In a large bowl, combine the granola, flour, brown sugar and cinnamon; cut in butter until crumbly. Set aside a third of the mixture for topping. Press remaining mixture into a well-greased 9-in. square baking pan. Bake at 375° for 10 minutes.
Spread preserves over crust; sprinkle with reserved granola mixture. Bake until filling is bubbly around the edges, about 15 minutes longer. Cool on a wire rack. Cut into squares. Store in the refrigerator.
