl, cream butter and sugar until light and fluffy. Gradually stir in flour and mix well. Turn onto a lightly floured surface and knead until smooth, about 3 minutes.
Spread chopped walnuts in a rimmed cookie sheet. Press logs into walnuts, rolling to cover each side.
Wrap logs in wax paper or plastic wrap, twisting the ends tightly, and refrigerate for at least 1 hour or overnight.
Once ready to bake, preheat oven to 350 degrees. Line 2 baking sheets with parchment paper.
