Beat the first five ingredients with an electric mixer until well combined. Mix in the pecans. Divide the dough into thirds. Form each into a smooth 1-1/2" diameter log on a sheet of waxed paper. Wrap tightly. Refrigerate at least one hour to firm. (Can be prepared ahead and refrigerated up to three days, or frozen several months. Thaw in the refrigerator before continuing.) Preheat the oven to 325
F. Remove the paper from the dough. Cut the dough into 1/4" thick slices. Arrange 1-1/2" apart on baking sheets. Bake until golden brown, 15 to 18 minutes. Transfer to paper towels and cool
completely. Store in an airtight container.
