Butterscotch Wafers

In a large mixing bowl, cream together the butter and brown sugar until fluffy, about 3 minutes.

Add the eggs, one at a time, beating well after each addition. Add the salt, baking powder and flour. Mix until a very soft dough comes together. Add the nuts and mix again.

Refrigerate the dough until firm, at least an hour or more.

Preheat the oven to 375 degrees F. Line 2 baking sheets with parchment paper.

Scoop the dough by the teaspoonful onto the prepared baking sheets, leaving about 2 inches between cookies. Using a moistened hand or the bottom of a glass, flatten the balls of dough slightly.

Bake for 10 to 12 minutes, or until golden brown at the edges. Remove from the oven, cool for 1 minute on baking sheet, then transfer to a wire rack and cool completely. Store in an airtight container at room temperature.
