1 (18.25 ounce) box yellow cake mix
1 1/2 cups quick cooking oats
3/4 cup melted butter
1 (12 ounce) jar raspberry jam
1 tablespoon water

Preheat oven to 375 degrees F.

Combine cake mix and oats. Stir in melted butter until mixture is crumbly. Put about 3 cups of mixture into a 9 x 13-inch pan and press firmly.

Combine jam and water. Spoon over crumb mixture, spreading evenly.

Cover with remaining crumb mixture. Pat firmly to even out the top. Bake for 20-25 minutes.

Cool before cutting into bars.

Serves 10 to 12.
