Preheat oven to 350°(F). Line an 8-inch square baking pan with parchment paper, extending paper over edges. Lightly grease parchment; set aside.
Combine all crumb mixture ingredients in bowl (the first 6 ingredients). Beat at low speed, scraping down the sides of the bowl often, until mixture resembles coarse crumbs. Reserve 2 cups crumb mixture; set aside.
Press remaining crumb mixture on bottom of prepared baking pan. Spread preserves to within 1/2 inch of edge. Crumble reserved crumb mixture over preserves.
Bake 40-50 minutes or until lightly browned. Cool completely; cut into bars.
Notes
