Raspberry Crumble Bars Recipe

Preheat the oven to 350 degrees F (175 degrees C). Grease an 8-inch square cake pan with cooking spray.

Combine flour sugar butter and egg in a large bowl; beat with an electric mixer until mixture resembles coarse crumbs. Measure 2 cups crumb mixture and set aside. Press remaining crumb mixture firmly into the bottom of the prepared pan.

Spread jam over the crumb mixture to within 1/2 inch from the edges. Sprinkle reserved crumb mixture over top.

Bake in the preheated oven until light golden brown 40 to 50 minutes. Remove from the oven and cool completely before cutting into 25 squares.
