makes about 3 dozen
For the cookies:
2 cups all-purpose flour
1/2 teaspoon baking powder
1/4 teaspoon salt
2 sticks (1 cup) unsalted butter (1 stick melted, 1 stick softened)
3/4 cup packed light brown sugar
1 teaspoon vanilla extract
1 cup finely chopped walnuts
For the decoration:
8 oz semisweet chocolate, melted
1/2 cup finely chopped walnuts
1. Preheat the oven to 375 degrees. Line a baking sheet with parchment paper or a silpat and set aside.
2. Whisk together the flour, baking powder, and salt. Using an electric mixer, beat together the butter, brown sugar, and vanilla until light and fluffy. Mix in the flour mixture at low speed, then stir in walnuts.
3. Form 2 teaspoons of dough into an egglike shape, forming a ridge down the middle with your thumbs. Arrange the dough1 inch apart on the prepared baking sheet. Bake in batches in the middle of the oven until undersides are light brown, about 10-12 minutes. Transfer to wire racks to cool.
