Instructions
Preheat oven to 350 degrees F. Line two cookie sheets with parchment paper.
In bowl of food processor, process oats until fine. Add cereal and walnuts to processor with ground oatmeal and pulse until cereal is finely crushed and nuts are fairly well chopped.
Cream butter and both sugars in a mixing bowl using high speed of an electric mixer; add egg and vanilla and beat just until egg is mixed in. Add the baking powder, baking soda and salt; stir well to mix. Scrape sides of bowl and stir in flour mixture and cereal mixture.
Shape into 1 ½ inch balls, then press the balls lightly so they have slightly flat tops. That is, unless you want rounded tops. Place on cookie sheets, spacing 2 ½ inches apart and bake for 15 minutes or until edges start to brown. Cool on cookie sheet for 5 minutes, then transfer to a rack to finish cooling.
