1 cup walnuts (6 oz.)
2 cups old-fashioned rolled oats
1/2 cup rice flour
1/4 teaspoon salt
1/2 teaspoon ground cinnamon
1/4 teaspoon allspice
1/4 teaspoon grated nutmeg
1/4 cup vegetable oil
1/3 cup brown rice syrup
1/3 cup pure maple syrup
1 tablespoon vanilla extract
3 tablespoons all-fruit preserves
1. Preheat oven to 350? F. Place walnuts on baking sheet and bake until lightly toasted, 8 to 10 minutes. Lightly brush three baking sheets with oil or line with parchment paper; set aside.
2. Meanwhile, put oats into food processor and pulse on/off six times. Add rice flour, salt, cinnamon, allspice and nutmeg and process to blend. Scrape down sides of bowl with rubber spatula, pulse two more times to thoroughly combine. Transfer mixture to large bowl.
3 While walnuts are still warm, grind them to a paste in food processor. Add oil, rice syrup, maple syrup and vanilla and process until blended and smooth. Add mixture to dry ingredients and mix until just blended (Dough will be sticky.)
4 Scoop out heaping teaspoonfuls of dough. Roll into balls and flatten to form cookies about 1 3/4 inches in diameter. (It's helpful to dip hands and utensils and water with working with this sticky dough.) With your thumb, make a deep indentation in center of each cookie. Fill each indentation with about 1/4 teaspoon fruit preserves. Place cookies on prepared baking sheets, spacing about 2 inches apart. Bake until bottoms are lightly browned, about 10 minutes. Transfer cookies to wire rack to cool.
