Engineered Cooking

1. Preheat the oven to 375 °F.

2. In a medium mixing bowl, whisk together the flour, baking powder, and salt.

3. In a large mixing bowl, beat the butter and both sugars with an electric mixer until light and fluffy. Beat in the eggs and vanilla. On low speed, gradually add the flour mixture.

4. Place the finely chopped walnuts into a shallow bowl. Shape heaping teaspoonfuls of the dough into 1-inch balls and roll into the walnuts, pressing to coat. Place about 2 inches apart onto an ungreased baking sheet. With your thumb make a deep depression in the center of each cookie, spoon approximately ½ teaspoon into each depression.

5. Bake for 10 minutes, or until golden brown around the edges. Cool the cookies for 3 minutes on the banking sheet, then transfer to a wire cooling rack to cool completely.
