1
Cream the butter and cheese together for about a minute until smooth.
2
Set the mixer on low, then add the flour, salt, and pepper. Combine until large crumbles form, then mix in 1 tablespoon of water.
3
Sprinkle flour onto a clean work surface then transfer the dough to it. Form the dough into a ball, then into a 12-inch log. Brush the egg wash onto the log.
4
Distribute the chopped walnuts evenly on a small baking sheet. Gently roll the log of dough in the walnuts until the log is completely coated. The walnuts shouldn't pierce the dough, but should just adhere to its surface. Wrap the log in parchment paper or plastic wrap and refrigerate for at least 30 minutes or up to 4 days.
5
Preheat the oven to 350°F. Line the baking sheet with parchment paper.
6
Using a sawing motion, cut the log into 3/8-inch pieces with a paring knife. Bake for a total of 22 minutes or until they are lightly browned. Rotate the baking sheet mid-way.
7
Cool to room temp prior to serving.
